...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are unlikely through tonight.

...Discussion...
No changes have been made to the ongoing thunder area near the West
Coast. Very low-topped convection from Grays Harbor northward along
the WA coast may contain weak, transient circulations this afternoon
over the offshore waters amid strong low-level shear. Instability on
land is expected to remain too flimsy to support a brief tornado
risk.

.PREV DISCUSSION... /ISSUED 1028 AM CST Fri Nov 22 2024/

...Synopsis...
A relatively dry and stable air mass is present over a large part of
the CONUS today, preventing thunderstorm potential in most areas.
The one exception will be associated with a deep upper low off the
Pacific Northwest coast.  Strong onshore flow and cold temperatures
aloft will result in pockets of thunderstorms along the coastal
ranges and mountains of northern CA throughout the forecast period.
No severe storms are anticipated.
