THREAT OF DAMAGING WINDS CONTINUES WITH CONVECTIVE LINE MOVING
320/35KT THROUGH CENTRAL/S-CENTRAL IND AND FAR ERN IL. WW 659
CONTINUES IN EFFECT ACROSS THE REGION THROUGH 22/07Z.

IND 88D IMAGERY CONTINUES TO INDICATE A WELL-ORGANIZED CONVECTIVE
LINE WHICH HAS ACCELERATED SEWD DURING THE LAST 1-2 HOURS IN
RESPONSE TO STRENGTHENING COLD POOL. NARROW WEAK ECHO CHANNELS INTO
REAR OF STORMS AND LEADING OUTFLOW NEARLY COINCIDENT WITH STRONG
FORWARD REFLECTIVITY GRADIENT SUGGEST DAMAGING WINDS ARE LIKELY WITH
THIS SYSTEM ACROSS THE WATCH AREA DURING THE NEXT FEW HOURS. AIR

DEWPOINTS IN THE UPPER 70S TO LOW 80S SOUTH OF ONGOING ACTIVITY.
MODERATE WNWLY DEEP-LAYER SHEAR AND STRONG LOW-LEVEL DIRECTIONAL
SHEAR SHOULD ALSO HELP MAINTAIN SEVERE CONVECTIVE LINE DURING NEXT
FEW HOURS.
