KEY MESSAGES

Updated at 903 AM CDT Mon Oct 5 2026

- Dry, warm weather, but lower humidity, will continue through Friday. Highs will reach the low to mid 80s and lows will drop to the upper 40sw to low/mid 50s.

- An area of low pressure over the Gulf may approach the MS/AL/FL Coastline this weekend, potentially bringing locally heavy rainfall to portions of the Tennessee Valley late Saturday into Sunday.

NEAR TERM

(Tonight) Issued at 109 PM CDT Mon Oct 5 2026

Clear conditions across the Tennessee Valley this afternoon as breezy NNE winds help to advect in a drier air mass into the region. Temperatures will reach the low to mid 80s over the next couple of hours, despite the northerly flow -- thanks to ample sunshine. However, by late in the day into the overnight hours, winds will subside, resulting in a clear/calm night. These conditions along with the dry air mass will again create a good setup for radiational cooling as temperatures will drop off quickly this evening -- eventually settling into the upper 40s to lower 50s by early Tuesday morning.

SHORT TERM

(Tuesday through Wednesday night) Issued at 903 AM CDT Mon Oct 5 2026

A large area of high pressure over the Ohio Valley will remain the dominant weather feature across the region Tuesday and Wednesday. Expect more of the same for the next couple of days: beautiful, autumn weather. With plenty of sunshine, daytime highs will reach the low to mid 80s each day -- and with RH values dropping to around 40 percent, it will feel quite comfortable outside. Good radiational cooling will occur each night, with lows dropping into the low to mid 50s.

LONG TERM

(Thursday through Sunday) Issued at 1045 PM CDT Sun Oct 4 2026

Dry conditions with above normal warmth for early October continues Thursday. Surface high pressure situated from the central Great Plains to off of the Mid Atlantic coast should bring an easterly flow across the Deep South. Under mostly sunny skies, warm temperatures will prevail with highs rising into the mid/upper 80s. This warmth will result in low afternoon relative humidities reduced into the mid 20s percent across much of the Tennessee Valley west of I-65. A forecast of light winds should help temper elevated outdoor fire spread risks. Similar warmth is forecast Fri with highs again climbing into the mid/upper 80s, with similar reduced mid afternoon relative humidities. Low temperatures both Thu/Fri night should cool into the 50s.

A forecast for the upcoming weekend is one of low confidence regarding rain chances. The models generally show moisture to our south moving further northward. Some of the models, especially the 12Z Canadian and 18Z GFS hint at a potential tropical system moving from the western Gulf of America, across the Deep South (including this region) Sat into Sun. The 12Z ECMWF kept it's tropical entity more over the western Gulf, with lesser moisture impacting this region. Many things could occur with the development of this system as we go through the week; something that'll closely be monitored.

AVIATION

(18Z TAFS) Issued at 1200 PM CDT Mon Oct 5 2026

VFR conditions will prevail through the period, with light winds and a mostly clear sky. Winds will be gusty out of the NNE/NE, before weakening to under 5 KT after sunset.
