Forecast Discussion:

With a storm underway this morning, I'll post midday as the storm is winding down with some initial observations and storm reports. We'll also begin to look at the Thursday/Friday storm that, right now, looks fairly small as snowfall amounts go.

Update 2:30pm Sunday 1/21

The storm is beginning to wind down in Longmont at this time.  Figure 1 is the snowfall reports at 7am today.  Most of Longmont received about 2 inches at that time and my yard has picked up an additional inch beyond that.  We did have freezing rain beforehand which made cleaning the car off difficult this morning.  We'll dive into the week ahead in tomorrow morning's discussion!
