Key messages

Issued at 818 AM CDT WED OCT 28 2026

- Fire Weather: There is a medium fire weather risk through Friday due to dry fuels and limited moisture.

- Halloween Evening: Rain chances will increase into the weekend. Whether the rainiest weather holds off until after trick-or-treat hours is unclear at this time, but you should at least plan for rainy impacts.

Discussion

(Wednesday through next Tuesday) Issued at 1131 PM CDT TUE OCT 27 2026

Over the next few days, upper-level ridging will continue to break down as a broad trough begins to establish itself out west. Due to this broad troughing pattern, flow aloft will transition back to the SW, allowing for moisture to return to the airmass overhead. As we get closer to the weekend, a weak system will begin to work into the central Plains, with a series of leading impulses branching off to the south. It's these disturbances that will allow for rain to return to the forecast through the weekend, with the bulk of the rain falling on Saturday, and low rain probabilities lingering through Sunday.

The new workweek should start on the dry side, with no additional rainfall expected through Tuesday. With that being said, long- range guidance has been consistently highlighting a broader pattern breakdown towards the middle of the week. While the exact impacts from this pattern breakdown remain to be seen, current guidance suggests additional rain activity, and a swing back to much colder temperatures.

Fire weather

Regional high pressure will carry our rain-free weather through Friday. MinRHs will be as low as an upper 20 to low 30 percent range through Wednesday. Increasing dew points starting Thursday will nudge MinRH farther above critical thresholds. Rain is likely over the weekend, with the brunt of activity favoring Saturday night.
