KEY MESSAGES

- Strong to severe storms possible from late this afternoon and especially later this evening into the early Monday morning hours over the plains.

- Unsettled weather from late Monday into late week, then drier and warmer for the weekend.

SHORT TERM /THROUGH MONDAY/

Issued at 1230 PM MDT Sun Sep 20 2026

Main concern in the short term will be the likelihood of strong to severe storms affecting the plains from late this afternoon through early tomorrow morning. An isolated severe threat will occur mainly over northern El Paso county and possibly Kiowa county late this afternoon into early evening. A more substantial threat will develop form mid evening into early tomorrow morning over the plains as a strong boundary pushes across the plains assisted by a short wave at mid levels. 1000-2000 J/kg of CAPE and 40 knts of shear will be sufficient for severe storm development as the upslope flow develops after the front goes by. Large hail to 2", damaging winds of 60 mph and and isolated tornado will be possible. There is also a low risk of heavy rain developing over the Aspen Acres burn scar as the front pushes into the mtns. There is some uncertainty if convection will occur as the boundary hit the mtns/plains interface later this evening.

Showers and storms will last into the overnight hours and locally heavy rain will be possible over the far eastern plains during this period. Showers will likely still be going after sunrise tomorrow over the far eastern plains.

A brief reprieve in precip is expected tomorrow afternoon and early evening, but another round of showers and storms develops tomorrow evening over the mtns/plains interface extending over the eastern plains. The storms are not expected to be strong tomorrow.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/

Issued at 1230 PM MDT Sun Sep 20 2026

From Tuesday into Wednesday, another round of moist southwest flow will develop over the region, and this will bring another round of showers and storms to the region, with most of the heavier showers falling south of US highway 50. The overall best chance of more widespread heavier precip will occur wednesday afternoon with a heavier band of precip over the far eastern plains Wed evening.

Thursday and Friday will remain unsettled over the region with scattered showers and thunderstorms expected during the two day period.

For the weekend, it will be drier and warmer, with only isolated showers and storms expected. Temps for the weekend will be in the mid 80s plains and 70s valleys.
