Short term...tonight through Wednesday...high pressure is building
over the region and will continue to intensify over the region
through the short term. This will lead to a developing low level
inversion which will begin to trap moisture in the form of fog and
low clouds around the lower Columbia Basin and some mountain
valleys. Some of this could begin to form overnight and then mostly
dissipate on Monday. But as time GOES on the dissipation will be
less and the fog will become more persistent. Temperatures above the
inversion will run above normal while below normal beneath the
inversion.



Long term...Wednesday night through Sunday. Mainly dry and mild
conditions will persist through Thursday. On Friday the ridge will
be shifting east as a trough of low pressure moves to the coast with
a chance of rain spreading east of the Cascades. There will
continue to be a chance of rain Friday night with mountain snow
through Saturday as snow level lower to near 5500 feet. The
unsettled conditions continue through Sunday as another system
pushes through the ridge. Temperatures will be mild through middle
week and then cool to near seasonal levels through next weekend. 93

Aviation...00z tafs. VFR conditions will prevail at most locations
through the next 24 hours. Middle and high level clouds will continue
across the region tonight and Monday as a ridge of high pressure
builds. Overnight with the light winds and some low level moisture
