Mesoscale Discussion 0838 NWS Storm Prediction Center Norman OK 0453 PM CDT Sun May 19 2024 Areas affected...Southeast Florida Concerning...Severe Thunderstorm Watch 258... Valid 192153Z - 200000Z The severe weather threat for Severe Thunderstorm Watch 258 continues. SUMMARY...The threat for large hail and damaging winds continues across parts of the southeast Florida coast. DISCUSSION...Regional radar imagery and surface observations continue to show deep convection developing along and behind a southward-surging outflow boundary along the southeast FL coast. While most storms have struggled to intensify due to the undercutting nature of the boundary, a few deeper cells have managed to mature within an otherwise favorable supercell environment. A sea-breeze boundary remains evident along the southeastern FL coast ahead of the outflow boundary, and while deeper convective initiation has occurred within the past hour, strengthening low-level westerly winds has shifted the boundary closer to the coast, resulting in quick storm propagation offshore. The general expectation over the next 1-2 hours is for a continuation of scattered thunderstorms along the southeast FL coast with a few strong to severe cells capable of large hail and damaging winds. This threat will gradually abate through the evening hours amid the onset of nocturnal cooling and a continued southward surge of the undercutting outflow boundary. ..Moore.. 05/19/2024 ...Please see www.spc.noaa.gov for graphic product...
