Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0149 AM CDT Fri Oct 03 2025 Valid 051200Z - 061200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorm are not forecast for Sunday. ...Central Plains... An upper shortwave trough over the northern Plains Sunday morning will develop northeast into Ontario through the afternoon. Meanwhile a larger-scale positive-tilt upper trough will persist across the western U.S. as a second upper shortwave trough develops southeast across the Canadian Prairies into the northern Plains toward the end of the period. At the surface, a cold front will develop east/southeast across the Upper Midwest into the central Plains. Modest boundary layer moisture will be in place ahead of the front (mid 50s to low 60s F dewpoints). Destabilization is expected remain modest, generally below 1000 J/kg near the surface front, in particular from western KS into the eastern NE vicinity. Isolated to scattered showers and thunderstorms will be possible during the late afternoon/evening. Warm midlevel temperatures will likely preclude stronger convection by limiting instability, though a strong storm or two could produce gusty winds. ..Leitman.. 10/03/2025
