SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0221 PM CDT Fri Apr 11 2025 Valid 131200Z - 141200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Sunday or Sunday night. ...Upper MS Valley/Great Lakes... A mid-level shortwave trough across the northern Plains will amplify as it moves into the Upper Midwest on Sunday. At the surface, an area of low pressure will move generally from the central Plains into the northern Great Lakes. A cold front will extend from this surface low south and then southwest to the central Plains. Ahead of this front, upper 50s to perhaps low 60s dewpoints are forecast which should be result in weak surface based instability Sunday afternoon. Guidance varies on the position of the surface low and destabilization ahead of the front. Long/straight hodographs within the cloud bearing layer should support some storm organization and the potential for some strong to locally severe storms. However, strong capping is forecast ahead of the front with thunderstorm potential mostly confined near the surface low. Destabilization should also be more limited farther north. Therefore, a narrow corridor of an uncapped warm sector with sufficient destabilization and shear for an isolated severe weather threat may exist, but is unclear if/where this may occur at this time. ...CO/KS... A few thunderstorms are possible along and north of a cold front across eastern Colorado and into western Kansas as a shortwave trough transits the central Rockies. Moisture/instability is expected to be limited which should keep any thunderstorm potential isolated. ..Bentley.. 04/11/2025
