SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0629 PM CST Sun Jan 26 2025 Valid 270100Z - 271200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast across the contiguous United States through tonight. ...Synopsis... Isolated to scattered thunderstorms are expected to continue through the overnight hours along the southern CA coast and across parts of the south-central U.S. An upper wave evident in water-vapor imagery along the SoCal coast will gradually shift east/southeast towards the lower CO River Valley through 12 UTC Monday. Cold temperatures aloft within the upper trough axis, combined with broad-scale ascent, will continue to support adequate buoyancy for isolated, transient thunderstorms. Further east, weak ascent along a diffuse frontal zone and within the right-entrance of an upper-level jet will continue to promote isolated to scattered thunderstorms from the upper TX coast into the lower MS River Valley and parts of western AL. 00 UTC soundings from SHV and LCH sampled buoyancy that is sufficient for deep convection (MUCAPE between 100-200 J/kg), but likely inadequate to pose a robust severe threat. ..Moore.. 01/27/2025
