EVENT...SEVERAL ROUNDS OF STORMS TRAINING ACROSS S IA/N IL/N IN
.
SATELLITE ANALYSIS AND TRENDS...NUMEROUS CLUSTERS OF CELLS ARE MOVING
W-E ALONG THE NRN EDGE OF THE THETA-E AXIS FROM S MO THROUGH N IL
INTO NRN IN. THESE TRAINING CELLS ARE PRODUCING HVY RAINS OVER ALREADY
SATURATED AREAS THAT HAVE SEEN STORMS FOR THE PAST FEW DAYS. STRONGEST
CELLS ARE SEEN IN SRN IA JUST BARELY N OF THE MO BORDER WHERE CLOUD TOP
TEMPS ARE AROUND -75 TO -77C AS THE RESULT OF MERGING CELLS WITHIN THE
CLUSTER. OBJECTIVE ANALYSIS SHOWS GOOD MOISTURE CNVG OVER THE IA/MO BORDER
EXTENDING SWD AND ALONG WITH THIS..LATEST STLT TRENDS SUGGEST THAT THE
CLUSTER WILL SLIP INTO N/CENTRAL MO OVER THE NEXT HR OR TWO. ADDITIONAL
STORMS BUILDING NEWD OUT OF SE NE LOOK AS THOUGH THEY WILL TAKE THE
PLACE OF THE CLUSTER CURRENTLY IN S IA AND FILL IN TO ITS N. NEXT S/WV
IN THE FLOW IS CURRENTLY SEEN IN W CENTRAL KS PER WV IMAGERY AND WILL
BE SOMETHING TO KEEP AN EYE ON AS IT WILL BE AFFECTING IA/MO PROBABLY
AROUND 12Z.
.
NEW TSTORMS HAVE FORMED OVER N IL AGAIN IN THE WAKE OF CELLS TO THE E
THAT HAD MOVED THROUGH EARLIER BUT WEAKENED AS THEY MOVED INTO SLIGHTLY
DRIER/MORE STABLE AIR ACROSS SERN MI/N OH/NE IN. BELIEVE WILL SEE THIS
PATTERN CONTINUE FOR THE NEXT FEW HRS AS THETA-E AXIS EXTENDS INTO CENTRAL
IL BEFORE TAKING A N/NEWD TURN TWDS SFC LOW IN S WI. IMPULSE THAT IS
CURRENTLY OVER N IN IS THE SAME THAT CAUSED THE HVY RAINS LAST NIGHT IN SE
SD AND NERN NE BUT AS SAID ABOVE IS RUNNING INTO A DRY POCKET OF AIR. 00Z
SOUNDING FROM DVN SHOWED NEARLY UNIDIRECTIONAL FLOW THROUGHOUT THE LAYER
WHICH SHOULD ALLOW FOR VERY EFFICIENT HVY RAIN PROCESSEES THROUGHOUT
THE NIGHT. 1 HR AUTO ESTIMATOR AMOUNTS ENDING 0345Z SHOWED A 1.5-2"
AREA IN SE IA WITH A MAX OF 2.2" AND ANOTHER MAX OF 1.7" IN LA SALLE
COUNTY IN N IL. SEE WEB ADDRESS IN ABOUT 5-10 MIN FOR ESTIMATES GRAPHIC.
