660 ACUS01 KWNS 191620 SWODY1 SPC AC 191618 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1018 AM CST Sun Jan 19 2025 Valid 191630Z - 201200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER THE CENTRAL FLORIDA PENINSULA... ...SUMMARY... Strong thunderstorms may impact parts of central Florida this morning into this afternoon, and pose at least some risk for a tornado and locally damaging wind gusts. ...FL Peninsula... Expansive upper troughing covers the entirety of the CONUS this morning, with moderate southwesterly flow aloft throughout the base of this trough extending from the Southeast/Gulf of Mexico across the Mid-Atlantic States and FL. Surface analysis places a low over central NC. A cold front extends southwestward from this low through southeast GA and the FL Big Bend. Modest troughing precedes this front across central FL, with broad low-level confluence in the vicinity of this pre-frontal troughing contributing to showers and thunderstorms. Modest buoyancy persists over the region, with mesoanalysis estimating MLCAPE around 500 to 750 J/kg. Showers and thunderstorms are expected to continue throughout the day as the cold front and pre-frontal troughing both shift gradually southward. The environment will remain strongly sheared (i.e. effective bulk shear around 50-55 kt) throughout the afternoon, supporting the potential for a few more organized storms capable of damaging wind gusts and perhaps even a brief tornado or two. Wind fields will weaken with southern extent, with deep-layer vertical shear weakening as well. As such, the severe potential will likely maximize this morning into the early afternoon across the central FL Peninsula. ..Mosier/Jirak.. 01/19/2025 $$
