.SHORT TERM...Tonight through Monday night...Cool northwesterly

valley rain showers. Snow levels fall to 3500-4500ft MSL by
Monday afternoon. Snow accumulations up to 2 inches on the

Monday will be around 10-15 degrees below normal. Windy
conditions expected behind the front on Monday afternoon, with
west- northwest wind gusts of 45-55 mph possible in the Magic

to issue highlights for this as confidence increases and the
event gets closer.

.LONG TERM...Tuesday through Saturday...A cool upper level
trough will remain over the area through Thursday keeping a
chance of showers, low snow levels, and temperatures 10-15
degrees below normal. Snow levels will be around 3500-4500 feet,
