...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE CENTRAL HIGH PLAINS AND MID-ATLANTIC...

...SUMMARY...
A few strong storms capable of large hail and damaging wind gusts
are possible in portions of the Colorado/Wyoming Front Range and
storms capable of damaging wind gusts are possible in the
Mid-Atlantic.

...Synopsis...
Upper-level ridging will continue to strengthen across the central
US on D2/Thursday. A belt of enhanced westerly flow moving through
the trough across southeastern Canada will overspread a cold front
across portions of the Mid Atlantic. The surface cold front will
extend from the Mid-Atlantic back into the Southern Plains.

...Central High Plains...
Afternoon thunderstorm development is expected across the high
terrain in Wyoming and northern Colorado. Across this region, steep
low to mid-level lapse rates and sufficient shear around 25-35 kts
will support potential for a few supercells. These storms would be
capable of strong to severe wind and some instances of large hail as
they move out of the high terrain.

...Mid-Atlantic...
Thunderstorm activity is expected to increase near and south of the
surface cold front in the Mid-Atlantic on Thursday afternoon.
Enhanced flow from the trough will support deep layer shear around
30-40 kts. Mode will likely be mixed with multi-cell clusters
developing by the late afternoon. Deep moisture and moderate MLCAPE
south of the front will support potential for strong to severe winds
from wet downbursts.
