Monday
The Snapshot:
Welcome
2018, may you be filled with deep light
powder.
It will be mostly dry
today with base area fog. You may have to go to the upper mountain if you are in need
of sun. These dry conditions will continue
through Thursday with light mixed rain and snow expected Friday/ Saturday.
The Science
Current Observations: It is clear
on the upper mountain with fog at Pass level.
The base temperature is 16of,
the RH is 94% and the barometer is holding steady at 1023mb’s. Satellite imagery has a low level stratus
cloud layer nestled up against the east slopes of the Cascades and clear skies
to the west.
The Forecast: While a dome of high pressure brings sunshine
and warm temperatures to western Washington, the all too familiarly inversion
layer has formed in the eastern basin.
The inversion feature will likely continue through most of the
week.
The Long Range: The change begins late Thursday with mixed
rain and snow possible on Friday. A more
progressive weather pattern is expected for the weekend.
