Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0220 AM CST Tue Feb 20 2024

Valid 221200Z - 231200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Organized severe thunderstorms are not currently forecast for
Thursday across the contiguous United States.

....Synopsis...
A belt of strong westerly mid-level flow will overspread the
Southeast, while an attendant disturbance over MO weakens as it
moves into the Upper OH Valley.  Concurrently, a large-scale trough
will amplify over the eastern half of the CONUS.  A surface low over
MO will weaken as it develops east into the OH Valley, while a cold
front pushes southeast from the Ozark Plateau through much of the
lower MS/TN Valleys.  Showers and isolated thunderstorms will likely
be ongoing within a warm-air advection regime over the Ozarks in
association with a LLJ centered over the lower MS Valley.  This
activity will likely spread east into a more weakly unstable
airmass, as moisture return north into the Mid South/OH Valley will
remain limited (lowest 100 mb mean mixing ratios 7-8 g/kg).
Considerable cloud cover will likely inhibit strong heating and
limit destabilization.  By late in the day into the overnight,
showers and possibly a few thunderstorms may develop along the
southeastward-surging front across TN southeastward into AL/GA.
