ACUS11 KWNS 291254 SWOMCD SPC MCD 291254 FLZ000-291500- Mesoscale Discussion 2317 NWS Storm Prediction Center Norman OK 0654 AM CST Sun Dec 29 2024 Areas affected...the FL Keys and extreme south Peninsula Concerning...Severe potential...Watch unlikely Valid 291254Z - 291500Z Probability of Watch Issuance...5 percent SUMMARY...A waterspout moving onshore as a tornado is possible across parts of the Keys into the far south Florida Peninsula through midday. DISCUSSION...An MCV has been drifting east in the offshore waters, west of the southern Everglades and north of the Lower Keys, this morning. The airmass to its south, across the Keys, has maintained mid to upper 70s surface temperatures coupled with low 70s dew points. The 12Z KEY sounding sampled this air mass well, which is characterized by poor mid-level lapse rates but MLCAPE near 1000 J/kg. While low-level shear within the sounding and BYX VWP data has been modest and is expected to remain so, veering of the wind profile with height is yielding a favorable environment for occasional supercell structures within a regenerative storm cluster. As this activity likely drifts closer to land through midday, a brief tornado is possible. ..Grams/Edwards.. 12/29/2024 ATTN...WFO...MFL...KEY...
