SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1212 PM CDT Tue Apr 08 2025 Valid 091200Z - 101200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are possible across portions of the Midwest, the Upper Midwest, and the northern High Plains, though severe storms are not expected. ...Synopsis and Discussion... A midlevel trough will amplify as it advances southeastward from the northern Plains into the Midwest on Wednesday, while a surface low will develop over Missouri and moves into the Lower Ohio Valley. A cold front will extend southwestward from this surface low with a warm front to the northeast. Despite limited boundary-layer moisture, steep midlevel lapse rates will yield sufficient instability (albeit weak) for isolated thunderstorms along the warm front during the evening/overnight hours. Some thunderstorms may develop along the cold front where slightly greater instability is forecast. Locally strong gusts cannot be ruled out, but the weak instability should limit storm intensity. Isolated thunderstorms are expected across the northern Plains and Upper Midwest as a mid-level trough amplifies and moves south and a mid-level jet streak overspreads the region. ..Bentley.. 04/08/2025
