It was a fairly active night in weather across northwest Oregon and southwest Washington. We had a few strong to severe thunderstorms from the Cascades to the Oregon / Washington Coast. As I write this discussion around 3:00 A.M., most of the storms are pushing offshore over the Pacific Ocean. It’s still possible that a shower or storm could pop up before sunrise, but we should see mainly dry weather today. The marine layer will gradually burn off to sunshine later this afternoon with highs near 80 degrees in the metro area. Our weather pattern turns much more quiet between Thursday and Sunday. We’ll find ourselves back in the “goldilocks zone”, with cooler low pressure to our northwest, and a hot high pressure system to our southeast. Expect seasonable temperatures, with highs in the low to mid 80s, and overnight lows in the 50s and low 60s.High pressure will begin to expand out of the Southwest starting early next week. This will mark the start of another heat wave, with afternoon temperatures rebounding into the 90s. It could get even hotter between mid to late week, so stay tuned for updates. Have a great Wednesday!
We have seen some light showers around the metro area today, but no measurable rainfall yet at PDX. Through the night, we will see clouds moving in and this evening a shower or thunderstorm is possible.
We managed to stay below 90 degrees on Monday due to mid-level clouds streaming in from the south. Those clouds are linked to monsoonal moisture getting pulled in by a system southwest of Oregon (over the Pacific Ocean). That low pressure system will continue to drift northward along our coastline over the next couple of days. Isolated showers and even a few thunderstorms will be possible, but the best chance for that activity will be along and east of the Cascades. The National Weather Service has issued a red flag warning due to the lightning threat and elevated fire danger. Besides the isolated showers and storms, we’ll see a mix of clouds and sunshine today. Highs across the metro area will reach the mid to upper 80s. Wednesday should be quite a bit cooler with highs struggling to reach 80 degrees. The remainder of the week looks pretty uneventful weather-wise. A patchy marine layer will be possible each morning through Saturday, followed by abundant afternoon sunshine. Highs will reach the mid 80s Thursday through Saturday. High pressure will begin to nudge its way out of the Southwest between Sunday & Monday, bringing lots of sunshine & warming temps. Highs will top out in the upper 80s and low 90s (and could be warmer beyond Monday).Have a great Tuesday!
We will see some clouds through the night and overnight there is a chance that we could see a few isolated showers. Expect morning clouds tomorrow, clearing to a sunnier afternoon. By evening we will see the return of some clouds and into the night we have a chance of seeing a shower or possibly a thunderstorm.
Good Monday morning! We officially hit 100 degrees yesterday at PDX. Today we wrap up our latest heat wave with slightly cooler temperatures. Under mostly sunny skies we will warm to 93 degrees. We change things up at bit tomorrow and Wednesday with some clouds passing through, bringing a chance of a scattered shower and possible thunderstorm and highs going to 86 tomorrow and 80 on Wednesday. Perfect summer weather for Thursday through Sunday with mostly sunny skies and highs in the mid-80s.
Hello and happy Friday!It's been a beautiful day out there! Plenty of sunshine for everybody and high temperatures right around average, we anticipate we'll top out in the mid 80s this evening in Portland. We're watching for potential thunderstorm activity in far southeast Oregon, but besides that it'll be a calm and mostly clear night for our region.Things will start to get toasty Saturday afternoon. High temperatures in the low to mid 90s will kick off our 3-day heat wave. Sunday still looks to be the hottest day-- good chance we will see metro area temperatures in the upper 90s or low 100s.
Some would consider today to be a “perfect” summer day in Portland. Partly cloudy skies turning mainly sunny in the afternoon. Temperatures are peaking out in the mid-upper 70s. Skies continue clearing tonight and we’ll see the coolest night in at least two weeks! All of us drop into the 50s and some of the coolest outlying areas drop into the 40s. Skies turn sunny through Monday as temperatures warm.
A thick marine layer is surging inland early on this Thursday, and will bring chances of drizzle and gray skies through about midday. As we head into the afternoon, clouds will gradually start to clear out. Due to the late clearing, high temperatures will struggle to reach 80 degrees. The metro area should top out somewhere between 75-78 degrees. This cooler and cloudier weather pattern is linked to a trough of low pressure digging into the Northwest. This system won’t be around for too long, departing to the northeast by Friday & Saturday. Once that system moves out of our region, high pressure will expand out of the west. Unfortunately, we’re looking at another heat wave, albeit a much shorter one (between Saturday and Monday). The hottest day should be Sunday with high temps around 100 degrees. Prepare for warmer nights as well. Luckily, this system won’t stall like the last one, so temperatures should begin to cool down Tuesday and Wednesday. An upper level low will drift in from the southwest around midweek, bringing more clouds and chances for showers & isolated thunderstorms. Highs will dip into the low to mid 80s, and should persist through the remainder of the week. Have a great Thursday!
It’s another warm summer day, not hot, but very warm. We’re topping out in the mid-upper 80s late this afternoon under totally sunny skies. Expect a nice evening as temperatures cool, due to marine air surging inland. A weak weather system moves inland late tonight, giving us our first thick morning cloud cover that we’ve seen in about 10 days. There’s even a slight chance of a shower or sprinkle out of the gray sky. But by midday the clouds start to break up and Thursday afternoon will be mainly sunny.
It turned out to be a very warm day on Tuesday, and we’re looking at much of the same this afternoon. Low clouds are mainly confined to the coast and the lower Columbia River early on this Wednesday. We could see a few patchy clouds just after sunrise, but today should turn out to be a sunny day across our western valleys. By lunchtime, temperatures should at least be around the mid 70s, and by the end of the afternoon, highs will reach the mid to upper 80s. Our coolest day will likely be Thursday as marine air surges inland. This will be linked to a trough of low pressure digging into the Northwest. Cloudy skies & areas of drizzle can be expected along the Coast, the Coast Range and the Cascade Foothills. A few spots of drizzle might even occur in parts of the metro area. Expect a gradual clearing of our skies Thursday afternoon with highs in the mid to upper 70s.High pressure will expand over the Pacific Northwest starting Friday and lasting through at least Monday. Temperatures will rebound into the mid 80s Friday afternoon, and the low to mid 90s Saturday-Monday. Overnights shouldn’t be quite as warm as our previous heat wave. By Tuesday, an upper level low will move in from the southwest, bringing more clouds and cooling temperatures. Have a great Wednesday!
It’s a cloudy start to the day along the coast, and the marine layer is pushing inland. Portions of our western valleys will begin the day with cloud cover, but will quickly clear out to sunshine. In addition to the morning clouds, temperatures are about 5-10 degrees cooler across much of the metro area. It’s still going to be a warm afternoon, but at least a couple of degrees cooler than yesterday. Expect highs to reach the mid to upper 80s. Wednesday will basically be a repeat of today with less A.M. cloud cover. A trough of low pressure will be dipping over Washington on Thursday, bringing even more cloud cover to southwest Washington and northwest Oregon. Clouds will gradually clear out to sunshine. This cooler trough will drop high temperatures into the mid to upper 70s. The trough will depart to the northeast between Friday and Saturday, allowing for high pressure to expand back overhead. This will bring another warming trend with high temps rebounding into the 80s & 90s. All signs point to another heat wave, albeit a much shorter one than last week’s. Overnights will remain on the cooler side of things, but will trend back into the low to mid 60s Sunday and Monday. There’s no sign of any significant rain over the next 7 to 10 days. Have a great Tuesday!
It’s a bit cooler out there this morning compared to previous mornings, but still on the warm side of things across the metro area. Temperatures won’t be quite as hot this afternoon. High pressure is starting to back off a bit. We also have mid-level clouds and thin wildfire smoke that will be limiting our sunshine. It’ll still turn hot for a couple of hours late this afternoon, with high temps getting close to 90 degrees. Scattered showers and thunderstorms are expected in parts of central & eastern Oregon. Most locations west of the Cascades will stay dry, but a few sprinkles can’t be ruled out. Our cooling trend should continue through midweek. While it won’t necessarily be cool out there, temperatures will be much better than last week. Expect a few afternoons between the upper 70s & mid 80s, with cooler overnights in the 50s and low 60s. High pressure looks like it will expand out of the Four Corners and Great Basin this weekend, warming us back into the low 90s. Have a great workweek!
Alright, I think everyone is getting tired of this heat wave now, but we have another two days to go before cooler weather arrives. The National Weather Service has extended the excessive heat warning through Sunday for the Willamette Valley and interior southwest Washington. The Cascades will also be under a heat advisory through the end of the weekend. It’s not just the afternoon temperatures that are concerning. Overnight lows will struggle to fall into the 60s tonight and Saturday night, especially across the metro area. It’ll feel pretty sticky out there as more moisture creeps in from the coast. Our weather will begin to trend cooler between Sunday and Monday as a weak upper level low drifts toward the region. This system could bring a few headaches in the form of isolated thunderstorms. The most favorable locations for thunderstorms will be in the Cascades. Our heat wave has really dried out the vegetation, so lightning will be capable of sparking up a wildfire. Let’s hope that doesn’t happen. Any storms that develop over the Cascades will want to drift to the east. A shower or rogue t-storm can’t be ruled out in our western valleys, but most locations should stay dry west of the Cascades. A trough of low pressure will dip into our region around midweek, bringing more clouds and cooler temperatures. Daytime highs will range between the mid to upper 70s, with overnight lows in the 50s. Boy does that sound refreshing! Have a great weekend!
