Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
0100 AM CST Sun Feb 13 2022
Valid 141200Z - 151200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not expected on Monday.
...Synopsis...
The upper pattern early Monday is forecast to feature predominantly
northwesterly flow across the majority of the CONUS. An embedded
shortwave trough, accompanied by a belt of strong mid-level flow, is
expected to move from its early day position over the Upper Great
Lakes east-southeastward off the northern Mid-Atlantic coast.
Farther west, a strong shortwave trough is expected to drop south
through the Pacific Northwest into central CA and the western Great
Basin. The strong flow aloft associated with this shortwave will be
confined to its western periphery, stretching from western/central
OR through central CA by early Tuesday morning. Strong forcing for
ascent will accompany this shortwave, and a few deeper updrafts are
possible amid the buoyancy resulting from cold mid-level
temperatures. Overall thunderstorm coverage in this area is expected
to be less than 10 percent.
Recent intrusion of dry, continental air will result in stable
conditions across the CONUS on Monday. Southerly flow will
strengthen across the western Gulf of Mexico late Monday evening
through Tuesday morning, but the more substantial low-level moisture
will remain offshore. Consequently, despite a fairly active pattern
with several shortwave troughs, thunderstorms are not anticipated
across the majority of the CONUS.
