SPC Nov 28, 2021 1630 UTC Day 1 Convective Outlook

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. While alignment of wind vectors will largely orient more perpendicular to the lake with time, the favorable thermodynamic profile should favor potential for a few lightning flashes in bursts of convective snow showers during the late afternoon and early evening. ..Grams/Lyons.. 11/28/2021 Read more LIVE: spc.noaa.gov
