SPC AC 051703 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1203 PM CDT Sat Apr 05 2025 Valid 061200Z - 071200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS CENTERED OVER ALABAMA AND INTO PARTS OF ADJACENT STATES... ...SUMMARY... A wind-damage and isolated tornado threat is possible on Sunday across parts of the Southeast. Marginally severe wind gusts will also be possible in parts of the southern Appalachians. ...Synopsis... On Sunday, a positive-tilt trough will move slowly east out of the southern Plains and across the lower to mid MS Valley, with gradually increasing southwesterlies aloft across the Gulf Coast states. A weak surface low will move out of MS and across northern AL during the day, then northeastward across the western Carolinas overnight. A rain-reinforced front will extend south from the low, from northern AL into eastern MS and LA, with another boundary extending from TN into VA. A very moist air mass will exist across the warm sector, with moderate shear supporting scattered severe storms. ...Eastern MS and LA...AL... A line of thunderstorms will be ongoing along the cold front early on Sunday where MUCAPE will be on the order of 1000-1500 J/kg. Severe potential will be mitigated somewhat due to the relatively warm profiles aloft, however, veering winds with height and around 50 kt at 850 mb may support embedded supercells within the line, with both wind and brief tornado potential. Depending on the degree of outflow/convective contamination early in the day, a slightly better corridor of tornado threat could materialize. ..Jewell.. 04/05/2025 CLICK TO GET WUUS02 PTSDY2 PRODUCT NOTE: THE NEXT DAY 2 OUTLOOK IS SCHEDULED BY 0600Z
