Heavy snow dumps up to a foot of snow in the mountains on Thursday; Denver in line for 3-7" of snow Friday night into Saturday

I only have time for a quick update, as I have been slammed at school for the past couple of days, and the ski slopes are calling my name this morning.  Heavy snow moved through the mountains yesterday, dropping about a foot for some areas, including Aspen, Vail, Breck, and Copper, with Loveland and A-Basin picking up close to 10 inches as well.  Skies are clearing this morning, but a sharp cold front associated with the next system will arrive tonight, bringing a band of heavy snow to the northern mountains initially... then, winds will switch to the northeast, and upslope snow will occur, bringing snow to the eastern foothills, Denver metro area, and eastern plains.

The models have not been getting a good handle on this storm for Denver, but for now it looks like there will be abundant moisture and favorable winds.  On the flip side, the system will be fast moving, which could limit accumulations.  Still, expect decent accumulations with periods of heavy snow.  Denver should pick up between 3 and 7 inches, while areas on the far eastern plains could end up picking more.  Areas in the foothills could receive up to 10 inches, as the higher elevation will help to produce more moisture, which in turn will produce more snowfall.

Sharply colder temperatures arrive with this system... highs in Denver tomorrow will stay in the 20's, with lows Saturday night possibly dropping into the single digits.  In fact, cold air will stay through the weekend, with highs on Sunday and Monday struggling to reach the freezing mark as well.  Wrap-around snow showers will develop Saturday evening in the northern mountains behind the system.  There will be a break on Sunday, then yet another system moves in Sunday night, bringing snow to the northern mountains, and possibly another round of upslope snow to the Denver metro area as well.  Snow showers continue in the mountains on Monday, then drier conditions finally move in by Tuesday.  March is living up to its reputation for stormy weather in Colorado this year, which given the drought conditions and low snowpack across the state, is a very good thing.
