AREAS AFFECTED...NRN IL/SRN WI

CONCERNING...TORNADO WATCH 566...

VALID 060229Z - 060330Z

SQUALL LINE NOW MOVING INTO NWRN IL MAY REMAIN SEVERE FOR A SHORT
TIME AFTER THE WATCH EXPIRES...BUT A NEW WW IS NOT ANTICIPATED. 00Z
SOUNDING FROM ILX SUGGESTS AIRMASS ACROSS SRN WI AND NRN IL IS NOT
AS UNSTABLE...WITH TEMPS ONLY IN THE 60S...AND AIRMASS IS DRIER
FARTHER EAST INFLUENCED BY A LAKE BREEZE THAT HAS BEEN ADVECTED
INLAND FROM LAKE MICHIGAN. HOWEVER...FAVORABLE LOW LEVEL AND DEEP
LAYER SHEAR WILL CERTAINLY SUPPORT A THREAT FOR EMBEDDED SUPERCELLS
WITHIN THE LINE. THE NRN END OF THE LINE IS EXPECTED TO
WEAKEN...WHILE THE SRN PART OF THE LINE MAY MAINTAIN
ITSELF...ESPECIALLY IF STRONG FORWARD PROPAGATION CONTINUES AND
STORMS CAN MOVE SOUTHEAST WHERE THE AIRMASS IS MORE UNSTABLE. SEVERE
THREAT IS EXPECTED TO GRADUALLY DIMINISH OVER THE NEXT COUPLE OF
HOURS.
