...Mid MS Valley into Great Lakes...
Fast zonal flow is present today across much of the nation.  At the
surface, the primary baroclinic zone extends from TX/OK into OH. 
This boundary will provide the focus for relatively widespread
showers and thunderstorms this afternoon and tonight from parts of
MO/IA into IL/WI/IN/MI.  These storms will be elevated above a
relatively stable surface layer, but in region of rather cold
temperatures aloft.  Small hail is possible in the stronger cells,
but severe storms appear unlikely.

Elsewhere across the nation, scattered storms are possible over
parts of FL and southern GA, and isolated lightning strikes will be
possible over parts of TX and the northeast states.
