Snowy weekend on track

3:30 PM, Thursday, February 19, 2015

Widespread significant snowfall is expected Friday night through Monday morning in all mountain areas of Colorado and southern Wyoming, as well as most of the eastern plains. For the Denver-Boulder-Fort Collins area, there is one notable change from my blog yesterday. Although I still expect the snow to start Friday night, the best potential for heavy snow is late Saturday and Saturday night.

Timing: Snow begins (maybe a little rain in lower elevations at the start) late Friday afternoon or evening in southeastern Wyoming and northern Colorado, and by Saturday morning in the Colorado Springs area and spreads south from there on Saturday. Snow is likely to end by Sunday north of Boulder County but some snow may linger into Sunday night or Monday morning in the Denver Boulder area. Significant snowfall may still be in progress for the southern mountain areas into Monday.

Amounts Fri-Mon:

5-10 inches is likely north and east of a line from Laramie to Longmont to DIA to Limon, mainly by Saturday night.

8-12 inches In the Boulder-Broomfield-Denver-Colorado Springs corridor, heaviest near the foothills and Palmer Divide. The best chance of heavy snow is late Saturday afternoon and night, and then becoming lighter or intermittent by Sunday afternoon.

Mountains and foothills: 1-2 feet, with the heaviest in the northern ranges through Saturday night, and south of I-70 Saturday night through Sunday night.

February snow record: Three snowfalls in February have been highly variable, but the Boulder climate station collected 21.9 inches. That puts us only 10.3 inches away from eclipsing the February record of 32.1 inches set in 2012. And even if we don’t do that this weekend, it appears that another chance for snow arrives around Thursday next week.
