KEY MESSAGES

Updated at 1009 AM CDT Fri May 8 2026

- Medium chances (40-70%) of showers and thunderstorms are expected Sunday afternoon into early Monday morning.

NEAR TERM

(Rest of Today and Tonight) Issued at 1009 AM CDT Fri May 8 2026

An overall nice Spring day is forecast today across the Tennessee Valley. High pressure centered over the Appalachians will bring light southeast flow, warming temperatures up into the low to mid 70s by this afternoon. As a shortwave ripples eastward along a stalled boundary near the Gulf Coast, cloud cover will begin to increase by this afternoon and evening from southwest to northeast. With the cloud cover overhead, not as cold tonight as lows only drop down into the low to mid 50s. A few CAMs indicate a very low chance of an isolated shower south of the Tennessee River late tonight, but most locations should remain dry through the night.

SHORT TERM

(Saturday through Sunday Night) Issued at 1009 AM CDT Fri May 8 2026

As we head into the weekend, a weak shortwave is forecast to push through the area on Saturday. Moisture is limited, especially north of the Tennessee River. Therefore, for areas south of the river a very low chance (5-15%) of isolated showers. Both warm air and moisture advection behind this shortwave begins to increase on Sunday ahead of an approaching cold front. With southerly sfc flow, temperatures are expected to warm up into the low to mid 80s on Sunday. This will increase SBCAPE between 500-1000 J/kg as the front passes through during the afternoon/evening hours. The good news is that severe storms are not expected, but medium chances (40-70%) for showers and storms will continue Sunday afternoon into the overnight hours.

LONG TERM

(Monday through Thursday) Issued at 1040 PM CDT Thu May 7 2026

Guidance is more convergent on a more amplified longwave trough axis and parent low moving from the Ohio Valley east through the area Sunday night into Monday. This could bring additional showers and thunderstorm activity to the area during that period, before much cooler air pushes back into the region.

AVIATION

(18Z TAFS) Issued at 1145 AM CDT Fri May 8 2026

VFR conditions with light southerly winds continue through tonight. A low cloud deck moves in from the southwest bringing a brief window of MVFR cigs to northern AL. Clouds scatter out late tomorrow morning into the afternoon hours with a return to VFR.
