Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0643 PM CST Thu Nov 05 2020

Valid 060100Z - 061200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected across the contiguous U.S.
tonight.

...01z Update...

No changes to the 20z outlook are warranted.

Strong upper low off the Pacific Northwest Coast is digging toward
OR/northern CA. Cold mid-level temperatures associated with this
feature will move onshore by the end of the day1 period enabling
weak convective development beneath the upper trough. Some of the
stronger convection may produce a few flashes of lightning.

Higher-PW air mass that was suppressed south of the FL Straits is
beginning to advance a bit north-west into south FL this evening,
per 2 inch PW observed at MFL at 00z. While isolated thunderstorms
are primarily focused offshore, some thunder potential remains
across south FL extending north along the SC Coast.
