Just when you thought spring had arrived, Denver’s weather is about to take a sudden and icy turn. After enjoying mild temperatures in the mid-60s°F (around 19°C) to begin the week, a powerful cold front is expected to crash the party, bringing plunging temperatures, gusty winds, and even the possibility of snow.
If you’ve packed away your winter gear, you might want to dig it out. Forecasters predict that by Friday and Saturday, temperatures will barely reach the 40s°F during the day, with nighttime lows in the low 20s°F (-5°C).
Snowfall is becoming more likely, particularly in the foothills and surrounding suburbs, with accumulations of 1-3 inches expected by the weekend. Denver’s unpredictable March weather is on full display, ranging from spring warmth to full-fledged winter in a matter of days.
What’s Causing This Sudden Weather Shift?
The cause of this dramatic temperature swing is a strong cold front moving in from Canada. As it moves southward, it will bring much colder air, causing daytime highs to fall by nearly 20°F in just 48 hours.
At the same time, moisture from the west will collide with the cold air, increasing the likelihood of snowfall, particularly late Thursday and Friday. The mountains and foothills are expected to see the most snowfall, but metro Denver may receive a light dusting or a couple of inches.
The main concern? As snow mixes with freezing overnight temperatures, road conditions will change quickly, and icy patches may form, making for slick commutes.
