430 ACUS48 KWNS 240751 SWOD48 SPC AC 240750 Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0250 AM CDT Tue Sep 24 2024 Valid 271200Z - 021200Z ...DISCUSSION... A low-end tropical cyclone related tornado risk may continue into Day 4/Fri from parts of the Southeast toward the central Appalachian vicinity. However, spread among medium range guidance is quite large at this time frame regarding the position of the remnant tropical cyclone. Beyond Day 4/Fri, medium range guidance generally maintains an closed upper cyclone across the broader Mid-South and Ohio Valley vicinity through Day 6/Sun before this feature weakens and an open wave trough evolves and progresses east toward the Atlantic coast through early next week. Meanwhile, upper ridging will persist across much of the western half of the CONUS. Overall, severe potential beyond Day 4/Fri appears low given areas of widespread precipitation and cloudiness, along with limited instability and weakening deep-layer flow with time. ..Leitman.. 09/24/2024
