KEY MESSAGES

Updated at 840 AM CDT Mon Aug 24 2026

- Low to medium chances of showers and thunderstorms exists during the middle part of this week. The primary hazards will be locally excessive rain and lightning. There is a low chance of few strong storms with gusty winds as well.

NEAR TERM

(Rest of tonight and Tuesday) Issued at 806 PM CDT Mon Aug 24 2026

A stationary front extended from just inland of the Carolina coastline through southern GA, AL and MS. Dew points have dipped into the middle 50s in southern middle %N to the middle to upper 60s in north AL. This will result in another pleasant overnight with lows in the lower 60s northeast to middle to upper 60s southwest with calm or light north-northeast flow.

SHORT TERM

(Tuesday night through Thursday) Issued at 806 PM CDT Mon Aug 24 2026

Tuesday through Thursday Another sunny and seasonably hot day is ahead with highs in the upper 80s to lower 90s expected. Dew points will be in the 60s, and perhaps mix down into the upper 50s in southern middle TN and the higher plateau locations. A northwest flow shortwave may bring some mid and high clouds during the day, but not expecting precipitation this far east given the dry low levels.

That changes late Tuesday Night into Wednesday as a shortwave or MCV induced wave drops southeast from KS through the Ozarks and into the mid South and TN Valley. Theta-E advection induced showers and thunderstorms (probably elevated/higher based) Tuesday night into Wednesday morning will affect mainly areas west of I-65. Then as the shortwave arrives, multiple clusters of showers and thunderstorms will develop across the region. This may result in areas receiving multiple rounds of heavy rain, so a low risk of excessive rainfall may develop. Temperatures may be impacted, so current NBM highs in the lower 90s may be somewhat suspect. We will monitor future model trends on this for possible adjustments. Low to medium chances of showers and thunderstorms will continue Wednesday Night into early Thursday as well as this shortwave drops deeper into the Southeast U.S. An actual surface frontal passage looks unlikely now until sometime late Thursday with additional chances of showers and thunderstorms along the front.

LONG TERM

(Thursday night through Monday) Issued at 806 PM CDT Mon Aug 24 2026

Thursday Night through Monday

The aforementioned frontal passage is forecast late Thursday night into early Friday, maintaining low to medium rain chances ahead of and along the front. As the upper level ridge and subsequent sfc high becomes centered over the southeast U.S., dry conditions return area- wide by Saturday and will likely be maintained through Monday. Highs during the long term period are forecast to warm into the low to mid 90s with heat indices reaching the upper 90s to around 100 degrees. No heat products are on the horizon for now, however, heat safety precautions are still encouraged to avoid heat illness. Be sure to stay hydrated and seek shade if outdoors.

AVIATION

(06Z TAFS) Issued at 140 AM CDT Tue Aug 25 2026

Although skies are clear at the moment at both HSV/MSL, weak atmoshperic lift (preceding a mid-level disturbance approaching the TN Valley from the northwest) will lead to an increasing coverage of Ac thru the early morning hours. A few lgt SHRA may also occur region-wide in the 10-16Z timeframe, but should come with little to no impact. As the disturbance progresses further south-southeastward and out of the region late this morning, skies will partially clear from N-to-S beginning early this aftn, with only a few lingering patches of Ac/Ci expected for the remainder of the period. Lgt ENE sfc flow will prevail early this morning, before becoming lgt/vrbl by the end of the TAF period.
