KEY MESSAGES

Updated at 843 AM CDT Sat May 23 2026

- A wet weather pattern will continue for the next seven days.

- Low risk of excessive rain and flash flooding during this period.

- Gusty winds and lightning will be the other hazards associated with thunderstorms.

NEAR TERM

(Rest of Today and Tonight) Issued at 843 AM CDT Sun May 24 2026

An MCV was lifting northeast into southwest AL this morning. northwest of the center, a persistent band of deep layer convergence was generating showers and embedded thunderstorms from southeast MS into north AL. The lightning activity has been limited thus far, but with daytime heating, this will tend to pick up. Locally heavy rainfall will occur in this persistent band as it lifts northeast into the north and northeast AL. There may be a break in the activity this afternoon as this band shifts further east this afternoon as the MCV departs. Then, added heating should generate additional isolated to scattered showers and thunderstorms. CAMS show a relative minimal after daytime heating ceases this evening, so PoPs become lower overnight. Afternoon highs will be in the upper 70s to lower 80s followed by lows in the 60s tonight.

SHORT TERM

(Monday through Tuesday) Issued at 843 AM CDT Sun May 24 2026

Deep layer southerly flow will persist through the southeast and TN Valley on Monday into Tuesday between a weak 5h low over the ARKLATEX region and a Bermuda high. The western low lifts north- northwest as a trough digs into the Rockies. Southerly flow increases to 20-25kt in the 8-5h layer with general confluent flow persisting in a high PW/theta-E airmass. Thus, a continued risk of locally excessive rainfall is expected. High temperatures will be similar both days in the upper 70s to lower 80s with lows in the 60s.

LONG TERM

(Tuesday night through Saturday) Issued at 1059 PM CDT Sat May 23 2026

Unsettled weather will continue for the remainder of next week, with daily chances of showers and thunderstorms. The circulation rounding surface high pressure off of the east coast will continue bringing deep moisture from the Gulf region well inland. Rain chances however will begin to take on a more diurnal trend as we go into the latter portion of the week, with the highest chances in the afternoon and early evening. Daily high temperatures should range in the low/mid 80s and lows in the mid 60s. A frontal boundary is forecast to move across the area on Saturday from the north. Depending upon far south it moves, rain chances next week may indeed become lower.

AVIATION

(18Z TAFS) Issued at 1134 AM CDT Sun May 24 2026

Bands of +SHRA with embedded +TSRA will continue along and east of the I-65 corridor through this afternoon. This will primarily affect areas along and east of KHSV with a lower chance at KMSL of additional SHRA or TSRA. Ceilings will remain at or below 030agl at KHSV (MVFR and spotty IFR) through the rest of the period. At KMSL, VFR conditions are expected through 04Z before lower clouds redevelop and lower from MVFR to IFR. SHRA activity tonight will be more isolated to scattered in coverage. By 11Z, most areas will have ceilings below 010agl IFR.
