One More Damp Week

 

The longest day for daylight is still a couple weeks away, but for today, we collectively remember that monumental event is 1944.  Our wet Spring will continue for another week or so.  Here’s the latest outlook.

 

It will turn dry & mild starting later this afternoon and on Tue.  The next quick short-shot of limited precip set to arrive overnight Tue.  Wed should be another dry day before, sadly, yet another round of rain could arrives sometime on Thu.  Models differ as to the extend of the rainy period starting this Thu on into the weekend; some train the moisture up over NW WA and BC, others target moderate rain over the northern half of western OR, as well.  Either way, the event could be one for the ‘books’, as the amount of precipitation could break records for a June storm, depending on just where that ‘jet stream’ and subtropical moisture streams onshore.  If it tracks mainly into WA, OR conditions will be on the warm side & dry.  For Patrons in farm country north of Seattle, yikes, another drenching. 

 

Across the PNW, this coming weekend should be the last 2 damp days before a dry spell develops.  High pressure over the Gulf of Alaska may finally start to replace that broad trough of Low pressure (as we discussed last time), setting up a cool, but dry, onshore breeze (quite strong at times) for the period of Mon-Fri, Jun 13-17.  The weekend of June 18,19 may experience a few showers by Sunday evening, but right now, that weekend charts as dry, mild.

 

As the Summer Solstice (Tue Jun 21) approaches, a cool Low pressure zone may work its way south along the inland passage, setting up cloudy days and possible showers by late Wed or Thu, Jun 22,23. 

 

Overall: unfortunately, a generally wet period remains on the charts for the next week before the PNW may finally catch a dry break.  We sure hope so.
