....THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM CENTRAL
ILLINOIS INTO SOUTHERN INDIANA...

....SUMMARY...
Isolated severe thunderstorms remain possible across central
Illinois into southern Indiana this evening. A few strong storms are
also expected across the central Plains from southeast Colorado into
northern Kansas.

....01z Update...

Weak MCS continues propagating south across eastern KY early this
evening. This complex of storms is reinforcing a boundary that is
draped from central KY-southern IN-central IL. Over the last hour or
so, strong storms have developed along this boundary over central IL
which should track southeast along/near the wind shift within modest
northwesterly flow but strong instability.

Upper anticyclone centered over the southern Plains continues to
redirect weak short-wave troughs around this feature across the Four
Corners into the central Plains. It appears the remnants of an old
tropical system are influencing clusters of strong convection across
southeast CO into northern KS. As the upper high slowly breaks down
and drifts west, steering currents may allow some of this activity
to spread across northern KS toward northern MO. Gusty winds are the
greatest risk.
