Good afternoon!

Most of the metro area is experiencing a borderline hot afternoon with temperatures in the upper 80s and low 90s. We’ll end the day around 90-91 degrees at PDX. You may have also noticed the haziness out there. Wildfire smoke is drifting out of northern California, and will continue to do so for the next 24-48 hours. Air quality shouldn’t diminish a whole lot, as smoke is mostly confined to the mid to upper levels of the atmosphere.

High pressure will remain parked to the east of us through Wednesday, keeping afternoons hot and a southerly flow in place. Hazy sunshine is anticipated Tuesday, and at least for part of Wednesday. Between Wednesday and Thursday, our upper level wind will turn more out of the southwest, pushing smoke to the northeast. This is around when conditions will start to cool down. Expect highs to trend from the 90s back to the low to mid 80s by Thursday afternoon.

Between Thursday and Friday, a cooler trough of low pressure will make its approach out of the northwest. This system will push clouds back into the picture, as well as showery conditions. The best chance for measurable rain will be across northwest Oregon and western Washington. Points to the south and east of the metro area have less of a chance at seeing a soaking rain. That same system will drop our highs into the 70s Friday-Sunday.

Stay cool out there. Changes aren’t far away!

What a warm day! Temperatures clipped the 70 degree mark in the metro area today; on November 4th. Portland was just one degree shy of the 69 degree record, and Troutdale broke it at 69 degrees. Even warmer temps to our south and east. It was the warmest day in the past three weeks in Portland

I see The Dalles, Meacham, and Yakima all broke record highs for the date. Of course it was just two days ago that Redmond broke their all-time November high temperature record of 76...reaching 80 degrees!

In fact it's a bit strange that our temperatures have gone uphill in the time of year they typically go down. Remember that 48 degree sunny day with a gusty east wind? That was the coldest so far this season

I've been negligent in posting the past week or so. Slow weather, working on new weather graphics, and election drama has distracted me. But as we move deeper into November the weather action usually picks up. Although this year things are looking quite benign through mid-month.

Right now a very warm upper-level ridge is fading away, weak systems are pushing into the PACNW

A Pacific frontal system is getting organized offshore as cold air drops into the Gulf of Alaska under a developing upper-level low. Look at the change by Friday! That cold low has dropped down the central California coastline.

This gives us the "big rain event" of the week. Now through Friday afternoon, the GRAF model is showing up to an inch of rain in western valleys of OR/SW WA. Thursday is definitely an "indoor" day.

A secondary upper trough drops straight south out of Canada Saturday; it helps carve out a huge trough over the western USA. Las Vegas was in the mid 80s today, but only 50s by Sunday...

There won't be much rain with that secondary system so this weekend will be mainly dry; most likely some afternoon showers popping up Saturday though. In the Portland area, temperatures cool off from 60s today to upper 40s Saturday/Sunday. Back to normal and then below. The pattern remains cooler than normal through the middle of next week, here comes another upper-level trough dropping down along the BC coastline Tuesday. This typically isn't an especially wet setup, but cool

I expect at least a bit of snow in the Cascades the next few days as temps cool, but not a huge dump around Mt. Hood since snow levels will be relatively high through most of the precipitation.

At least it'll be a start, but I sure don't see skiing by November 10th.

So enjoy the rain tomorrow and refreshing/chilly weather over the weekend. Those leaves should be turning crunchy again by later Sunday/Monday as we dry out.

A new study shows that the deepest point on land is under the Denman Glacier in East Antarctica. Glaciologists at the University of California, Irvine, were mapping the area only to find that the trough under the glacier went far deeper than they had imagined.
