A strong cold front along the Front Range Tuesday morning will turn the temperatures notably colder once again through Wednesday night. There may be some light intermittent snow tonight, but it probably won’t amount to much. Then, after the cold front early Tuesday, low clouds should develop followed by widespread snow. The best period for accumulating snow is late Tuesday into early Wednesday morning
Nederland, Evergreen, Monument: 4-8 inches.
Cheyenne, Boulder, Broomfield, Denver’s west and south sides: 3-6 inches.
Fort Collins, Longmont, east side of Denver, Colorado Springs: 1-3 inches.
With the current storm I see very little chance of widespread heavy snow surprising us (~10%). If anything, there is about a 20% chance that the amounts will be lower than those given above.
It will continue snowy in the western mountain areas today through Tuesday (some rain in the valleys), so expect winter travel conditions, especially at the passes along and north of I-70.
Temperatures are likely to fall into the teens after the cold front tomorrow morning. The record low Wednesday morning in Denver is -3 (1978). In Boulder it’s -1 (1960). Both are likely to hold since cloud cover will reduce the chances of falling below zero. Temperatures are likely to climb above freezing and Thursday and Friday. It’s unclear at this time whether another cold front this weekend will interrupt the warm up. But overall it appears we are transitioning into a milder pattern.
