118 ACUS03 KWNS 281850 SWODY3 SPC AC 281849 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0149 PM CDT Thu Aug 28 2025 Valid 301200Z - 311200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few strong storms are possible across the southern High Plains on Saturday. ...Central/Southern High Plains... An upper level northwest flow regime will persist on Saturday, with a large-scale upper trough remaining over the eastern U.S. while ridging builds over the West. South/southeasterly low-level flow will maintain 60s F dewpoints across eastern CO/western KS southward into eastern NM and western TX. Steep midlevel lapse rates will foster MLCAPE in the 1000-2000 J/kg range across the High Plains. Thunderstorms are expected to develop over the higher terrain by mid-afternoon and spread east/southeast into better boundary layer moisture and more favorable instability. Vertical shear will remain modest, but vertically veering profiles will support 20-30 kt effective shear. Elongated forecast hodographs suggest small hail will be possible within this environment, while steep low-level lapse rates support stronger downdrafts and locally gusty winds. Severe probabilities could be need for parts of the region in subsequent outlooks if confidence increases in a more concentrated corridor of marginal severe potential. ..Leitman.. 08/28/2025 $$
