Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1234 AM CST Mon Jan 24 2022
Valid 251200Z - 261200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms are possible across portions of central and
southern Florida on Tuesday. Severe thunderstorms are not expected.
...Synopsis...
An expansive surface high is forecast to move from the northern
Plains southeastward into the Mid MS Valley. Continental air mass
associated with this area of high pressure will result in a dry and
stable conditions across the majority of the central and eastern
CONUS. The only exception is across FL, where low-level moisture
advection is anticipated Tuesday evening into Wednesday morning
ahead an approaching surface low. Dry conditions are anticipated
across the western CONUS as well, as a shortwave trough moves
southeastward across the Intermountain West and upper ridging begins
building along the West Coast in its wake.
...FL...
Parent shortwave trough for the approaching surface low will be
displaced to its north and east, limiting lift and keeping mid-level
temperatures warm across much of the FL Peninsula. Even so, some
elevated thunderstorms are still possible as this shortwave trough
moves across the northern FL Peninsula Tuesday afternoon. Additional
thunderstorms may develop Tuesday evening through Wednesday morning
across central and southern portions of the FL Peninsula.
Aforementioned warm mid-level temperatures will temper instability,
with the time of day also acting to reduce potential buoyancy,
particularly for any surface-based parcels. These factors suggest
thunderstorm coverage will be rather limited across the region, with
the severe thunderstorm threat also tempered by the meager buoyancy.
Greatest severe potential appears to be across southwest FL early
Wednesday morning, where the chance of surface-based buoyancy is
highest. Even so, current severe probabilities in that region are
too low to outlook.
