SATELLITE ANALYSIS AND TRENDS...IR IMAGERY SHOWS A FEW SMALL CLUSTERS
OF COLD TOP CELLS MOVING EWD ACROSS SE IA AND INTO W CENTRAL IL FROM NE
MO. THESE CELLS DO NOT APPEAR TO BE GREAT HVY RAINFALL PRODUCERS AS THE
CLUSTER OVER SE IA IS WARMING SLIGHTLY AND BECOMING MORE DISORGANIZED AS
IT MOVES E. HOWEVER SOME OF THE COLDEST TOPS IN BOTH THE CLUSTER OVER IA
AND THE ONE OVER W IL APPEAR TO BE STAYING RELATIVELY STNRY ON THE UPWIND
SIDE OF THE CLUSTER WITH CLOUD TOP TEMPS OF -70C OVER NE KEOKUK/IA AND
-73 OVER W GREENE COUNTY/IL. THESE CELLS ARE ON THE LEADING EDGE OF S/WV
ENERGY THAT PREVIOUSLY HAD INTENSIFIED THEKS MCS AS IT CROSSED FROM KS
TO S IA. DWPTS ON THE LEADING EDGE OF THE S/WV FROM SE IA TO W IL ARE
IN THE MID TO HIGH 60S WITH OBJECTIVE ANALYSIS INDICATING THETA-E AXIS
NOSING ACROSS NE MO ALMOST DIRECTLY BETWEEN THE TWO CLUSTERS SEEN IN
IR. PROFILERS SHOW SURPRISINGLY STRONG 35 KT WRLY 850MB FLOW PRESENT
OVER NW MO AND 30-35 KT SWRLY FLOW FROM SE KS JUST E OF THE MCS THAT
IS LIKELY CONVERGING OVER NE MO. FROM THIS SOME NEW CELLS HAVE BEGUN
TO FILL IN BETWEEN THE TWO CLUSTERS AND SHOULD CONTINUE THIS TREND AS
STORMS MOVE E. CELLS SHOULD CONTINUE TO PROGRESS WITH THE S/WV MOVEMENT
BUT ANY THAT DO STAY HELD BACK TO THE W WILL BE PROBLEMATIC GIVEN THE
FAIRLY DEEP CNVGING LOW LVL MOISTURE AND LOWER FFG.

SEE WEB ADDRESS IN ABOUT 5 MIN. SHOWING MAX 1 HR ESTIMATED AMOUNTS OF 1.3"
OVER THE WASHINGTON/KEOKUK BORDER. SLTL ESTIMATES INCORRECTLY PICKED UP
ON COLD TOPS OVER NW MO/SW IA WHICH WAS CIRRUS BLOWOFF FROM MCS TO THE
SW BUT HAVE DONE OK WITH THE NEW DVLPMT IN SE IA/W IL.
