Raindrops Quit Falling on my Head

Obviously, around the PNW, Summer months are supposed to be dry, yet a good rain here & there is refreshing (the last general rain was June 14).  The rainy weekend that some model solutions projected for the first weekend of August has been shifted a few days later - if at all.  Anyway, let’s take a look.

• July 25 - Sunday the 27th:  Pleasant weekend ahead - temps will be tapped down a few degrees as an onshore flow, under a cool upper-level Low, passes over southern BC.  Sunday will likely be the warmer day.
• Next week, July 28 - Aug 1:   Given a S-to SE flow aloft, it will heat up again early in the week, with humidity bumping up, as well.  The pattern also brings on afternoon thunderstorms over the eastern basins and the Cascades.  Some of these storms could migrate out over the western valleys.  Most of this action, if it develops, will take place Wed-Fri.  Idaho may also pick up a storm or two.
• Weekend of Aug 2,3:  Now trending warmer than the previous week.  Thunderstorm threat diminished.
• Week of Aug 4-8:  This is when models are bringing down some moisture out of the Gulf of Alaska - MAYBE.  Temps will be warm early in the week, with the chance for rain - mainly over western WA - arriving Tue night on through early Fri.  OR could pick up some raindrops Thu and/or Fri.  This whole pattern change is quite uncertain.  
• Weekend of Aug 9,10:  Dry with pleasant temps on Sat; turning warmer Sunday.  Region could be setting up for another hot spell that next week.

—> The primary aspect of this long-range forecast is whether or not the PNW gets raindrops from a Low pressure system that may move close to the west coast from the Gulf of Alaska.  Right now, we are going to call it a ‘coin toss’ — 50/50 chance.  Otherwise, raindrops won’t fall on anyone’s head.  Stay tuned, Patron.
