DISCUSSION /Through Monday/

Issued at 1106 PM MST Mon Nov 2 2026

Current radar shows rain showers ongoing for most of the plains with the heaviest rain over western Morgan County and eastern Adams County. Some light snow is occurring for the mountains, mainly north of I-70. With deep northerly flow still in place, rain/snow showers will remain possible through early Tuesday morning. For the high country, we expect very little additional accumulation of snow (perhaps an inch or two at most), so the Winter Weather Advisory was cancelled earlier this evening. Some light rain showers will remain possible for the Palmer Divide, eastern plains, and into most of the Denver metro. High-resolution guidance (including one of the last NAMnest and NAM runs) shows an additional 0.1"-0.2" of rain possible for western Washington county and adjacent areas with some isolated slightly higher amounts possible through the overnight. The chance remains for some snowflakes to mix in for the Palmer Divide to as far north as Akron as well as far northern Weld County given the decreasing snow levels. A dusting is possible for the Palmer Divide due to a trend of slightly lower snow levels tonight. The chance for precipitation should end between 6am and 9am Tuesday.

Gusty winds remain likely on the plains for the next few hours with some gusts of 50-55 mph still possible. Given the gusty winds, there is a near zero chance for fog this morning in northern Colorado unlike the last several days. Wind gusts of 30-35 mph will remain possible on Tuesday afternoon for the eastern plains. Otherwise, Tuesday will be a temperate day and feature warmer temperatures and more sun than Monday with upper-level ridging in control for our area. Highs should reach the mid 50s for the plains.

Wednesday brings the next storm system to our area, but it will move through quickly. A trough is forecast to move across Colorado from Wednesday afternoon through early Thursday. This system will lack in moisture, so any precipitation looks light in nature. Areas of the high country along the I-70 corridor and south look to be most favored for any light snow accumulations. Ensemble guidance is in good agreement that these locations should receive 1-3 inches of snow with perhaps some localized higher amounts at the highest elevations. DESI probabilities currently show that the chances for the heaviest snow in our area will be in the Mosquito Range. Some light rain showers will be possible for the Palmer Divide and our southeastern counties with an upslope component as the trough passes. The rest of the plains should stay dry. Any precipitation looks to quickly end on Wednesday night.

From Thursday onward, ridging builds into our area once again. A trough could move through the upper-level flow to our north on Friday. For now, we expect any meaningful precipitation chances to remain north of our area as moisture continues to be lacking. Guidance is in better agreement that another trough should move in from Canada down into the Great Plains just to our northeast towards the end of the weekend. This could introduce some gusty winds on Sunday for the eastern plains if momentum transfer is maximized as winds aloft could be rather strong. Otherwise, Thursday through Monday looks dry for our area. Temperatures should remain near average- in the upper 50s for the plains- through at least Saturday. The ridge look to strength and build into our area for Sunday and Monday, so temperatures could even reach the low to mid 60s for the plains on these days.
