KEY MESSAGES

- Elevated fire danger concerns will persist through Thursday due to very dry ground conditions and low humidity each day.

- Rain chances will increase across the forecast area this weekend.

DISCUSSION

Issued at 1244 PM CDT Mon Oct 26 2026

Through early next week:

High pressure will continue to be the dominant feature this week, supporting a continuation of warm and dry conditions. Deep mixing will allow for low RH to fall in the 20s and 30s. Despite fairly light winds, will maintain elevated fire danger in light of the very dry fuels and burn bans in many counties. Moisture will increase ahead of an expected shortwave Friday into Saturday which will limit fire danger, or even eliminate it for the weekend.

The aforementioned shortwave associated with the subtropical jet will be our next weather maker, and our source of rainfall for the first time in many areas in several weeks. It won't be a washout or drought busting, but may moisten fuels and provide short term relief. Total rainfall is forecast to be between half and one inch for most of the area with rain ending Sunday afternoon. Dry weather returns for early next week.

The polar jet aids in lee cyclogenesis off the Rockies early next week and at some point phases will subtropical jet energy, though guidance is varied on timing of this. The surface low will drag a cold front across our area around the Tuesday time frame and may give additional rain chances, however, confidence is low. /SAS/
