...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not forecast today, with only an early
morning chance of thunderstorms near the Mid Atlantic Coast.

...Synopsis and Discussion...
A deepening upper low will move east from the OH Valley into New
England today, with the upper trough sweeping eastward toward the
Atlantic Coast by evening. Northwest flow aloft will then exist in
the wake of this trough, from the Plains to the East Coast into
Monday.

At the surface, low pressure will be located over southeast VA at
12Z this morning, and will deepen as it moves quickly offshore.
Strong and veering low-level winds will push the cold front offshore
as well, with a maximum of 1-2 hours of warm sector over land from
southeast VA into the eastern Carolinas this morning.

Weak instability, perhaps up to 250 J/kg, may briefly support a few
strong storms near the low or just south prior to moving offshore.
Gusty winds may accompany any frontal convection as low-level SRH
weakens due to the rapidly veering surface flow.
