Damp & Cool

 

Typical pre-Spring weather on tap.  Keep that morn’n bev hot, as it will be chilly.

 

A cold-core Low, just off the coast of OR, is spinning its way south into CA.  Cool temps will follow, esp for Sacramento Valley (pockets of frost possible).  The PNW will be jacket-chilly this weekend and dry.  

 

The next chance for showers arrives sometime Tue, when a cold Yukon High begins its journey into the lower 48.  This cold air will clip the PNW just a bit by Wed, as the bulk of the cold will move east of the Rockies.  Still, a quick shot of Fraser Outflow should happen by early Wed, so Patrons in NW WA can expect a chilly, windy day mid-week.  (We do not foresee a deep freeze pattern, just cooler than the past several days.)  Also, the moisture associated with the cold front will fall primarily over NW WA on into ID, with a few showers possible from Salem north.  By Wed night, it will dry out again and stay that way until Sat Mar 12.

 

The weekend of Mar 12,13 is trending wet, esp by late Saturday.  A moisture-laden system will expand from Vancouver Is & environs to all of the PNW by Sunday.  Breezy.  Moderate rainfall will continue over central/southern Willamette Valley Monday.  Turning showery on Tue, the 15th over western WA & BC, drying out in western OR.  Looks like we’ll be in between systems for a few days to end that week.  On the latest charts, St Patty’s Day looks mild & dry, esp from Olympia south into northern CA.  However, that may be an outlier for now.  Stay tuned.  North Vancouver Is. will continue under clouds & showers during that same period.

 

Steady rain returns by Sat Mar 19, as a wet storm arrives from the west.  A second system may follow right behind that storm to contribute to a wet March weekend.  Overall, tough time for those waiting to ‘work the ground’ with their tractors, as we don’t see a dry stretch just yet.
