THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 446
CONTINUES.

SUMMARY...NUMEROUS TSTMS ARE ONGOING ACROSS LOWER MI AND N-CNTRL
IND...WITH SEVERAL EXHIBITING THE POTENTIAL FOR PRODUCING LARGE HAIL
AND DMGG WIND GUSTS. THREAT SHOULD DECREASE FROM THE W IN THE WAKE
OF A COLD FRONT ACROSS IND PORTION OF THE WATCH...WHILE ADDITIONAL
STRONG STORMS WILL MOVE ONSHORE FROM LM INTO WRN LOWER MI THE NEXT
1-2 HRS.

DISCUSSION...NUMEROUS /MOSTLY DISCRETE/ STORMS...INCLUDING
SUPERCELLS...ARE CURRENTLY ONGOING ACROSS LOWER MI AND NERN IND.
CONVECTIVE DEVELOPMENT IS GENERALLY FOCUSED NEAR A SFC LOW OVER
CNTRL MI...AND ALONG/AHEAD OF AN ATTENDANT COLD FRONT PROGRESSING
EWD ACROSS CNTRL IND AND WRN LOWER MI. SEVERAL REPORTS OF LARGE HAIL
/UP TO GOLFBALL SIZE/ HAVE BEEN ASSOCIATED WITH THESE STORMS...AS
WELL AS STRONG TO MARGINALLY SVR WIND GUSTS. THESE WILL REMAIN THE
PRIMARY THREATS THROUGH THE EARLY EVENING AS ACTIVITY GENERALLY
SHIFTS EWD.

TSTM POTENTIAL DECREASES RAPIDLY IN THE WAKE OF THE COLD FRONT OVER
CNTRL IND...WHERE MUCH DRIER AIR IS ADVECTING EWD. ACROSS LOWER
MI...ADDITIONAL STRONG STORMS HAVE DEVELOPED W OF THE COLD FRONT IN
ASSOCIATION WITH MIDLEVEL COLD POCKET ACCOMPANYING AN INTENSE UPPER
TROUGH. WHILE SVR POTENTIAL WITH THIS ACTIVITY MAY BE SOMEWHAT
REDUCED IN THE PRESENCE OF COOLER SFC TEMPERATURES AND DRIER
LOW-LEVEL AIR...A THREAT FOR HAIL AND STRONG WIND GUSTS MAY STILL
EXIST.
