Snow by Tuesday morning

11:15 AM MST, Sunday, November 22, 2020

Today through Tuesday

A relatively fast moving but organized storm system is likely to bring some light to moderate snow accumulation Monday night and early Tuesday, mainly in the Denver-Boulder metro area south to the Palmer Divide region.

First we will see a warm-up on Monday with afternoon temperatures in the lower elevations reaching the 50s to around 60. As the storm first begins to impact the Front Range region Monday night, there is a good chance it will be rain below 6000 feet, but snow at all elevations by morning. Snow is likely to end during the day Tuesday.

Potential accumulation:

For areas north of a DIA-to-Lyons line the accumulations are probably going to be very minor if any (trace to 1 inch).

South of the DIA-to-Lyons line (including Boulder, Broomfield, Lakewood, Denver, Castle Rock) there is likely to be 1-3 inches, and because the storm’s organization is increasing with time, I think there is about a 1-in-3 chance for 3-6 inches. South of the Palmer Divide in Colorado Springs the chance for 3-6 inches is less.

Above 6000 feet a 6-inch storm appears likely, especially in Boulder, Jefferson, and Douglas counties.

Wednesday-Friday

After a seasonably cool and dry Wednesday and Thanksgiving Day, the next chance for snow (probably light amounts) will probably occur sometime between Thanksgiving evening and early Friday. Dry weather is likely to be with us for the remainder of the long weekend.
