0830 Wednesday
The Snapshot: Today will be mostly dry with thickening clouds. Light snow with a chance of some freezing
rain will greet us in the morning.
Light precipitation with sun breaks can be anticipated tomorrow; snow on
Friday, Sat and Sun.
The Science: The cloud deck will thicken today as the high-pressure
ridge continues to weaken and drift east.
An occluded front will move onshore early tomorrow morning producing
some light snow and possibly rain. A
fast moving weak high-pressure ridge moves through tomorrow cutting off the
moisture and producing some breaks in the clouds.
Things get
interesting on Friday as the first in a series of strong frontal system ushers
in the first significant snow of the season.
Freezing levels will be around 4500’
to start, and then drop to 3500’ through the weekend. Heavy snow, with a little rain thrown in for
good base making, will start mid-day on Friday and continue through the
weekend.
4-7day Long Range: Light snow showers can be
expected on Saturday with another storm with more snow on Sunday. Storm totals from 4am tomorrow through 4am
Monday are currently= +2” of water = 12-24” of snow.
Longer range models show more systems on Monday and
Tuesday with freezing levels reaching 5-7000’ by Wednesday of next week.
