Saturday Update: The Front Range Forecast: Snow Totals; Warm Up

In Brief:

Snow totals and much warmer soon!

Saturday Update:

The forecast, below, was a good one for Colorado. Longmont received about 1.5 inches (Figure 1 update) while boulder got 3-5.7 inches.  By Tuesday, we will be up into the 60's.  Watch it melt!

Ens Saturday update.

Forecast Discussion:

A cold front is on its way (it is parked near Cheyenne currently) for Friday. After a morning shot of light snow, snow or snow/rain mix chances begin to rise around 3pm and continue until after midnight Saturday morning (Figure 1). Much of Colorado will have snow chances with the front pushed up into the Rockies (Figure 2).

The weatherunderground model gives Longmont 1-2 inches of snow. The GFS gives us 1-3 inches with 3-5 inches in Boulder.  Snow totals increase quickly into the Foothills. The NAM 1-3 inches as well (Figure 4).

This doesn't look like a big or very cold storm.  Just a reminder that winter is still around.  You won't think that in the Longer Range forecast below...

The Longer Range Forecast:

The normal high temperature returns to the 50's in a week but actual highs will climb into the 60's!  There is a chance of rain or maybe snow towards the end of next week... more on that later!
