.
EVENT...BOUNDARY ON WHICH ELEVATED CONVECTION CONTINUES TO DEVELOP HAS
REMAINED NEARLY STATIONARY FOR PAST FEW HOURS.
.
SATELLITE ANALYSIS AND TRENDS...IR LOOP DURING PAST COUPLE OF HOURS STILL
SHOWS SEVERAL BATCHES OF COOLER CLOUD TOPS ACROSS SOUTH DAKOTA. THE BEST
ENHANCEMENT HAS BEEN WITH THE ACTIVITY OVER SE SD MOVING FROM DOUGLASS
INTO HUTCHINSON COUNTY WHERE 3 HOUR AUTOMATED SATELLITE ESTIMATES ARE
IN THE 2-4" RANGE. IMAGERY THROUGH 0515Z STILL SHOWS A GOOD WEDGE TYPE
SIGNATURE WITH THIS ACTIVITY AS NEW DEVELOPMENT ON THE UPWIND END IS
FAVORED. TO THE NORTH OF THERE AN ELEVATED BOUNDARY SEEN ON COMPOSITE
RADAR LOOP WITH NW TO SE ORIENTED LINE OF REFLECTIVITIES STRETCHING
FROM AROUND SULLY COUNTY TO JERAULD/SANBORN COUNTIES CONTINUES TO BE THE
FOCUS FOR REGENERATING CONVECTION. SOME IR SATELLITE PRESENTATION IS ALSO
INDICATED WITH THIS LINE ALTHOUGH IT IS NOT AS PRONOUNCED AS AREA TO THE
SE. AUTOMATED SATELLITE ESTIMATES FOR THE PAST SEVERAL HOURS ALONG THIS
AXIS ARE SHOWING PATCHES OF 2" AND LOCALLY HIGHER TOTALS. WITH AREAS OF
UPSTREAM CONVECTION STILL EVIDENT ON SATELLITE/RADAR OVER SW AND S CENT
SD BELIEVE THAT ENTIRE AREA AFFECTING CENT TO E SD WILL BE VERY SLOW TO
MOVE TO THE EAST. THEREFORE EXPECT A CONTINUING THREAT OF ADDITIONAL
HEAVY RAINFALL FOR AT LEAST THE NEXT COUPLE OF HOURS ACROSS CENT TO E
AND SE SD LIKELY IMPACTING SOME OF THE SAME SPOTS ALREADY AFFECTED BY
HEAVY RAINFALL THIS EVENING.
