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

....SUMMARY...
Severe thunderstorms are not expected on Thursday.

....Synopsis...

An upper trough will lift northeast over New England on Thursday
while a shortwave upper trough weakens while shifting from the
southern Plains to the Lower MS Valley. Meanwhile, a low-amplitude
upper trough will move across the Pacific Northwest. A dearth of
boundary-layer moisture is forecast in the wake of a cold frontal
passage in the Day 2/Wed time period. However, midlevel moisture
will increase across parts of TX into the Lower MS Valley ahead of
the Plains shortwave trough. Modest midlevel lapse rates will also
be present, providing support for weak elevated instability
overnight. This should allow for isolated thunderstorms from east TX
into parts the Lower MS Valley, though severe storms are not
expected. Additional isolated thunderstorms are possible as the
upper trough moves inland across the Pacific Northwest.
