Time and Day: 1030 Wednesday
The
Snapshot: Partly cloudy today and tomorrow with dry conditions
prevailing in the mountains through Friday.
The
Science: After a few
more days of fairly benign weather, the polar jet is expected to take aim at the
PNW. This will open the door for a
strong frontal system with abundant moisture to track through the PNW over the
weekend.
4-7day
Long Range: As of now, this is how it is looking like it will
play out: Light rain reaching the
mountains late Friday afternoon with freezing levels around 5000’. Freezing levels drop to 4500’ on Saturday with
mixed snow and rain. A strong cold front arrives early Sunday morning with
heavy snow in the mountains possible.
Of course, this is still a few days out so I will be watching this closely
as the timing and details become more clear.
High pressure begins to rebuild on Monday for
another prolonged dry period to start the new month.
