KEY MESSAGES

Updated at 1040 PM CDT Thu May 7 2026

- Expect fog to develop overnight. Some patchy dense fog could occur in shelter valley locations of NE Alabama.

- Low to medium chances for showers and a few thunderstorms return this weekend.

NEAR TERM

(Today) Issued at 237 AM CDT Fri May 8 2026

2 AM satellite shows high clouds slowly trespassing through the area. Despite this, temps are still cooling slightly with current temperatures in the high 40s to low 50s. The weak radiational cooling paired with calm winds has allowed some areas of patchy to locally dense fog. Current thinking is the cloud cover will inhibit widespread dense fog, dissuading the need for an advisory, yet the low dew point depressions will support patchy to locally dense fog through the early morning hours.

Come sunrise, any fog present will burn of. Surface high pressure will dominate the area through the day even as it pushes east towards the Atlantic coast. High pressure influence will keep showers and storms associated with a Gulf coast stationary front well to our south even as flow returns to the south.The southerly flow will mildly increase our dew points and temperatures with highs in the mid 70s this afternoon. While dry weather will prevail, high clouds associated with the stationary front to our south will increase in coverage through the afternoon. These clouds will be the prelude to a slightly more unsettled pattern in the short term.

SHORT TERM

(Friday night through Sunday) Issued at 1040 PM CDT Thu May 7 2026

Towards midnight Friday night, a longwave trough axis moves quickly east into the Ohio Valley region. Advection ahead of this feature could help to enhance low level moisture advection enough to aid isentropic lift near and north of the stalled front over Louisiana and southern Alabama. This could produce some isolated to scattered shower activity over the area after midnight on Friday night into the morning hours on Saturday.

Model guidance really diverges on how far north the surface front to our south moves though Saturday afternoon into Saturday evening. For now kept the forecast on the drier side with the slower movement of the front northward. That being said can't rule out isolated to scattered showers or thunderstorms by Saturday afternoon especially. Shear is very minimal, but may approach 30-35 knots (but models are not in sync on that). If that happens a few strong storms may be in the cards Saturday afternoon evening.

We may see the front push southeast Saturday night through the area, but again models are not in total agreement. If it does, dry weather and a nice day will be in store on Sunday. A few models do hint at some rain and thunderstorms pushing northeast though ahead of another approaching trough axis. Either way, with WSW flow in place we should warm up into the upper 70s to lower 80s again over the weekend.

LONG TERM

(Sunday night 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

(12Z TAFS) Issued at 545 AM CDT Fri May 8 2026

VFR conditions will prevail through the day and much of the night. After 6Z, low MVFR ceilings will move in from the south. Subsequent TAF updates will refine timing and height of low ceilings.
