6 AM MST, Thursday, February 11, 2021
It has already been a cold week for the Front Range region, although for areas above 7000 feet, not really that cold compared to average. Friday through Monday will bring the most intense part of this cold spell, and the higher elevations will join in as well. Flurries with some minor accumulation are possible throughout, and a period of more steady accumulating snow is likely Saturday evening through midday Sunday.
At 6 AM this Thursday morning a gradient from cold to very cold lies across the northern plains and into northeastern Wyoming. That gradient will push slowly southward today and tonight. Today will be similar to the last few days, but will start trending colder from north to south this afternoon and evening.
Maximum temperatures Friday through Sunday will struggle to reach 20 in the lower foothills and plains, and on the coldest day (Sunday), temperatures may fail to reach 10. Minimum temperatures in the lower foothills and plains are likely to be 0 to 10 with some localized cold spots below zero Friday and Saturday mornings. But then widespread minimum temperatures below zero likely by Sunday and Monday mornings, with some local areas in double digits below zero on Monday morning. Although the worst of the cold should begin to let up Monday afternoon, it looks like we will continue to have below average temperatures through midweek.
Periods with clouds and flurries are possible throughout. But a distinct storm moving south of the Front Range region late Saturday and Sunday is likely to bring more organized areas snow, ending Sunday afternoon or evening. Accumulation of 3-6 inches is possible through Sunday, with most accumulation from Saturday evening through midday Sunday.
