Friday, July 30th, 3:50 P.M. 

Happy Friday!

Clouds and a smoky haze kept today a bit cooler than expected, but it was still very warm with highs making it into the mid 90s around the metro area. We are seeing some showers on the radar, but most of the rain is very light and evaporating before it hits the ground. A chance of thunderstorms or light showers will linger tonight, especially over the Cascades.

Saturday brings more high clouds and a smoky haze above with highs in the low 90s. Expect that smoke to stick around on Sunday, but it should have little to no impact on our air quality.

After a couple more 90 degree days on Monday and Tuesday, things cool off midweek. Thursday and Friday bring our first decent chance of showers in over a month and a half!

Today felt more like Memorial Day than one day after St. Patrick’s didn’t it?  EVERYONE west of the Cascades made it into the 70s with numerous record highs set for March 18th.

Todays Observed Highs OrWa 2017

That’s everyone except the Portland metro area.  Portland sure sticks out doesn’t it?  More on that below.

At least three records were set or tied

Most likely a few additional records were set at cooperative observing stations, but those records don’t show up until after the month is over.

Here in Portland the strong offshore wind flow brought widespread gusts 30-45 mph.  PDX had a peak gust to 40 mph during the afternoon hours.  I drove from Amity all the way up through Forest Grove and then Beaverton this afternoon.  That was after a couple of school visits.  Gusty northeast wind was blowing the whole way.  When you see it widespread like today, that’s a good indication it’s coming right over the Cascades and not just through the Gorge.  That will be the case again tomorrow.  Notice how widespread the wind was at 4pm

WIND CURRENT METRO ZOOM

In the metro area, strong easterly wind kept temperatures “down” a bit.   Mid-upper 60s closest to the Gorge to lower 70s farther away from that “cool” air.

PDX Observed High Today

That’s why PDX is always a tough forecast in this pattern both spring and fall.  Too much wind and temperatures don’t reach their full potential.

What’s ahead?  More of the same Tuesday.  The airmass warms slightly, and highs move uphill a bit east of the Cascades too.  That means we could have lots of mid 70s again tomorrow.  Portland will see just as much wind tomorrow so I figure maybe 2 degrees warming at PDX.  We should finally hit 70…just barely.

Wednesday will likely be Portland’s warmest day as east wind dies down in the afternoon, eastern Oregon temperatures warm further, and thick cloud cover stays to the south across southern Oregon.  We could get as warm as 75 Wednesday, but 73 seems like a safe call for now.

Thursday we’ll see partly cloudy skies with no offshore flow = back to more typical highs around 60.

Enjoy the warm sunshine!

This month (through the 17th) has seen an average temperature of 37.6 degrees in Portland; the coldest first 17 days of February in 28 years!  That was the year we had a HUGE arctic blast the first 10 days of the month.  We saw a HIGH of 15 early in the month as the arctic air came blasting in.  This month we didn’t get an arctic blast, but it’s been consistently chilly the past two weeks.  And that is going to continue for at least 7 more days.
