Day 3 Convective Outlook 
NWS Storm Prediction Center Norman OK
0106 PM CST Wed Nov 20 2024

Valid 221200Z - 231200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated to scattered thunderstorms are possible along the Pacific
Northwest Coast on Friday.

...Synopsis...
A large upper low will start to move off the East Coast on Friday.
In its wake, a dry/cool continental airmass will overspread the
eastern CONUS which will result in no thunderstorm threat.

...Pacific Northwest Coast...
Cooling air aloft across the northeast Pacific, associated with the
approaching mid-level trough, will lead to enough instability over
the water to support some thunderstorm activity. Some of these
thunderstorms may impact coastal areas during the day on Friday.
Very strong synoptic winds are likely along the coast as a sub-990mb
low moves north along the coast. Thunderstorm activity could enhance
some of these winds and lead to increased wind damage threat, but
instability is too limited for a marginal risk at this time.
