Key Messages

- Afternoon RH values will drop into the 25-35% range each of the next several afternoons (mainly in southern middle Tennessee and NW Alabama), creating the need for extra caution regarding outdoor burning.

Near Term

(Today) Issued at 255 AM CDT Sun Oct 25 2026

Overall, the forecast remains on track with no significant changes needed. Currently, temperatures are in the mid 40s to lower 50s with calm to light winds. Not anticipating that lows will to dip too much cooler beyond the mid to upper 40s over the next handful of hours. Haven't seen much fog formation via satellite imagery or surface observations yet tonight, but there still remains at least a low chance in the river valleys, sheltered locations, and next to bodies of water through early this morning.

The forecast for today remains unchanged as well. Expect mostly clear skies with highs topping out in the lower to mid 70s for most locations. In addition, model guidance (and recent trends) indicate that dew points will be lower (in the 40s) for much of the afternoon leading to minimum relative humidity values in the 30-40% range for most areas. However, there is potential for some locations to dip further into the 25-35% range. With light winds, Red Flag conditions are not met; but, regardless, please exercise caution with any outdoor burning.

Short Term

(Sunday night through Tuesday) Issued at 1010 PM CDT Sat Oct 24 2026

A slightly less amplified upper ridge remains over the area Sunday night into Monday. 925 mb temperatures again don't look much higher, despite abundant sunshine. Low level easterly flow may again be the culprit. Thus, keeping highs in the 70 to 75 degree range again. Dewpoints were lowered slightly, a degree or two below Conshort, but afternoon mixing does not look too impressive.

By Monday night through Tuesday the center of the upper ridge moves east and is centered closer to the area. This will likely allow for warmer temperatures, allowing highs to climb into the mid to upper 70s again. Afternoon mixing may be a bit more potent by then, but too far out to lower that much yet in the grids.

Long Term

(Tuesday night through Saturday) Issued at 1010 PM CDT Sat Oct 24 2026

The ridge will temporaily flatten on Wednesday as a dry front ripples across the Mid South/Ohio Valley, bringing some cloud cover to the area. However, given the very limited moisture, no precipitation is forecast and some limited heating will still push highs into the 70s. No air mass modification will occur behind the front (save for a reinforcing shot of drier air). In fact, a gradual warming trend will take place late next week as an upper ridge axis centered over the northern Gulf amplifies northward into the Tennessee Valley and winds veer to the SE/SSE. Highs will climb into the upper 70s on Thursday and the lower 80s in most locations Friday and Saturday to close out the month.
