....THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE LOWER
OHIO VALLEY...

....SUMMARY...
Scattered strong to severe thunderstorms remain possible across
parts of the lower Ohio Valley tonight.

....01z Update...

Upper low currently centered near the southern tip of Lake MI is
drifting east in line with latest model guidance. Strongest
mid-level flow extends across the lower MO Valley into western
KY/TN, and substantial cyclonic flow is now well established over
the OH Valley. Over the last few hours showers have gradually
increased along a weak wind shift from central IN, arcing southwest
across southern IL into southeast MO. Models continue to suggest
this activity will continue to increase in intensity and areal
coverage this evening. LLJ is also forecast to increase across
western KY which should support upward growth. Hail/wind are the
primary risks with this activity.
