Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1149 PM CST Tue Jan 25 2022
Valid 261200Z - 271200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms are possible across portions of southern
Florida Wednesday. Severe weather is not forecast.
...Southern Florida...
Deamplifying short-wave trough is moving across GA/northern FL late
this evening. As a result, mid-level flow will become decidedly
westerly with a few weak disturbances expected to translate across
low latitudes toward the FL Peninsula. Air mass over FL is
seasonally cool with stable boundary-layer conditions as higher
quality moisture currently resides across the Keys/FL Straits. Deep
convection, with lightning, continues along the front over the
southeast Gulf Basin where buoyancy is considerably greater, and
this activity will likely struggle to move inland until moisture
advances north across south FL. Even so, forecast soundings exhibit
pseudo-adiabatic lapse rates in the lowest 5-6km; although, adequate
deep-layer shear could sustain convection. While SBCAPE will
increase as moisture returns, poor lapse rates and weak low-level
flow suggest the primary risk with this convection will be locally
heavy rainfall, and severe thunderstorms are not expected.
