KEY MESSAGES

Updated at 816 PM CDT Fri Sep 11 2026

- Low to medium chances of rain will remain in the forecast through Saturday night with little to no risk for severe weather.

- NWS Heat Risk will remain in the Minor to Moderate category throughout the forecast period.

NEAR TERM

(Rest of tonight and Saturday) Issued at 816 PM CDT Fri Sep 11 2026

Storm coverage and intensity has waned significantly over the last two hours. Currently the only notable feature is a band of weakening storms draped over TN and MS. Models suggest this band will both weaken and erode to the north by midnight, keeping us mostly dry overnight. Cloud cover will remain overnight and only allow temperatures to drop a few degrees from current conditions with lows in the high 60s to low 70s.

Through the day tomorrow a passing shortwave will provide support for another round of afternoon showers and thunderstorms. Under SSW flow at the surface and aloft, we remain incredibility moist with high dew points and PWATS for mid September. The moist conditions will aid the weak forcing and allow showers and a few thunderstorms to develop across the area by midday. Cloud cover in the morning will limit our instability. Without any significant shear either, strong to severe storms are not forecast. Rather, heavy rainfall will again be the main threat. Rain looks to decrease in coverage and push SE come sunset with dry conditions building in overnight

SHORT TERM

(Saturday night through Monday night) Issued at 816 PM CDT Fri Sep 11 2026

Through the short term, ridging in the mid levels will build over the TN Valley. Despite the recent rain, our hot and humid conditions will return. Highs will rebound back to the 90s on Sunday and Monday. With dew points still in the mid 70s, heat indices will quickly surge above triple digits. While the current forecast keeps us below heat advisory criteria, this heat will still be dangerous for those partaking in outdoor activities. Make sure to continue to practice proper heat and sun safety!

LONG TERM

(Tuesday through Friday) Issued at 816 PM CDT Fri Sep 11 2026

The main impact of the long term period will be the hot and humid conditions. The upper level ridge remains entrenched over most of the eastern US. As a result, afternoon highs are forecast to climb into the low to mid 90s, which is 5 to 10 degrees above normal for this time of year. Dewpoints should remain in the upper 60s to lower 70s keeping max heat index values between 97-104 degrees. While this is just below advisory criteria, it will still be dangerously hot. For those with outdoor plans next week make sure to practice good heat safety and if possible limit outdoor exposure during the afternoon hours. The one change in the long term period forecast is that high pressure is more centered over Alabama which would limit any afternoon convection. Hence, PoPs have decreased Tuesday and Wednesday resulting in a dry forecast. There is still a low chance of afternoon showers and storms both Thursday and Friday, but given no significant forcing mechanism in place, coverage should be quite low.

AVIATION

(00Z TAFS) Issued at 545 PM CDT Fri Sep 11 2026

Light SHRA will continue for a few hours after 00Z with a low chance for thunder. Showers look to clear by 06Z, with a low MVFR cloud deck building in for the overnight hours. Widespread MVFR conditions look likely through sunrise with the potential for periods of IFR, amendments will be made to the TAF as necessary. Ceilings will slowly lift after sunrise, yet likely remain below VFR. Scattered showers will return Saturday afternoon with best chances between 18Z and 00Z. Future TAF issuances will refine timing and intensity of showers.
