SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0207 AM CDT Wed Oct 08 2025 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorm potential appears low on Friday. ...Synopsis... An upper ridge will persist over the Plains on Friday. Meanwhile, a shortwave upper trough will migrate east across the Great Lakes while a second upper trough moves inland across the Pacific Northwest. A weak surface front will develop southeast across the Upper Midwest as the upper trough ejects eastward. Some guidance suggests shallow, low-topped convection may develop near/just behind the front across the Great Lakes, though little lightning may accompany this activity. Moisture will increase northward across much of the western U.S. ahead of the upper trough and in relation to Hurricane Priscilla, which is forecast by NHC to approach the northern Baja peninsula on Friday. Isolated thunderstorms are expected, but weak instability will limit severe potential. Additional storms are possible across parts of FL as a surface cold front develops south across the Peninsula and into the Gulf. Poor lapse rates and weak instability/shear will preclude severe potential. ..Leitman.. 10/08/2025
