....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorms are not expected Tuesday.

....Synopsis...

An upper shortwave trough will pivot east/northeast across the
Midwest to the Northeast on Tuesday. A surface low will track in
tandem with the upper trough/low, with an attendant cold front
sweeping east across the MS/OH Valleys through evening. A dearth of
boundary-layer moisture will preclude much instability, except for
some modest dewpoints (mainly 40s to low 50s F) across the
Mid-Atlantic and Carolina coasts. As ascent increases with the
approach of the surface cold front and upper trough during the
evening, a couple of lightning flashes will be possible from the
upper OH Valley to the DelMarVa and coastal NC given very weak
MUCAPE (less than 150 J/kg). Overall, thunderstorm potential is
expected to remain very low, precluding a general thunderstorm
delineation.
