KEY MESSAGES

Issued at 629 PM CDT SAT OCT 17 2026

- Fall Weather: Cooler temperatures and breezy conditions are expected through the weekend.

DISCUSSION

(This afternoon through Friday) Issued at 117 PM CDT SAT OCT 17 2026

Stiff north winds will continue to usher in cooler temperatures behind the cold front, as a beautiful weekend remains in store for us. Afternoon highs will remain in the 60s, with overnight lows dropping into the low to mid-40s. The aforementioned winds will generally begin to decrease through Sunday, remaining from the N/NW for much of the upcoming week.

By Monday, temperatures will begin to slightly rebound, as upper- level ridging slowly starts to build off to our west. Thankfully, this climb will be gradual, with afternoon highs settling into the upper-70s and low-80s by the middle of the week. By Wednesday, the region will transition into NW flow aloft, as ridging continues to build to our west, and a deep trough takes shape to our east. While this NW flow won't affect high temperatures, it will keep dry air working into the area, with decoupled surface winds overnight. This will result in overnight lows continuing to fall into the mid to upper-40s through most of the upcoming week. Little to no rainfall is expected the next seven days as well, given the aforementioned lack of deep moisture in the overhead airmass.

FIRE WEATHER

A much drier air mass will build into the region this weekend behind a cold front and will persist through the upcoming week. Winds will be strong through much of today, with 20ft winds in the 10-15 mph range and gusts up to 25 mph. An abundance of dry air aloft will allow for thorough mixing, with MinRH values generally dropping to near 30% into the middle of next week. Given these low MinRH values and drying fuels, fire weather concerns will remain Medium for most of next week.
