SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1027 AM CST Sun Dec 19 2021
Valid 191630Z - 201200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected through tonight.
...Northern Florida/southeast Georgia...
A moist and modestly unstable air mass precedes an
east/southeastward-advancing cold front. Widely scattered showers
and thunderstorms will remain a possibility, with the potential for
thunderstorms to redevelop along the front this afternoon in the
wake of more prevalent activity in the predawn hours. While a strong
wind gust or two could occur, the potential for severe-caliber
storms is likely to remain minimal given weak lapse rates aloft and
the marginality of overall buoyancy.
...South Texas...
As per the 12Z observed sounding from Brownsville, thermodynamic
profiles ahead of an approaching upper trough over northern Mexico
will be marginally supportive of isolated elevated thunderstorms
today into tonight, particularly in closer proximity to the Rio
Grande.
