Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0214 AM CST Mon Feb 28 2022
Valid 021200Z - 031200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not forecast across the Lower 48 on Wednesday.
...Synopsis...
An upper low will move east across Quebec, with broad area of
cyclonic flow across the Great Lakes and Northeast. An associated
midlevel jet will strengthen through the period to over 100 kt from
Lower MI to southern New England. Meanwhile, an upper ridge will
move very little over the Rockies, but an upper trough will approach
the West Coast late in the period.
High pressure will remain situated across the southeastern states as
well as over the northern Gulf of Mexico, and this will prevent
instability from developing with poor moisture trajectories.
Elsewhere, little to no CAPE is forecast across the Pacific
Northwest in advance of the next upper trough, thus thunderstorms
are unlikely anywhere across the CONUS on Wednesday.
