SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1219 AM CDT Tue Apr 08 2025 Valid 091200Z - 101200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are possible across portions of the the Middle Mississippi Valley and 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, while a related surface low and southwestward-extending cold front overspread the Mid MS/OH Valleys. Despite limited boundary-layer moisture, steep midlevel lapse rates will yield sufficient instability (albeit weak) for isolated thunderstorms along the front during the evening/overnight hours. While locally strong gusts cannot be ruled out, the weak instability should limit storm intensity. Farther west, ascent in the left-exit region of a southeastward-moving upper-level jet, combined with steep deep-layer lapse rates/marginal instability, will support isolated thunderstorms across the northern and central Plains. ..Weinman.. 04/08/2025
