SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1007 AM CST Sun Nov 28 2021 Valid 281630Z - 291200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible in the late afternoon and early evening near Lake Erie. ...Lake Erie... A shortwave trough will progress from the central Great Lakes to the Northeast through tonight. Inversion heights will rise as 800-600 mb temperatures cool with passage of the trough later this afternoon. This combined with steep low-level lapse rates amid relatively warm lake temperatures of 8-10 C will support meager SBCAPE.
