0730 Friday:
The Snapshot: Diminishing snow today, snow changing
to rain tomorrow. Windy and rainy on Sunday.
The Science: A weak upper-level ridge will pass over the region
today decreasing the precipitation. A
pair of warm fronts hit the mountains tomorrow with high winds, rising freezing
levels and heavy rain. This first front
will push a wave of moisture ahead of it with freezing levels at or just below
4000’. Once the second front enters the
scene tomorrow afternoon; the winds kick in, the freezing levels rise and the snow
changes to heavy rain. Sunday will start windy and wet with rain changing
back to snow and then tapering off by the end of the day.
4-7day
Long Range: Monday will be dry with more
mixed rain and snow possible on Tuesday.
The holiday week ends cool and dry.
