...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected today and tonight.

...Synopsis and Discussion...
Elevated thunderstorms ongoing across west-central IL should
continue for a few more hours this morning, aided by modest warm
advection in the 850-700 mb layer and ascent on the southern
periphery of a shortwave trough over the Upper Midwest. With a
mainly linear mode now dominant, severe hail appears unlikely. This
activity should gradually diminish in coverage and intensity through
the remainder of the morning.

Isolated to scattered thunderstorms will be possible today from
parts of the Mid-Atlantic southwestward to the Gulf Coast/Southeast.
Weak flow and related deep-layer shear will limit the overall severe
threat with any convection that develops across these regions. A
pronounced shortwave trough will move across the Pacific Northwest
and northern Rockies/Plains through tonight. While large-scale
forcing and mid-level flow associated with the upper trough passage
will be strong, thunderstorm coverage is expected to remain sparse
due to a rather dry airmass present across these areas.
