ZCZC SPCSWOMCD ALL ACUS11 KWNS 031806 SPC MCD 031806 FLZ000-032030- Mesoscale Discussion 0186 NWS Storm Prediction Center Norman OK 1206 PM CST Sun Mar 03 2024 Areas affected...central and southern Florida Concerning...Severe potential...Watch unlikely Valid 031806Z - 032030Z Probability of Watch Issuance...5 percent SUMMARY...Scattered strong thunderstorm development appears probable across much of the interior into southeastern peninsular Florida through 3-5 PM EST, accompanied by small to marginally severe hail and a risk for localized damaging wind gusts. DISCUSSION...Weak deep-layer warm advection appears underway across much of the Florida peninsula, with low-amplitude mid-level troughing in the process of gradually shifting offshore of the Atlantic coast. However, around 500 mb, temperatures are still generally around -13 to -15 C, with one lingering axis of colder temperatures forecast to spread across the interior peninsula into Atlantic coastal areas through 21-23Z. Beneath this environment, daytime heating of a relatively moist boundary layer with surface dew points ranging from the mid 60s to near 70 F is contributing to substantive destabilization, with CAPE increasing through 1000-1500+ J/kg. Although low-level convergence, and forcing for upward vertical motion in general, appears weak, deepening convection with widely scattered thunderstorm development is underway across the interior through southeastern peninsula coastal areas. And a gradual further increase and intensification of storms seems probable through mid to late afternoon, as potential instability peaks. Although flow in the lowest 5-6 km AGL is generally weak, stronger flow (50+ kt) in higher levels may still enhance thunderstorm development, and contribute to potential for small to marginally severe hail in the stronger cells developing this afternoon. As low-level lapse rates continue to steepen, heavy precipitation loading and latent cooling aided by melting hail probably will also contribute to potential for isolated locally damaging downbursts. ..Kerr/Hart.. 03/03/2024 ...Please see www.spc.noaa.gov for graphic product...
