2AM Day 3 Convective Outlook for Sunday, August 31. NO SEVERE THUNDERSTORM AREAS FORECAST
SUMMARY
A couple of strong storms cannot be ruled out in the central Plains on Sunday.
Synopsis
A mid-level trough will eject into the Atlantic while another mid-level trough retrogrades northwestward from the Pacific Northwest, resulting in a broad northwesterly flow regime across most of the CONUS on Sunday. Surface lee troughing will persist across the Plains states, where adequate moisture will be in place to support isolated to scattered thunderstorms. Guidance consensus shows that both vertical wind shear and instability will be rather weak over the Plains. While isolated instances of sub-severe wind and hail are possible, the threat for severe hazards appears too sparse to warrant severe probabilities this outlook.