It’s another hot day inland across Oregon & southwest Washington. Similar to Wednesday, onshore flow (wind directed from the coast to areas inland) is keeping a lot of our western valley a bit cooler than previously anticipated. In past heat waves, wind directed from land to sea (offshore wind) dries out our air and warms us up tremendously. That has not been the case during this heat wave. We’ve only managed to exceed 100 degrees one time. Over the next couple of days, the heat dome will gradually move over the top of us. Temperatures will top out between the upper 90s and low 100s. Overnight lows will struggle to fall into the 60s, especially in the city of Portland. It’ll feel quite humid out there as dew points rise into the 60s.The ridge of high pressure will begin to move southeast of our region between Sunday & Monday, dropping highs back into the low 90s and 80s. Sunday should mark the final day of this extended heat wave. Next week looks much more normal for this time of year, with highs ranging between the upper 70s and low 80s. Overnight lows will also turn cooler, falling back into the low 60s and 50s.There’s no sign of significant rain, or another major heat wave in the next 10 days. Stay cool out there!
It’s turning out to be another hot day inland, and a cool day along the coast. Some of that cooler marine air seeped into our western valleys early this morning, allowing temps to fall into the 60s. Temperatures haven’t been rebounding as quickly today, partially due to the smog and thin wildfire smoke in our air. We’ll finish up the day around 97-100 degrees at PDX, coming up shy of the daily record high of 103 degrees. Temperatures will struggle to fall into the 60s, but we’ll get at least a few hours around sunrise in the mid to upper 60s.Prepare for another 3 days of extreme heat across our western valleys as this large heat dome inches across the region. Thursday through Saturday should feature highs in the 100-103 degree range from Portland to Salem. Mid to upper level winds should start to veer out of the southwest by Friday, clearing most of the thin wildfire smoke out of here. Skies will turn more blue as we wrap up the workweek. Sunday will be noticeably cooler as the ridge moves southeast and onshore flow strengthens. Temperatures will top out in the low 90s, marking the final day of this long heat wave. A trough of low pressure will start to move overhead early next week, bringing more clouds and cooling temperatures. Daytime highs may actually be several degrees below normal between Monday and Wednesday. Boy that sounds refreshing! Stay cool out there!
It’s turning out to be another scorcher across the metro area (and beyond). Temperatures are a couple of degrees warmer than Monday, so we should finish the day around 99-102 at PDX. A large ridge of high pressure is inching its way over the Pacific Northwest, and will keep afternoons very hot through Saturday. An excessive heat warning was extended for our western valleys through Saturday evening. Overnight lows will be a bit warmer the next couple of nights, struggling to fall into the 60s. Along the coast, an onshore wind (wind directed from the ocean to land) will keep highs in the 60s and 70s. It looks like we will escape this heat wave without dealing with that hot & dry offshore wind. An air quality advisory has also been issued for the Portland/Vancouver metro area. Photochemical smog (A.K.A. ozone) is becoming more of an issue. This is a pollutant that forms when sunlight interacts with the gases that come out vehicles. It’s a fairly common thing to see during summertime, especially during hot and sunny stretches with light wind. You might consider reducing your time outdoors if you have respiratory issues. Our skies are also turning hazy from wildfire smoke drifting in from California. Smoke particles may reduce a bit of the sunshine coming in, but it won’t do much to deter heating. Daytime highs should still reach 98-103 through Friday (and potentially Saturday).Toward the end of the weekend and early next week, the heat dome will start to move southeast of our region, opening the door to a cooler trough of low pressure. We don’t have any rain coming early next week, but a strengthening onshore flow should bring more clouds and cooler temps. Daytime highs will drop back into the 80s, with overnight lows in the 50s and low 60s.Stay cool out there!
