An Adjustment

A cooler wx pattern is now in place around the PNW.  Let’s look ahead for the rest of June.

We noted in the last report that the balance of June 2025 was charting as pleasant & dry.  An adjustment in that outlook is now charting to begin later next week, as the chance for some precipitation has been added to the forecast.   A rather stationary upper-level Low has been parked over the Alaskan Panhandle, ushering in the onshore flow, morning marine clouds & cool temps that we are experiencing now.  This should hold through the weekend and through Tue Jun 17.  

It looks like that Low will slowly shift farther south, opening the door for slightly cooler temps, more cloudiness and showers, esp for the Puget Sound.  Wednesday the 18th could present such a change, with western OR getiing in on the action as next week ends.  The Summer Solstice - next Friday Jun 20 - looks generally dry, but with the chance for a few stray showers.  

The weekend of Jun 21,22 currently charts as mostly dry, but cooler than normal for June.  For this forecast, we will emphasize that Mon & Tue Jun 23, 24, could be the wettest period between now and July 1.  

It’s understood that all of the above could change, depending on the position of that upper-level Low - so keep your Mug handy for updates.
