KEY MESSAGES

Issued at 1236 PM CDT SUN OCT 18 2026

- Seasonable Weather: Seasonable temperatures are expected for most of the next seven days.

DISCUSSION

(This afternoon through Saturday) Issued at 1236 PM CDT SUN OCT 18 2026

Very seasonable weather is expected for most of the next week, as upper-level ridging continues to slowly build off to our west. This will still allow for afternoon highs to slowly climb a few degrees, generally stabilizing in the mid-70s and low-80s by Midweek. Around this same timeframe, the flow aloft will begin to transition into a rather interesting shape, as the ridge begins to get "pinched" by a deep trough to our west, and to our east. In turn, we'll get placed into this north flow regime that will allow for cooler air to filter down the Appalachian mountain range. Afternoon highs will generally be unaffected through the week, but overnight lows will be slightly cooler for this time of the year, as radiational cooling is expected from a lack of winds. Closer towards next weekend, this north flow will slightly shift to the NE, which will then allow for our highs to take a dip. Under the influence of this NE flow, highs in the east will range in the low-70s, where highs in the west will range in the upper-70s.

Given the ongoing lack of moisture depth in the air column overhead, and lack of a solid forcing mechanism, little to no rainfall is expected over the next seven days.

FIRE WEATHER

The dry air mass will persist through the upcoming week, with 20ft winds stabilizing to near 5 MPH during the day, and peak gusts between 10-15 MPH at their strongest. The 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.
