Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0625 AM CST Sat Nov 27 2021
Valid 271300Z - 281200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not expected across the contiguous United States
through early Sunday.
...Synopsis...
A midlevel low just west of the Big Bend will move eastward across
TX through tonight, while phasing gradually with a larger-scale
trough over the northeastern CONUS. Weak cyclogenesis is expected
along a coastal front just off the TX coast as the Big Bend midlevel
trough approaches from the west, though the modifying warm sector
and any associated thunderstorm threat will remain offshore.
Otherwise, the ridge west/trough east pattern will tend to maintain
a relatively dry, continental air mass across the majority of the
CONUS, precluding thunderstorms.
