SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1201 PM CDT Thu Oct 29 2020 Valid 301200Z - 311200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Only a few weak thunderstorms are possible over southern Florida on Friday. ...Synopsis... As a large upper trough lifts across the Great Lakes and Northeast, high pressure will encompass the eastern CONUS with offshore flow over the Gulf of Mexico and western Atlantic. This will shunt any appreciable low-level moisture mostly offshore, the exception being far southern Florida where 70s F dewpoints will remain. Here, daytime heating and weak convergence may lead to an isolated thunderstorm or two during the afternoon. Elsewhere, a shortwave trough will drop east/southeast across the Pacific Northwest and into the northern High Plains by Saturday morning resulting in lift, but little if any instability will be present for lightning. ..Jewell.. 10/29/2020
