0655 PM CST Tue Nov 25 2025
Valid 260100Z - 261200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
SOUTHERN ALABAMA AND INTO THE FLORIDA PANHANDLE AND SOUTHWEST
GEORGIA...AND OVER DEEP SOUTH TEXAS...
...SUMMARY...
Isolated strong storms remain possible from southern Alabama into
western Georgia and the Florida Panhandle through late evening, and
over Deep South Texas.
...AL into southwest GA and the FL Panhandle...
A marginally unstable air mass remains ahead of a cold front this
evening, extending from northwest GA across central AL. Scattered
thunderstorms are ongoing near/ahead of the front, with minimal
indications of severe potential currently. However, PWAT values up
to 1.50" persist, with minimal convective inhibition especially over
southern areas. Southwest 850 mb winds near 30 kt is also supporting
areas of 100-150 m2/s2 effective SRH, which could aid rotation in
the stronger storms. As such, will maintain the Marginal Risk, with
a low-end risk of a brief tornado or locally damaging gusts over the
next several hours.
...Deep South TX...
Weak easterly low-level flow persists this evening south of a
developing cold front, with 70s F dewpoints onshore. The 00Z CRP
sounding show minimal capping, though winds are weak below 700 mb.
Farther south, the 00Z BRO soundings still indicates substantial
capping. Latest radar already indicates convective showers may be
developing inland.
Conditionally, the environment supports hail over 1.00" diameter,
with MLCAPE over 1500 J/kg and deep-layer effective shear around 50
kt. The primary uncertainty is due to weak lift. However, the cold
front will eventually push south into the moist and unstable air
mass later tonight, and this may result in sufficient lift for a few
strong to perhaps severe thunderstorms with localized hail threat.
As such, 5% hail probabilities have been added.
