SRN ILLINOIS. KILN RADAR SHOWS CONVECTION SKIRTING WEST CENTRAL
OHIO AND WAYNE COUNTY (IN). SATELLITE IMAGERY SHOWS BEST CLOUD
COVER OVER WEST CENTRAL OHIO.

MODELS ARE IN PRETTY GOOD AGREEMENT WITH BRINGING COLD FRONT

OUTFLOW AND MAINLY DURING PEAK DAYTIME HEATING. HAVE LEFT SMALL
POPS IN MONDAY AS FRONT MAY NOT MAKE IT SOUTH OF FA.

MAV AND MET TEMPS SEEM A LITTLE COOL. BELIEVE IT IS DUE TO THE

PERSISTENCE.
