KEY MESSAGES

Updated at 1030 PM CDT Sun Oct 4 2026

- Dry, warm weather, but lower humidity, is expected through Friday.

- Rain is expected to develop in the area again next weekend, with chances for thunderstorms (20-30%) on Saturday.

NEAR TERM

(Today) Issued at 313 AM CDT Mon Oct 5 2026

Low clouds have dropped south of the TN River as a canopy of high clouds persists. These will shift southeast through the day, with a clearing trend anticipated around Midday into the afternoon hours. North to northeast flow will advect dew points in the lower 50s once this clearing takes place. High temperatures this afternoon will reach the lower 80s in valley locations, with upper 70s atop the higher elevations on the Cumberland Plateau.

SHORT TERM

(Tonight through Wednesday night) Issued at 1045 PM CDT Sun Oct 4 2026

The Short Term portion of the forecast will feature a low- amplitude trough continuing across the eastern CONUS, while the old frontal boundary tends to stall in the Gulf region. While the upr trough will hold sway across the northern tier states and in the Grt Lakes, a broad sub-tropical ridge will tend to maintain a presence off the East Coast. This will allow for a mix of air masses across our area, both with a maritime and continental influence. This will result in lower dew point temperatures than what we have experience in recent days, but warm daytime temperatures will still be present. Dew point temps will tend to be upper 50s to lower 60s through the period, while daytime temps will still manage to rise well into the 80s both Tue/Wed. Being largely under the influence of high pressure, dry weather is anticipated for the period.

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
