Spring has arrived. Temperatures this weekend will be at least
ten degrees above average. The next chance for rain looks to be
Wednesday and Thursday of next week with the arrival of a mild
Pacific system.

Discussion...
tonight through tues: the dry and very mild conditions will
continue, with only a few minor, non-eventful issues to address.
The first will be a brief breakdown of the upper ridge for
Saturday as a quick-moving short-wave trough clips the north Idaho
Panhandle. Based on the dry air-mass accompanying this feature, as
well as lack of sustained forcing for ascent, the outcome is
likely to be only some mid clouds close the British Columbia border. Behind
this front we see only modest pressure rises across srn British Columbia...which
may briefly produce some gusty north winds down the Okanogan
Valley Saturday. The upper ridge will strengthen again Sunday
through tues an advance of the next major frontal passage due by
Wed. This pattern favors some very brief gusty winds mainly in the
Cascade gaps Monday...then warm and dry wx Tue as the low- level
thermal ridge moves into ern west and north Idaho.

..we have the potential to see high temps close to record levels
Tue with numbers 10-15f above normal...bz

Tuesday night through Friday...an upper level low pressure center
will fling a couple of shortwave impulses across the inland
northwest for Wednesday into Thursday. Models are slowing down the
progression of the first frontal system, bringing precipitation to
the Cascade crest Tuesday night but not reaching the bulk of the
forecast area until Wednesday. By the time the first front exits
the Idaho Panhandle late Wednesday, the second system will be
coming into western Washington. A chance of precipitation will continue
through Thursday evening then drop off significantly as the upper
ridge rebounds over the region Friday. Snow levels will remain
rather high with snow expected only for the high peaks.
Temperatures will be a bit cooler than tuesdays readings but will
remain well above normal for mid March. Any breaks in the overcast
during daytime heating could result in some convective type
showers with some gusty winds. /Kelch
