WW WILL BE ISSUED FOR PARTS OF NRN/CENTRAL IA.

REGIONAL RADARS INDICATED A COUPLE OF STRONG TO SEVERE STORMS HAVE
DEVELOPED ALONG A SURFACE BOUNDARY WHICH EXTENDED FROM NERN TO WRN
IA.  AIR MASS EAST OF THIS BOUNDARY IS VERY MOIST AND MODERATELY
UNSTABLE AND IS LOCATED WITHIN THE RIGHT ENTRANCE REGION OF A 50 KT
WLY MID LEVEL JET OVER THE GREAT LAKES.  ALTHOUGH STRONGER DEEP
LAYER SHEAR IS OVER SRN MN INTO NRN IA SUPPORTIVE FOR SOME SUPERCELL
POTENTIAL...MODERATE SHEAR /SFC-6 KM 20-25 KT/ FARTHER SOUTH INTO
CENTRAL IA WILL FAVOR MULTICELLS.  HAIL AND DAMAGING WINDS EXPECTED
TO BE THE PRIMARY THREATS AS SURFACE BOUNDARY MOVES EWD INTO
INSTABILITY AXIS.
