Time and Day: 0930 Monday
The Snapshot: Dry today and tomorrow with increasing clouds.
Light mixed rain and snow on Wednesday, snow
and colder temperatures finish out the week.
The Science:
Temp = 39f, Rh = 47%,
barometer = 1021mb and steady, winds = gusty 10-15 E.
Nice daytime temperature
recovery will continue today and tomorrow with a cooling trend beginning on
Wednesday. The pressure/temperature gradients along the Cascade Crest that are
producing these gusty easterly winds will begin to ease today with NW flow
filling in tomorrow.
The high pressure that
produced this amazing weather as of late will begin to weaken and drift
offshore over the next few days. This will
open the door for a pattern change to develop.
Cool unstable air sinking in from the north will allow a few weather systems
to drop in from the north as the week progresses. There will be snow associated with this new
weather pattern, but because it is coming from the north interior, (cold with
low Rh’s) it won’t likely pack a ton of
moisture.
As for snow, it is a bit
early to have much confidence in the
models; but as of now, there will be a few inches Wednesday night into Thursday
with an additional 4-8” on Thursday and Friday.
Those values will likely change as the models begin to come into
agreement.
The Long Range: The weekend is trending dry, clear and cold. Low
temperatures could be in the teens through the weekend.
