KEY MESSAGES

Updated at 953 PM CST Sun Nov 8 2026

- A Frost Advisory has been issued for all counties in northern Alabama from 11 PM tonight through 7 AM CST on Monday. Low temperatures will fall into the low to upper 30s tonight.

- A low chance of patchy frost is also forecast Monday night into early Tuesday morning.

NEAR TERM

(Today) Issued at 354 AM CST Mon Nov 9 2026

Surface high pressure (centered across the Arklatex region) will gradually expand southwestward into the Rio Grande Valley and northeastward into the central Appalachians over the course of the near term period, resulting in a continuation of light/variable- calm flow across the local area. Environmental conditions have once again been quite favorable for radiational cooling early this morning, with a fairly widespread coverage of fog (some locally dense) in river valleys and near large lakes. Although most of the CWFA will experience low temperatures in the 33-37F range, localized areas may briefly fall into the 30-32F range (resulting in freezing fog). Otherwise, a patchy-areal coverage of frost is still anticipated region-wide by sunrise, and a Frost Advisory remains in effect for all zones in northern AL until 8 AM CST. Regarding the rest of the day, aside from a few passing high clouds in light westerly flow aloft, abundant sunshine is expected, and this will promote afternoon highs in the u60s-l70s.

SHORT TERM

(Monday night through Wednesday) Issued at 953 PM CST Sun Nov 8 2026

Models continue to show upper level ridging feeding into the Tennessee Valley through mid week, with highs reaching the upper 60s to lower 70s and overnight lows dropping into the 30s to 40s. This pattern will change by mid week as an upper level low shifts eastward toward the area from the Deep South into the mid Mississippi Valley. As this continues into the Ohio River Valley, an associated cold front is forecast to push southward into northern AL and southern middle TN on Wednesday. Rain chances will be heavily dependent on the official track of the low, however, current guidance supports at least a low to medium chance of showers and thunderstorms Wednesday evening into Wednesday night (with higher chances remaining north of the TN River). The main talking point with this front will be the cold temperatures to follow. More on this in the long term below.

LONG TERM

(Wednesday night through Sunday) Issued at 953 PM CST Sun Nov 8 2026

By Thursday morning, a strong cold front will have passed southeast through the TN Valley, with blustery north winds developing. Lingering showers in the strong cold advection aloft will persist in our northeast counties. Elsewhere, a stratus or stratocu deck will persist, limiting much solar heating to counter the cold advection. So temperatures will likely remain steady in the 50s much of the day. Wind gusts of 25-30 mph are likely through much of the day. Overnight lows will then dip into the lower to middle 30s.

A large gyre will remain in place over the Great Lakes region through Friday, then shift east over the weekend. This will maintain a steady and deep layer northerly flow across much of the eastern CONUS. A widespread freeze has a high probability of occurrence Friday and Saturday nights with lows in the middle to upper 20s for most areas. Highs will only be in the lower 50s Saturday in valley areas and middle to upper 40s atop the Cumberland Plateau. Highs recover into the upper 50s to lower 60s on Sunday.

AVIATION

(06Z TAFS) Issued at 1212 AM CST Mon Nov 9 2026

Clear skies are expected from early this morning through late this aftn, although a few patches of thin Ci may periodically spread across the region in light WNW flow aloft. As mid-level flow backs to WSW and begins to strengthen this evening, a notable increase in the coverage/density of Cs is anticipated by the end of the period. Sfc winds will remain lgt/vrbl-calm, and although patchy (but perhaps locally dense) FG or FZFG may develop in a few locations early this morning, we will not include vsby reductions in either TAF attm.
