Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1139 PM CST Tue Jan 11 2022
Valid 131200Z - 141200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated weak thunderstorms may occur during the early morning hours
Thursday over parts of the Florida Peninsula.
...Synopsis and Discussion...
A 100 kt midlevel speed max will dive southeastward across the mid
MS Valley during the day, nosing into the Southeast by 00Z. By 12Z
Friday, the associated upper trough will be near the coastal
Carolinas, with strong northwest flow situated over GA and FL.
Meanwhile, an upper ridge over the Rockies will flatten as a
shortwave trough moves from the Pacific Northwest into the Great
Basin.
At the surface, northerly winds will exist over the Gulf of Mexico,
and will increase over FL through the period. Dewpoints over FL will
largely be in the 50s F during the day, which may support minimal
instability. Showers and isolated thunderstorms will be possible
across the FL Peninsula early in the day prior to rapid drying from
the west during the afternoon. Weak instability as well as weak
winds below 700 mb suggest non-severe thunderstorms are most likely.
