SPC Nov 12, 2021 0830 UTC Day 3 Severe Thunderstorm Outlook

SPC 0830Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0100 AM CST Fri Nov 12 2021 Valid 141200Z - 151200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast across the contiguous United States on Sunday. ...Synopsis and Discussion... A large-scale upper trough will remain over much of the eastern CONUS on Sunday. A pronounced mid-level shortwave trough embedded within the large-scale troughing should move eastward across the OH/TN Valleys through the day, eventually reaching the East Coast by the end of the period. Due to multiple prior frontal passages, substantial low-level moisture should remain confined over the Gulf of Mexico and far south FL. Accordingly, instability is currently forecast to remain nil ahead of the eastward-progressing shortwave trough, with minimal thunderstorm potential apparent across the CONUS on Sunday. ..Gleason.. 11/12/2021 Read more LIVE: spc.noaa.gov
