Valid 010100Z - 011200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE MIDDLE ATLANTIC...RED RIVER REGION OF THE SOUTHERN
PLAINS...SOUTHWESTERN  BORDER AREA...AND PACIFIC NORTHWEST...

...SUMMARY...
Isolated strong, to locally severe, thunderstorms will persist for a
few hours this evening. Damaging gusts are the primary concern.

...01z Update...

Diurnal heating, and steepening of the boundary layer, has been the
primary instigator for scattered convection across much of the CONUS
this afternoon. Many areas have been efficiently overturned and with
onset of nocturnal cooling, further stabilization is expected this
evening. Even so, for the next few hours a few pockets of robust
convection will likely persist. Moderate to strong buoyancy is noted
across the Delmarva and the Red River region of southern OK/north
TX. Deep convection may continue to generate locally strong winds
until this activity weakens by mid evening.

Isolated wind gusts may also accompany high-based convection across
southeast AZ/southern NM, and near the OR/CA border. Boundary-layer
cooling will also contribute to further weakening, along with a
lessening severe threat.
