Forecast Discussion:

NOTE: The snow reports will be included in tomorrow's post (March 15).

I'll post this now and update with snow/rain reports in the morning.

The giant low that deepened in Colorado and moved on into Kansas (Figure 1). By about 11am the atmospheric pressure had dropped 34mb over southeast Colorado. Wind speeds seen up through midday were impressive (Figure 2). There still will be about 1-3 inches of snow to fall as the system winds down (and down slope flow starts to matter). It should be all over in Longmont before midnight (this was posted at 4pm Wednesday).

The longer range forecast:

We warm through the 40's F by the weekend, the 50's by mid-week next week, and touch 60F by the end of next week. Nice.
