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.
