The Temp Coaster

Wx for the rest of July will present fairly normal temperatures, with a nominal chance for precip in the northern portions of the PNW.  Let’s take a look ahead.

Hot temps for today through the weekend.  To start next week, a weak Low will drop in from the NW, ushering in a welcomed onshore flow with cooler temps and cloudiness, esp over Vancouver Is & the northern Puget Sound region.  After a couple of cooler days, the warm ridge of high pressure will again build in over the PNW, for another round of warm-to-hot afternoon temperatures during the second half of next week.  Up & Down.

For the July 22,23 weekend we can expect the dry summer pattern to continue.  Temperatures may cool down again by 10 degrees or so as another Low moves into position to offer a cool onshore breeze, with clouds and a slight chance for showers, mainly in the far NW corner of the PNW.   That will keep the door open for a stronger Low to moves into the region as the last week of July 2023 gets underway.  A much higher chance for showers is possible that week, including over NW OR.  We’ll see.  As you might expect, temps will remain on the cooler side of summer for the July 24-26 period.  By Thu the 27th, high pressure may begin to rebuild, as will the afternoon temps.  The temperature coaster goes up & down.

The final weekend of July is trending HOT.  This could be the warmest period of the summer, thus far.  Triple digits possible in locations west of the Cascades (think southern OR, Willamette Valley, eastern side).   

Summer monsoon action in the desert SW will kick-up considerably as the month of July nears an end, 'cooling down’ the regional heat wave in that area.  However, the major heat wave will cross into southern CA late July, as well, setting off notable power issues for the Golden State.  News media will go bonkers over this, spreading blame everywhere.
