.
SATELLITE ANALYSIS AND TRENDS...TWO AREAS OF IMMEDIATE CONCERN FOR VERY
HVY RAINFALL ARE ACROSS NE MO/W-CENT IL BORDER AND THE OTHER ALONG THE
CENTRAL IL/IN STATE LINE.  NUMEROUS TSTMS HAVE DEVELOPED ALONG A SW-NE
AXIS (21Z SFC ANALYSIS ALSO SHOWS THAT HIGHEST MOISTURE IS COLLOCATED
WITH LINE OF CONVECTION WITH PW VALUES AOA 1.5") EXTENDING FROM N MO NEWD
THRU CENTRAL IL AND N IN.  ALONG THIS AXIS CONVECTION HAS DEVELOPED AND
INTENSIFIED RAPIDLY AS MID-LVL LIFT IS BEING PROVIDED BY EWD MOVING S/WV
ACROSS IA/SE MN/W WI.
.
VIS STLT IMAGERY SUGGESTS MERGER BETWEEN THREE DISTINCT CONVECTIVE CELLS
IS LIKELY WITHIN THE NEXT 30 MINS ACROSS NE MO..SE OF IRK/MO AND W OF
UIN/IL.  RAINFALL RATES ARE ESTIMATED TO BE BETWEEN 1.0-1.5"/HR..BUT
WITH CELLS EXPECTED TO MERGE THIS COULD RISE TO 2.0"/HR.  THE MERGED
CELL IS THEN EXPECTED TO CONTINUE MOVING EWD INTO W IL.
.
THE SECOND AREA OF CONCERN IS FOR TRAINING OF W-E MOVING CELLS ACROSS
LIVINGSTON/FORD/IROQUOIS COUNTIES IN W IL.  LATEST 1-HR AUTOMATED STLT
ESTIMATES INDICATE A MAX RAINFALL OF NEAR 1.0" OVER CENTRAL IROQUOIS
COUNTY.  LATEST IR IMAGERY AT 2145Z SHOWS SLIGHT WARMING OF CLOUD TOP
TEMPS ASSOCIATED WITH THE CELLS OVER THESE COUNTIES..YET TOPS REMAIN
COLD AROUND -66C.  AXIS OF HVY RAIN IS EXPECTED TO SHIFT SLIGHTLY S AND
E FROM ITS CURRENT POSITION AND GREATEST THREAT OF TRAINING MAY BE OVER
BENTON/WARREN/WHITE/TIPPECANOE/CARROLL COUNTIES IN W IN.