It’s a hot Monday across northwest Oregon and southwest Washington, with the exception to some of our coastal communities. As of the 3:00 P.M. observation, PDX has already reach 94 degrees. We’re about 6 degrees warmer than this time yesterday, and will finish up the afternoon around 97-99 degrees. Skies are clear, and will remain that way inland through most of tomorrow. Our hottest days of the week should be Tuesday-Thursday as the heat ridge builds overhead. Temperatures will soar to around 100 degrees, with overnight lows barely dropping into the 60s. Mother Nature is throwing a bit of a curveball at us though. A large wildfire is burning near Yosemite National Park in California called the Oak Fire. Upper level winds will send some of that wildfire smoke from California across Oregon between tomorrow & Wednesday. Based off of high resolution computer models, we probably won’t see hazy skies until late Tuesday. Don’t be surprised if it arrives earlier though. This will lead to a couple of hazier days Wednesday and Thursday. Smoke will be thin and shouldn’t reduce our surface level air quality too much, but we’ll keep a close eye on it and let you know if that changes. If the smoke turns a bit thicker, highs will struggle to hit 100 degrees. I’m confident the heat wave will continue through Saturday, but a minor cooling trend will be taking place. It’s possible we’ll have one more afternoon in the low 90s on Sunday. By early next week, our temperatures will trend back into the mid 80s, which is much more normal for this time of year. There’s no sign of significant rain for the next 10 days. Stay cool out there!
Portland will be in the upper 90s tomorrow, and it's still looking likely that we'll see three days in a row of triple digit temperatures-- Tuesday through Thursday. We'll be right around 100 on Friday, too, so that could turn into a four-day streak.
Our high temperatures will be much warmer Sunday-- in the low 90s for the Portland metro. Our extended heat wave really kicks off Monday with temperatures expected in the upper 90s, then three days of likely triple digits will follow.
This morning we are starting with morning clouds again, however for most it looks like by lunchtime or so, we should see fairly clear skies. Those clouds will be heaviest in the eastern part of the metro.
What a nice summer day today…morning clouds broke out to sunshine and now all inland areas are clear. Temperatures have been very nice as well; we’ve only topped out in the upper 70s. Expect similar weather tomorrow except the low clouds will break up earlier and tend to be mainly in east metro. Temperatures rise a bit too and we should see temperatures into the lower 80s tomorrow afternoon. A pleasant Saturday is ahead!
Our western valleys experienced a cool surge of marine air overnight, leading to the formation of the marine layer. Most locations west of the Cascades are under low clouds this morning. It’s possible you’ll encounter some areas of drizzle, especially along the coast and the Cascade Foothills. Clouds will dictate how warm we get this afternoon. If the clouds start to break around lunchtime, highs should reach the upper 70s. If lots of clouds linger into 1:00-2:00 P.M., we may only reach the mid 70s. A breezy northwest wind will kick in this evening. Enjoy the cooler, refreshing weather! Clouds look like they’ll clear earlier on Saturday, and we should only have patchy morning clouds around Sunday. Temperatures will rise into the low to mid 80s Saturday afternoon, and should rebound into the low 90s on Sunday. Sunday will mark the beginning of a long stretch of hot weather. A large ridge of high pressure (or heat dome) will shift over the region between the end of the weekend and late next week. Each day through about Thursday should feature warmer temperatures. Highs will climb into the mid to upper 90s on Monday, and will be right around 100 degrees Tuesday through Thursday. During that time frame, our overnight lows will turn dangerously warm. Typically in big heat waves, we get a dry offshore wind. Unfortunately, that won’t be the case next week. In fact, a bit of an onshore flow may keep our dew points elevated, and temperatures will struggle to fall into the 60s across the metro area. Highs should dip back into the 90s by the end of next week, but 90+ degree afternoons may persist through next weekend. Hope you all have a great Friday!
Other than a few thin high clouds, we’ve seen mainly sunny skies today with temperatures running a bit cooler than yesterday. No heat today with temperatures remaining below 90 is the start of a 3 day stretch of comfortable weather.A stronger push of cool marine air tonight means widespread clouds tomorrow morning. They may be thick enough to produce a few spots of drizzle too. The result is a much cooler day tomorrow with a gray start. By afternoon sunshine returns and it should be a refreshing day as temperatures remain in the 70s. Saturday will be slightly warmer with less cloud cover and no spots of drizzle.
The last two days have featured completely clear skies inland, but that’s expected to change over the next few days. A weak upper level disturbance is pushing into the region, strengthening the onshore flow and pushing the marine layer inland. Expect to see partly cloudy skies this morning, followed by mostly sunny skies this afternoon. This upper level low is also ushering in cooler air, so temperatures will be more comfortable over the next few afternoons. We’ll still be on the warm side of things this afternoon. Highs will reach the mid 80s from the metro area to the central Willamette Valley. Clouds will be stubborn to clear out along the coast, so expect a cooler day with highs in the 60s. Tomorrow will be the coolest day over the next week. Expect a stronger push of marine air, bringing widespread low clouds to our western valleys. Clouds will gradually clear out during the afternoon, and highs will struggle to reach 80 degrees. Patchy drizzle can’t be ruled out during the A.M. hours. Onshore flow will weaken a bit on Saturday, allowing clouds to clear out earlier. Highs will return to the low to mid 80s. We’re keeping a close eye on next week. All of our computer models are showing a heat wave starting between Sunday and Monday, but they’re not in complete agreement on how hot it will get. It still looks like the hottest weather will occur around midweek with highs near 100 degrees. The heat wave could also last through the end of the workweek. Enjoy the slightly cooler conditions, and have a great Thursday!
