LATEST DATA USED: GOES-EAST:0545Z  JS

LOCATION...EAST CENTRAL TO NE SOUTH DAKOTA

.
EVENT...SOME CELL TRAINING CONTINUES ACROSS E CENT SD WITH APPROXIMATE
4 HOUR AUTOMATED SATELLITE ESTIMATES IN THE 2-3" RANGE WITH LOCALIZED
AMOUNTS OVER 4".
.
SATELLITE ANALYSIS AND TRENDS...AUTOMATED SATELLITE ESTIMATED TOTALS FOR
APPROXIMATELY THE PAST 4 HOURS INDICATE A SWATH OF 2-3" STRETCHING ACROSS
SANBORN/BEADLE/CLARK COUNTIES WITH ISOLATED TOTALS OVER 4" PARTICULARLY
OVER BEADLE COUNTY WHICH EXCEEDS THE APPARENT 3 AND 6 HOUR FFG VALUES
OVER THIS REGION. RECENT IR IMAGERY/RADAR COMPOSITE LOOPS SHOW ACTIVITY
BECOMING ELONGATED ALONG A SSW TO NNE AXIS WITH CELL TRAINING CONTINUING
TO OCCUR ACROSS PORTIONS OF THE ABOVE MENTIONED COUNTIES. ANALYSIS OF
THE SITUATION SHOWS MCV MOVING NORTHWARD APPROACHING THE ND/SD BORDER
WITH CONVERGENCE MAXIMIZED ALONG THE SE PORTION OF THE MCS. 60 DEGREE
PLUS SFC DEWPOINT AXIS IS NOSING NORTHWARD ACROSS E NEB INTO E SD
WITH GOES SOUNDER DATA INDICATING SLIGHTLY OVER 1" PW VALUES PRESENT
NEAR THE CONVECTION. THIS MOISTURE AVAILABILITY ALONG WITH CLOUD TOP
TEMPERATURES/TRENDS SUGGEST RAINFALL RATES OF AT LEAST 1.0-1.5"/HR WITH
THE STRONGEST CELLS. WITH RECENT TRENDS BEING VERY CONSISTENT, BELIEVE
THAT HEAVY RAINFALL THREAT WILL CONTINUE TO GRADUALLY SHIFT NORTHWARD
INTO NE SD COUNTIES SUCH AS DAY/ROBERTS/MARSHALL.
