601 ACUS48 KWNS 030824 SWOD48 SPC AC 030822 Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0322 AM CDT Thu Apr 03 2025 Valid 061200Z - 111200Z ...DISCUSSION... Models are in relatively good agreement for the Sunday/D4 to Monday/D5 period, depicting an elongating upper trough sweeping east from the OH/TN Valleys to the East Coast. On Sunday/D4, a leading midlevel wave is forecast to move out of AR and across TN/KY, with little amplitude and poor lapse rates by this time. An extensive area of rain and thunderstorms will be ongoing along the length of the cold front throughout the day, from the Northeast to the northern Gulf Coast. Some severe wind threat is expected, mainly over parts of the Southeast where dewpoints will be higher and as deep-layer shear remains favorable. The trend of widespread precipitation along this front will continue into early Monday/D5, from the Carolinas into FL. The severe risk should continue to dwindle as large-scale support weakens, but low-end potential cannot be ruled out over these areas. For the Tuesday/D6 to Thursday/D8 time frame, the weather pattern will be much less conducive to severe storms, with a ridge building over the West, and northwest flow across the central states. Periodic surges of high pressure are forecast, helping to keep conditions mostly stable over the bulk of the CONUS. ..Jewell.. 04/03/2025
