SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0214 PM CDT Mon Oct 27 2025 Valid 291200Z - 301200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Little to no thunderstorms are expected on Wednesday. ...Synopsis... An upper low will deepen on Wednesday as it swings northeastward out of AR and toward the upper OH Valley late. This low will be within a large upper trough which will amplify across much of the Southeast and toward the Mid Atlantic into Thursday. Cool northerly surface winds will exist over much of the central US, with a somewhat broad area of low pressure over the Southeast ahead of the upper trough. A cold front will be moving across the northern Gulf early Wednesday, with a minimal moisture plume perhaps extending northeastward toward the FL Panhandle. There may be scattered showers along this front, but relatively poor lapse rate profiles suggest any convection would be weak and perhaps shallow. Otherwise, the air mass ahead of the upper trough should remain mostly stable, the exception being the possibility of highly elevated instability wrapping northwestward across the Mid Atlantic. While a lightning flash cannot be ruled out late Wednesday into Wednesday night in that region, the overall threat of thunderstorms or any substantial lightning appears minimal. ..Jewell.. 10/27/2025
