NWS STORM PREDICTION CENTER NORMAN OK
0628 PM CDT SAT JUL 23 2016

AREAS AFFECTED...SWRN LOWER MI THROUGH NRN IND

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 232328Z - 240130Z

PROBABILITY OF WATCH ISSUANCE...20 PERCENT

SUMMARY...STORMS CROSSING SRN LAKE MI MAY POSE AT LEAST A MODEST
THREAT FOR ISOLATED DAMAGING WIND GUSTS THIS EVENING. HOWEVER...THE
THREAT IS NOT EXPECTED TO BECOME SUFFICIENT FOR A WW.

DISCUSSION...CLUSTER OF POORLY ORGANIZED STORMS IS MOVING SLOWLY
ESEWD THROUGH SRN LAKE MI. THIS ACTIVITY IS DEVELOPING WITHIN ZONE
OF ISENTROPIC ASCENT NORTH OF A STATIONARY FRONT THAT EXTENDS
THROUGH NRN IND INTO NRN OH. THE STORMS WILL LIKELY CONTINUE ESEWD
AND AFFECT SWRN LOWER MI AND NRN IND WHERE THE ATMOSPHERE IS
MODERATELY UNSTABLE. HOWEVER...PRIMARY LLJ WILL REMAIN WEST OF THIS
REGION...AND 0-6 KM VERTICAL SHEAR IS WEAK...SUGGESTING STORMS
SHOULD REMAIN POORLY ORGANIZED. NEVERTHELESS...A FEW STRONG TO
DAMAGING WIND GUSTS CANNOT BE RULED OUT BEFORE THE ACTIVITY
GRADUALLY WEAKENS LATER THIS EVENING.
