SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1133 AM CDT Sat Oct 03 2020 Valid 041200Z - 051200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk for severe thunderstorms appears negligible across the U.S. Sunday through Sunday night. ...Synopsis... An upper trough from the Great Lakes to the lower MS Valley will develop east/northeast across the eastern U.S. on Sunday. At the surface, a cold front is forecast to extend from lower MI southwestward into central TX during the morning hours. The front will progress eastward across much of the eastern U.S. by Monday morning. A dearth of low level moisture will limit thunderstorm activity, though a lightning flash or two is possible across parts of the Ohio Valley where cold temperatures aloft will result in steep lapse rates amid shallow convection. However, coverage is expected to be sparse and less than 10%. Greater thunderstorm coverage is possible further southeast across the central/southern FL Peninsula where deeper boundary layer moisture and warmer temperatures will allow for greater destabilization ahead of the surface front. Additional isolated thunderstorms also are possible near the NC Outer Banks. Warm and dry conditions will continue across the western states as a strong upper level ridge persists. ..Leitman.. 10/03/2020
