...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected through Sunday morning.

...Synopsis...
A stable pattern in terms of thunderstorm potential will exist
today, with high pressure over much of the CONUS. An upper trough
will move out the Mid Atlantic and Northeast, with a surface low and
cold front pushing well offshore. Behind this front, offshore flow
over the Gulf of Mexico and western Atlantic will maintain stable
conditions.

Elsewhere, a large upper trough will drop into the Western CONUS,
with cooling aloft steepening lapse rates. Little to no convective
instability is forecast, and as such thunderstorms are not forecast.
