...HEAVY SNOW IN THE NORTHERN MOUNTAINS AND POSSIBLE IN SOME
NORTHERN VALLEYS...

.A wet and mild storm system will bring moderate to heavy snow
across the northern mountains starting Tuesday and persisting into
Wednesday. Snow levels will start off near valley floors Tuesday
and a persistent influx of warmer air will lead to rising snow
levels by Wednesday. Exact timing of the transition from snow to
rain and subsequent valley accumulations carries lower
confidence. Higher confidence exists for heavy accumulations in
the mountains.
