Another day or so before a long stretch of COOL DAMP wx begins. It
could be the second half of May before pleasant conditions return to the PNW.
Large upper level trough of cold air will drop over the PNW and usher
in COLD rain, showers, clouds, and the risk for FROST by the weekend.
Mountain snow, too. The rainfall will not be steady, but consistent
enough to block most ag work. It should dry out a bit by late
Fri/Sat, however, it will be CHILLY - if clearing takes place
overnight this weekend, esp east of Cascades, RISK FOR FROST will be
moderate. Point of reference: it was low-to-mid 30's in many places
this morning; next weekend, the air will be colder. Monitor your
local conditions closely.
Showers will diminish a bit late Saturday thru Monday before another
shot of cool rain hits (this time
mainly in Washington) by late Tues, May 9. Current prog charts hint
at a rather STORMY couple of days across the PNW May 12-14. Will that
be the end of the chills?
Warm break? Second half of May: positioning of the high pressure
ridge well west/southwest of the PNW may shift just enough to the
east to bring more seasonal, dry conditions to the PNW. Keep your
morning beverage cup handy, and we'll work on improving the wx.
California will get cooler wx, with showers/rain likely as far south
as Bay Area this week. Cooler in
southern Cal over the weekend. Middle of the U.S. will see VERY
STORMY conditions, as our cold front passes out of the west, into the
flatlands. Tornadoes probable.
