SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1200 PM CDT Sat Apr 12 2025 Valid 131200Z - 141200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Sunday. ...Synopsis... A deep upper trough will depart the East Coast Saturday night, with a surface high settling over the Southeast on Sunday. To the west, a shortwave trough will move east out of MT and toward the upper MS Valley by Monday morning. A cold front in association with this trough will quickly push across the northern and central Plains, with a pre-frontal trough roughly from MN into MO and southwestward into OK. Given the southeastern surface high, moisture return will be limited ahead of the Plains feature. However, cooling aloft and steepening of lapse rates, as well as lift will allow for elevated instability to develop into the upper MS Valley and Great Lakes, supporting isolated to scattered thunderstorms overnight. Weak instability should preclude any severe threat. ..Jewell.. 04/12/2025
