...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF
SOUTHWEST LOWER MICHIGAN AND NORTHERN INDIANA...

...SUMMARY...
A line of thunderstorms capable of producing strong to locally
damaging wind gusts will continue for a few more hours this evening
across parts of southwestern lower Michigan into northern Indiana.

...01z Update -- Lower Michigan into Indiana...

The Slight risk has been expanded eastward across parts of
southwestern lower Michigan and northern Indiana. A well-organized
line of storms with a history of wind gusts between 50-60 kt over
the past 1-2 hours continues to track eastward this evening. This
line of storms currently extends from southeastern portions of Lake
Michigan southwestward into eastern IL. At least a brief period of
severe potential will extend downstream where weak instability and
strong shear is present. With time and eastward extent, the boundary
layer should begin to stabilize with loss of daytime heating, and
stronger forcing will begin to lift north/northeast of the area,
lessening severe potential.

Otherwise, the only other changes at 01z were to remove the Marginal
risk across Florida where severe potential has decreased this
evening, and to adjust the 10% general thunder line per latest
observational trends.
