SPC Nov 10, 2021 0830 UTC Day 3 Severe Thunderstorm Outlook

SPC 0830Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0155 AM CST Wed Nov 10 2021 Valid 121200Z - 131200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Friday. ...Synopsis... An upper low and attendant trough will pivot eastward across the Midwest and Southeast on Friday. At the surface, a cold front will extend from western NY south/southwestward toward the FL Panhandle. The front will move offshore the Atlantic coast by late afternoon, arcing across the FL peninsula and into the northern Gulf. Limited heating due to cloud cover and widespread precipitation near/ahead of the front, and poor midlevel lapse rates, will preclude severe thunderstorm potential across the eastern Carolinas into the Mid-Atlantic. Better quality boundary-layer moisture will reside over southern FL, resulting in MLCAPE values approaching 750-1000 J/kg. However, large-scale ascent and vertical shear will remain weak with poor low-level convergence near the surface boundary and severe thunderstorms are not expected. ..Leitman.. 11/10/2021 Read more LIVE:
