Snowy/colder Saturday afternoon & night, light snow Sunday

12:15 PM, Saturday, February 21, 2015

As expected, most of the Fort Collins to Denver corridor received minor accumulations (Trace-3 inches) through 7AM.  There were some local exceptions, most notably the Broomfield-Westminster area where 5-10 inches fell.

A strong cold front just crossed the Cheyenne area at noon and should move down the Front Range this afternoon. Temperatures will fall and snow will likely become more steady and perhaps reach moderate or heavy intensity at times late this afternoon or evening. The snow is probably going to decrease in intensity Sunday morning and become more intermittent. The exception is the Front Range south or Pueblo and the mountains south of I-70 where moderate or heavy snow may continue at times into Monday morning.

FOR THE CHEYENNE-BOULDER-DENVER-COLORADO SPRINGS CORRIDOR:

Turning colder with snow becoming more steady and roads getting icy during the afternoon and into the evening. Snow intensity decreasing Sunday morning, probably before daybreak north of I-70. Some intermittent snow is likely, especially near the foothills Sunday afternoon and night. Temperatures will likely fall to with a few degrees of 10 tonight, stay around or just below 20 Sunday, and fall to between 0 and 10 Monday morning.

Most likely additional accumulations Saturday afternoon through Sunday morning:

4-8 inches Cheyenne, Fort Collins, Longmont, DIA.

6-10 inches Boulder, Broomfield, Denver & its west and south suburbs, Colorado Springs.

8-16 inches foothills, mountains, Palmer Divide, heaviest most likely south of I-70.

Most likely accumulations Sunday afternoon through Monday morning:

an inch or less in Larimer and Weld counties, and the Cheyenne are,

1-3 inches in the Boulder-Denver-Colorado Springs area.There is a small chance that more substantial snow will re-develop late Sunday (greater than 3 inches), but it’s probably only a 20% chance, even less north of Boulder County.

NEXT ROUND

We probably won’t have a chance to melt out this snow before the next cold front and snowfall arrives late Wednesday or early Thursday.

BOULDER FEBRUARY RECORD:

As of 7AM the February snowfall total in Boulder is at 24.2 inches. Another 8.0 inches would establish a new February record. Between this weekend and the next snow likely Wednesday night, that seems very reachable.
