Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1228 AM CST Thu Nov 25 2021
Valid 261200Z - 271200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
No thunderstorms are forecast to develop across the contiguous
United States on Friday.
...Synopsis...
Upper troughing is forecast to cover the eastern CONUS early Friday
morning, while an upper low remains centered over the Baja Peninsula
and a belt a strong westerlies stretches from the northeast Pacific
Ocean into the northern High Plains. The eastern CONUS upper trough
is expected to remain progressive, quickly moving off the Eastern
Seaboard while becoming more negatively tilted with time. A
shortwave trough will move quickly through the westerlies, moving
across the Pacific Northwest and northern Rockies and reaching the
northern/central High Plains by early Saturday morning. At the same
time, the upper low over Baja is expected to slowly drift eastward
into northwest Mexico.
At the surface, a cold front will likely stretch from southern New
England southwestward through the eastern Carolinas and off the
coast of the central FL Peninsula early Friday. This front will move
eastward/southeastward throughout the day, but limited low-level
moisture and buoyancy preceding the front will preclude thunderstorm
development. A dry continental air mass is anticipated across the
remainder of central and eastern CONUS in the wake of this front,
with stable conditions precluding thunderstorm development.
