EVENT...MCS CONTINUES ITS STEADY ESE PROGRESSION WITH GENERALLY 1-2"
AUTOMATED SATELLITE ESTIMATED RAINS ACCOMPANYING IT.
.
SATELLITE ANALYSIS AND TRENDS...TRENDS HAVE BEEN FAIRLY CONSISTENT
WITH THE EVOLUTION OF THIS CONVECTIVE SYSTEM OVER THE PAST COUPLE OF
HOURS. SOME DEVELOPMENT HAS OCCURRED OUT AHEAD OF MAIN COMPLEX ACROSS
NORTH CENTRAL AND EASTERN IA BUT OVERALL QUICK MOVEMENT OF THE SYSTEM
HAS OFFSET THIS SOMEWHAT. HOWEVER THERE ARE STILL VERY STRONG CELLS
IN THE CORE OF THE MCS AS SEEN WITH VERY COLD/OVERSHOOTING TOPS IN
SATELLITE IMAGERY CAPABLE OF PRODUCING RATES IN EXCESS OF 2"/HR AND
ACTUAL TOTALS OF AT LEAST 1-2" (IF NOT LOCALLY OVER 2") IN A HOUR OR SO
WHICH EXCEEDS THE APPARENT THRESHOLD OF 1 HOUR AVERAGE FFG VALUES FOR
MUCH OF E IA. ACTIVITY IS HEADED TOWARD REGION OF LOWER FFG VALUES AND
INTO AREA OF HIGH MOISTURE POOLED ACROSS E IA/N IL WITH AXIS OF MID TO
UPPER 70F SFC DEWPOINTS SEEN FROM RECENT OBSERVATIONS.
