Areas affected...Illinois

Concerning...Tornado Watch 696...

Valid 270532Z - 270730Z

The severe weather threat for Tornado Watch 696 continues.

SUMMARY...Strong thunderstorms, with some severe potential, will
spread across much of Illinois into the early morning hours. Locally
damaging winds, and perhaps a brief tornado are possible. New ww is
not currently anticipated.

DISCUSSION...Exit region of intense mid-level jet will spread across
the mid MS Valley region tonight. This focused zone of ascent should
encourage convection along northern edge of recovering warm sector.
Latest radar/lightning data supports this with scattered strong
thunderstorms noted ahead of surface low from southeast IA, arcing
across northwestern IL - west central IL. This activity should
spread northeast within a highly diffluent flow regime, but should
advance beyond the most buoyant corridor of instability over the
next few hours. Locally strong wind gusts are the primary threat,
though a brief tornado can not be ruled out where surface dew points
have risen into the upper 50s.
