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

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

....Discussion...
An upper-level trough is forecast to shift eastward/southeastward
across the Great Lakes and Midwest Friday, with surrounding cyclonic
flow expanding with time to cover much of the eastern half of the
country by the end of the period.  Meanwhile, ridging will prevail
across the West.

At the surface, a reinforcing surge of cold air is expected to
spread southward across the Plains, behind a cold front that should
extend from the Lower Great Lakes region southwestward to the
southern Plains by late afternoon.  By Saturday morning, the front
should extend from the East Coast States to the Gulf of Mexico.

Owing to meager instability at best ahead of the advancing cold
front, thunderstorm activity is forecast to be limited, with
severe-weather potential essentially non-existent.  A few
thunderstorms will be possible across the Great Lakes region within
scattered showers associated with the advancing system, with an
isolated storm also possible over Deep South Texas, and a small
portion of southeastern Arizona.  Elsewhere, inland thunderstorms
are not expected.