It’s another hot afternoon in Portland; we are topping out in the lower 90s today. Today should be the last hot day until Sunday since some cooler ocean air pours inland tonight. Temperatures should be slightly cooler tonight; mainly 50s in the metro area. That cooler air should keep us in the 80s tomorrow. A much stronger push of the cool marine air drops temperatures further Friday and Saturday.
We’re kicking off our Wednesday with clear skies inland and mild temperatures. Most cities across our interior valleys have dropped into the 60s, but we’re running about 3-6 degrees warmer than yesterday morning. Due to the sunny skies and warmer start, temperatures should reach about 90-93 degrees this afternoon. Today will be the last hot day for a few days. A weak upper level trough will swing across the region between Thursday and Friday. This system will help strengthen our onshore flow and provide us with more cloud cover. Each day should bring afternoon sunshine, but Friday will probably feature the most stubborn marine layer. Highs will dip into the 80s and 70s between Thursday and Saturday. High pressure will expand out of the eastern Pacific and over the Pacific Northwest between Sunday and Monday. This will begin a long stretch of hot afternoons. Highs will top out near 90 degrees on Sunday, and should be in the upper 90s and low 100s Monday & Tuesday. We are still tweaking the forecast as more data comes in, but most signs keep highs above 90 degrees through at least July 28th (Thursday).Make sure you’re watering your gardens daily. Besides a chance of drizzle on Friday, there’s no rain in sight! Have a great Wednesday!
It’s a hot afternoon with temperatures right around 90 degrees in the Portland/Vancouver/Salem area. It should be a very nice midsummer evening with temperatures falling back into the 70s after sunset. Eventually even the warmest parts of the city get down to around 60 degrees. No need for much air-conditioning with these comfortable nights…for most of us. Tomorrow will be similar, starting in the 50s and then ending up near 90 by late afternoon.
Get ready for some hot weather inland over the next couple of days. High pressure is nudging its way in from the southwest, keeping most of our interior valleys clear of low clouds. Expect sunshine pretty much all day long with high temperatures around 90 degrees. Wednesday will basically be a repeat of today with sunshine from start to finish and highs near 90 degrees. Toward the end of the workweek, a weak upper level trough will slide over the region. This system will bring more cloud cover, especially during the A.M. hours. It will also usher in cooler air. Daytime highs will dip into the 70s and 80s, with overnight lows in the mid to upper 50s. There could be some morning drizzle along the coast between Thursday and Saturday, but conditions should stay dry inland. High pressure will expand over the Pacific Northwest next week. Most signs point to another warming trend, with afternoon highs reaching the low to mid 90s. We’re still making adjustments to this part of the forecast, so stay tuned for updates. Have a great Tuesday!
Our stable summertime weather pattern is here and likely remains in place through at least the next 10 days. This is the most reliable weather time of the entire year in NW Oregon and SW Washington. Enjoy! That means high temperatures at/above 75 degrees through the next 10 days and rain is very unlikely through the end of the month.
Good morning! Clouds are gradually building in across the interior lowlands of northwest Oregon and southwest Washington. The marine layer won’t be as extensive or stubborn to clear out today, so expect to see a mostly sunny Monday. Temperatures will rise into the low to mid 80s across the metro area, with a breezy northwest wind kicking in late in the day. Onshore flow will weaken over the next couple of days as a ridge of high pressure expands out of the Great Basin. We have a couple of hot afternoons on the way. Expect abundant sunshine Tuesday and Wednesday with highs reaching about 90 degrees. High pressure will back off by Thursday as a weak disturbance approaches from the west. This will strengthen our onshore flow, bringing morning clouds and slightly cooler afternoons. Highs will range between low to mid 80s to wrap up the week. There are some signs that hot weather could return next week, but that’s not a lock just yet. Check back in for updates. Little to no rain is anticipated for the remainder of the month. Have a great Monday!
It will be a very cool start to Monday, with overnight temperatures tonight in the low to mid 50s for the metro area. Expect partly cloudy skies to start the day, then a sunny afternoon and temperatures in the low 80s.
Expect a cloudy start with the slight possibility of some drizzle here in the Portland area. Through the afternoon clouds will gradually clear, but it will be slow and only to partly cloudy skies this evening.
