Valid 201200Z - 211200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorm development will be possible on Thursday in parts of
the Mid-Atlantic and northern Rockies. A severe threat is not
expected.

....DISCUSSION...
At mid-levels on Thursday, a trough will move across the Ohio and
Tennessee Valleys, as a fetch of southwest flow strengthens along
the East Coast. At the surface, a pre-frontal trough will move
across the Atlantic Coastal Plains. Ahead of the front, surface
dewpoints are expected to reach the 50s F across the Mid-Atlantic,
where weak destabilization will occur. Forecast soundings near the
moist axis Thursday afternoon in central Virginia have MUCAPE
peaking around 250 J/kg. As the exit region of the mid-level jet
passes by, 0-6 km shear is forecast to be in the 80 to 90 knot
range. Although thunderstorms will be possible across parts of the
Mid-Atlantic Thursday afternoon, the instability is expected to be
too weak for a severe threat.

Elsewhere, isolated thunderstorms will be possible ahead of a
shortwave mid-level trough, across parts of the northern Rockies and
northern High Plains. No severe threat is expected across the
continental U.S. Thursday and Thursday night.
