Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0656 AM CST Wed Jan 26 2022
Valid 261300Z - 271200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms are possible across portions of southern
Florida today through early evening, although severe storms are not
expected.
...South Florida...
A weakening southern-stream shortwave trough continues to steadily
progress offshore toward the Atlantic, with neutral/slightly rising
heights today in its wake. Additional low-level moistening will
continue to occur today into the southern Florida Peninsula
near/south of a west/east-oriented front, and ahead of a weak
surface wave that will transition from the eastern Gulf of Mexico
toward off the southeast Peninsula by tonight.
Mid-level subsidence may have a detrimental effect, but weak
convergence near the front, perhaps aided by an east-coast sea
breeze, will influence shower/thunderstorm development into this
afternoon within an increasingly moist and modestly unstable air
mass. A couple of stronger/sustained storms could materialize in the
presence of 800-1000 J/kg MLCAPE and moderately long/semi-straight
hodographs. However, the influences of weak convergence, weakening
low-level winds, a lingering subsidence inversion aloft, and
pseudo-adiabatic lapse rates are expected to temper
updraft/downdraft intensity, likely keeping the potential for severe
storms low.
