0900 Wednesday:
The Snapshot: Today and tomorrow will rather
nice with sun breaks and warmer temperatures; winter returns this weekend with
some snow.
The Science: High-pressure
will begin to dissipate the clouds and warm up the atmosphere for the next few
days. The northern jet stream will then
take aim at the PNW with the potential for some measurable snow over the
weekend.
Storm Details: This system is
a few days out and still developing so details such as timing, precipitation amounts
and temperatures are still a question.
As of now, the leading edge of the first cold front is expected to reach
the west slopes late Friday night.
Strong westerly flow (convergence) has the potential to dump up to a
foot or more of snow on Saturday and Sunday.
Models begin to disagree with the track and strength of the following
low-pressure system developing on Sunday/Monday. Some have it tracking south with little
effect on Stevens. There is also potential
for warmer air to be pulled in from the southeast interior that could equate to
rain. The one time where east flow may
not be to our liking.
Long Range: High-pressure returns on Tuesday of next week for an end to the excitement.
