EVENT...SW-NE BAND OF CNVTN INCRG ALONG SFC TROF
.
SATELLITE ANALYSIS AND TRENDS...SW-NE BAND OF CNVTN EXTENDS FM NE OF
DEC/IL TO SW SAGINAW BAY. SFC PLOTS AND OBJECTIVE ANALYSIS SHOWS THAT THIS
BAND HAS FORMED WITHIN ZONE OF SFC CONVERGENCE ASSOCD WITH SFC TROF. WHILE
THE CNVTN OVER LOWER MI/N INDIANA IS MOVG EWD..THE PORTION OVER IL AND
AND WRN INDIANA IS MOVG AT A SLOWER PACE. THERE..THE INDIVIDUAL CELLS
ARE MOVG..BUT THE BAND HAS SHOWN ONLY A SLIGHT EWD DRIFT AT BEST. IN
FACT..OUTFLOW FM MO/W IL IS RAPIDLY MOVG TWD THE E AND NE..AND WILL LIKELY
RESULT IN SOME BACKBUILDING OF THE WRN EDGE OF THE BAND NOW LOCATED NE
OF DEC. A SECOND BAND OF CNVTN IS BEGINNING TO DEVELOP OVER IL..JUST TO
THE S OF THE IL/IN/MI BAND..IN RESPONSE TO CONVECTIVE OUTFLOW FM W MO/W
IL FEEDING INTO CU/TCU LINES.
.
LATEST TREND DISCUSSED ABOVE SUGGESTS THAT A CELL TRAINING SITUATION
COULD BE SETTING UP ACRS THE AREA FM CENTRAL IL TO N CENTRAL IN. AS FOR
LOWER MI/N AND NE IN/NW OH...THUS FAR..THE CNVTN IS MOVG EWD. HOWEVER..THE
TSTM TOPS CONTINUE TO COOL TO VERY COLD LEVELS..AND ARE HEADED FOR SOME
AREAS THAT HAVE FFG VALUES BELOW 2". WITH THE INCRG INTENSITY OF THE
CELLS..IT IS PSBL THAT RAINFALL AMOUNTS COULD APPROACH OR REACH THOSE
VALUES. ADDITIONALLY...IT IS PSBL THAT SOME OF THE CNVTN NOW TO THE N
AND NE OF LAF..MAY MOVE INTO NE IN LATER ON.
