SPC AC 200714 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0214 AM CDT Fri Apr 20 2018 Valid 221200Z - 231200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM SOUTHERN AL/SOUTHEAST LA EASTWARD THROUGH THE FL PANHANDLE... ...SUMMARY... Isolated severe thunderstorms are possible across portions of the Southeast states and Florida Panhandle. ...Synopsis... An upper low will continue eastward through the Lower MS Valley and into the Southeast states on Sunday. A weak surface low will move eastward/southeastward just ahead of this upper low, likely tracking generally southeastward along a warm front. By 12Z Monday, this surface low is expected to be centered over southeast AL, with a cold front extending southward into the Gulf of Mexico and a warm front extending southeastward into the FL Big Bend. ...Eastern LA into FL Panhandle/Big Bend... Modest destabilization is anticipated within the warm sector ahead of the surface low. More robust destabilization will be tempered by widespread cloudiness but continued moisture advection will likely result in dewpoints in the low to mid 60s and MLCAPE around 500 J/kg. The position of the warm front has varied within the guidance over the last few runs and the current expectation is for the front to extend from near MEI southeastward to near AAF at 21Z Sunday. Despite modest instability, strong shear supports the potential for a few organized storms along and south of the warm front during the afternoon. A more developed convective line is possible over the north-central Gulf as the cold front moves through the area. This line could impact the FL Big Bend very late in the period. Marginal severe probability (i.e. 5%) has been introduced across these areas. Uncertainty and generally modest severe potential preclude higher probabilities with this outlook. ..Mosier.. 04/20/2018 CLICK TO GET WUUS03 PTSDY3 PRODUCT NOTE: THE NEXT DAY 3 OUTLOOK IS SCHEDULED BY 0730Z
