...Moderate to Heavy Wet Snow Expected Late Monday Morning through 
Tuesday Morning...

.Snow levels have risen to about 4,000 to 5,000 foot elevations
this afternoon. Precipitation this afternoon is lifting westward 
more toward the coast, so the current round of snowfall in the
mountains will taper off.

Late Monday morning into the afternoon a strong and wet frontal
system along and near the coast will move inland with high
precipitation rates and snow levels falling into the 3,000 to
4,000 foot range. A period of heavy, wet snowfall is expected
across the area, likely resulting in impacts on area roadways,
especially during the Monday afternoon and evening commute.
