Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1154 PM CST Tue Jan 11 2022
Valid 121200Z - 131200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms will be possible today in the vicinity of
Miami and southwestward in the area of the Florida Keys. No severe
threat is expected across the continental United States today or
tonight.
...DISCUSSION...
Northwest mid-level flow will remain over the Great Plains today as
an upper-level trough digs southeastward into the Mississippi
Valley. Ahead of the southern extension of the trough, a moist
airmass will be in place from the eastern Gulf of Mexico eastward
across the southern Florida Peninsula. Warming surface temperatures
late this morning into afternoon will create weak instability in the
vicinity of Miami, where isolated thunderstorm development will be
possible. The chance of thunderstorms could persist into this
evening as the upper-level trough approaches from the west.
Instability should remain too weak for a severe threat. Elsewhere
across the United States, thunderstorm development is not expected
today or tonight.
