The warm before the storm as Thornton will be mild Tuesday, snow arrives tonight

Tuesday, February 21st, 2023 5:13am MDT

As is pretty typical for this time of year, we enjoy some ups and downs, all within a short period of time. Today will be mild but our next winter storm arrives tonight with snow and, more notably, some very cold temps.

For today, there will be varying levels of cloudiness but overall, look for partly sunny skies. Winds will be slightly breezy but less so than the last couple of days. High temperatures will top out close to the 60 degree mark.

Tonight, cloudy skies will be overhead with lows in the teens. A rain / snow mix may develop by about 10:00pm changing over to all snow after midnight. Only minimal accumulations are expected overnight.

Tomorrow, the storm system arrives in earnest and we can expect snow throughout the day tomorrow. Late afternoon will see it begin to taper off, ending after dark.

A Winter Weather Advisory will be in effect with the National Weather Service calling for 3 to 6 inches. The potential is there for those amounts, however, models are not really in agreement on this one. The foothills and areas north are likely to bear the brunt of it. For Thornton, we tend to think we will be at the lower end of the totals seen.

More than the snow will be the cold that is coming. Highs tomorrow and Thursday will remain below freezing with lows tomorrow night and Thursday night getting extremely cold. For more, see here.
