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

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

....Synopsis...

A progressive upper pattern is forecast on Thursday. A large-scale
upper trough will spread east over the eastern U.S., while another
upper trough moves inland over the Pacific Coast States. Meanwhile,
an upper ridge over the Rockies/Four Corners vicinity will track
east to the Plains.

A surface cold front is expected to be extend just offshore from the
Mid-Atlantic/coastal Carolinas vicinity into north/central FL and
the eastern Gulf of Mexico. A dearth of boundary-layer moisture in
the wake of the front, and building surface high pressure east of
the Rockies will preclude thunderstorm activity. A few lightning
flashes will be possible across central/southern portions of CA
ahead of the approaching mid/upper trough, and within a band of
strong west/southwesterly deep-layer flow and cool midlevel
temperatures. These storms are not expected to be severe given
meager instability and a relatively cool boundary layer.
