Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0208 AM CST Wed Nov 20 2024

Valid 221200Z - 231200Z

...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorm activity will remain quite limited on Friday.

...Synopsis...
A deep upper low will begin centered over the PA/NY area, but within
a large, deep upper trough. Meanwhile, an upper ridge will exist
over the Rockies, shifting slowly east toward the High Plains by 12Z
Saturday. West of this ridge, height falls will occur over the
Pacific Northwest as a broad upper trough moves in.

High pressure will persist over much of the CONUS, the exception
being over the Northeast near the deep tropospheric cyclone, with a
dry air mass lacking of CAPE. The exception will be just off the
WA/OR coasts, where low-topped convection is possible over the
ocean, and perhaps near the coastline by 12Z Saturday.
