Going Dry

The PNW will be in a dry pattern for several days, after the current storm passes by.  Here’s a look at the latest outlook for the 2nd half of Oct.

Rain & breezy today, with showers and/or thunderstorms developing later this afternoon.  Tue will be a transition day into the dry spell, as High pressure builds over the region.  Temperatures mid-week will rebound to 70+ in several west side locations; a tad cooler around the Puget Sound, as the ’tail’ of a system keeps clouds and rain possible over Vancouver Is until Thu.  The coming weekend has been trending dry, but there are a few model solutions suggesting clouds and widely scattered showers on Sunday.  This is iffy right now.  

The next wet system had been modeled to arrive as a ’slam-bam’ windy storm on Tue Oct 24th.  That could still verify.  However, recent model scenarios track that deep Low west of the OR coast and south into CA.  Were this scenario verify, SW and SE OR could get some showers and/or thunderstorms as the moisture wraps northward around that Low.  Nearly all of CA would get rain.  COOL & dry for western OR & WA; damp over SE OR & ID. 

We’ll need to wait for models to, hopefully, consolidate a solution for the 24th storm.  Whether or not that system comes onshore over OR or south into CA, the weather afterwards is trending DRY and cool for the PNW through the weekend of Oct 28,29.  FOGGY bottoms, at times, for the usual locations, such as south of Salem, etc.

For the very end of the month & Halloween - possible showers & cool conditions.  Heavier rain storms are modeled to track into the Alaskan Panhandle.  Overall, the PNW looks rather dry for most of the 2nd half of October.
