EVENT...HEAVY RAINFALL WITH RAPIDLY DEVELOPING MCS
.
SATELLITE ANALYSIS AND TRENDS...OVER THE LAST SEVERAL HOURS CONVECTION
HAS DEVELOPED AND RAPIDLY ORGANIZED INTO A SMALL MCS VERY NEAR THE
MISSOURI VALLEY OF THE NORTH AND SOUTH DAKOTA BORDER.  MCS APPEARS AS
THOUGH IT HAS ORGANIZED IN AN AREA OF MAXIMUM 85H THETA-E ADVECTION
JUST NE OF 85H THETA-E RIDGE AXIS.  SYSTEM ALSO APPEARS TO BE DEVELOPING
VERY NEAR FAVORED MID LEVEL RIDGE AXIS PER LATEST WATER VAPOR IMAGERY.
MOST ACTIVE CONVECTION LOOKS AS THOUGH IT IS STRADDLING THE DAKOTA'S
BORDER FROM SE SIOUX/NE CORSON COUNTIES TO S EMMONS/N  CAMPBELL COUNTIES.
RAPIDLY COOLING CLOUD TOPS LOOK AS THOUGH THEY ARE CENTERED OVER THE FOUR
COUNTIES MENTIONED ABOVE AND ALSO FURTHER ESE IN MCPHERSON COUNTY WHERE
CONVECTIVE CELLS APPEAR TO BE MERGING INTO THE LARGER SCALE COMPLEX.
GOES DERIVED DIGITAL TPW'S RANGING FROM 1.20-1.40" AND THESE VALUES
ALONG WITH THE TENDENCY FOR SLOW MOVING/TRAINING CELLS SHOULD ALLOW FOR
SOME LOCAL RAINFALL RATES OF UP TO 2.0"/HR IN THE MOST INTENSE CORES.
SHEAR VECTORS SUGGEST THAT MOST ACTIVE CONVECTION ASSOCIATED WITH MCS
SHOULD MOSTLY TAKE AN EWARD HEADING OVER THE NEXT FEW HOURS.  THIS SHOULD
CONTINUE TO SPREAD LOCALLY HEAVY RAIN ALONG THE NORTH/SOUTH DAKOTA BORDER
COUNTIES OF MCINTOSH/DICKY/BROWN/MCPHERSON OVER THE NEXT HOUR OR SO.
WILL CONTINUE TO MONITOR.
