Time and Day: 1000am update for Friday
No significant changes to this morning weather
forecast:
There is a nice band
moisture moving through the southern portion of the state. Stevens is getting some nice spin-off showers
from this. The snow showers will become
less frequent through the day. Other than the obvious
slight increase in snow amounts, all details remain the same as earlier
forecasted.
Enjoy.

Time and Day: 1000
Friday
The Snapshot: Light snow today, dry and cold tomorrow, new
snow for Christmas.
The Science
Current Observations: It is lightly snowing with a temperature of 260f
in the base area and 23f on the upper mountain. The RH is 93%
and the barometer has bumped up a notch to 1016mb’s. The winds are light
and out of the west. Satellite imagery has light precipitation starting
to pop up around the
state.
The Forecast: The light snow is a product of a weak low-pressure
trough sinking in from the north. Most of the activity is centered over
Oregon which equates to just a few light snow showers with some clear periods
for the North Central Cascades. Tomorrow will be mostly dry with some
clearing before next low-pressure system moves in on Sunday.
Early calculations have
Sunday’s storm producing 4-8” of snow. Confidence in that detail is still
a bit shaky.
The Long Range: The precipitation moves out on Christmas day
with the first half of next week trending dry
