KEY MESSAGES

Updated at 832 PM CDT Sun Sep 6 2026

- Afternoon highs in the upper 80s to lower 90s with heat index values in the mid to upper 90s continue through the work week.

- Medium chances for showers and storms return on Thursday.

NEAR TERM

(Rest of tonight and Monday) Issued at 833 PM CDT Sun Sep 6 2026

A backdoor cold front is slowly progressing through the local forecast area this evening bringing in a drier and a little bit cooler airmass. The front did initiate several showers earlier this evening and for the most part they have all dissipated. Behind the front, upper 60s to lower 70s dewpoints are advecting into the region making for a more comfortable evening. Expect tranquil conditions to persist through the night with morning lows in the upper 60s to lower 70s.

With the arrival of the aformentioned cold front, the large amplitude upper level ridge that brought the dangerous heat this past week has been pushed back to the west. While it will still be hot during the day on Monday with afternoon highs in the upper 80s to lower 90s, heat indices will only be the upper 90s to around 100 degrees. Outside of the heat, the only other weather concern is a very low chance (5-15%) of an isolated afternoon shower or storm in NE AL.

SHORT TERM

(Monday night through Wednesday Night) Issued at 833 PM CDT Sun Sep 6 2026

As we head through the first half of the work week, the large amplitude ridge over the central CONUS flattens out bringing a more zonal flow pattern to much of the southern US. This results in afternoon highs in the lower 90s with overnight lows in the upper 60s to lower 70s. Dry conditions should persist as well as we remain under the influence of sfc high pressure centered over the Mid-Atlantic. Despite temperatures being a few degrees cooler this week, it will still feel quite warm and NWS Heat Risk is forecast to be Moderate (level 2 of 4). Be sure to continue practicing heat safety to avoid heat illness if spending time outdoors.

LONG TERM

(Thursday through Sunday) Issued at 833 PM CDT Sun Sep 6 2026

The main feature of discussion during the long term period will be a closed low system shifting eastward just north of the Great Lakes region, bringing a cold front southeastward into the Tennessee Valley by Thursday night. Ahead of and along the frontal boundary, increased chances (30-50%) of showers and thunderstorms are forecast Thursday afternoon into Friday. While there will likely be a lull in storm activity sometime Friday, this will be short-lived as an upper level shortwave shifts eastward into the area ahead of an upper level ridge that is forecast to set up over the southern Plains. Low to medium chances (20-40%) of showers and thunderstorms are forecast to continue through the weekend. Outside of the mentioned rain chances, heat will continue to be a concern. Highs are forecast to remain in the upper 80s to mid 90s with heat indices near 100 degrees. While this is below local Heat Advisory criteria, we encourage everyone to remain hydrated and practice heat safety while outdoors.

AVIATION

(00Z TAFS) Issued at 549 PM CDT Sun Sep 6 2026

VFR conditions with light northerly winds will continue through the TAF period. While there is a very low chance of an isolated shower or thunderstorm near the terminals this evening, confidence was too low to include at this time.
