.
EVENT...UPPER LOW EXITING INTO HIGH PLAINS
.
SATELLITE ANALYSIS AND TRENDS...MAIN UPPER LOW QUITE EVIDENT ON
ALL SPECTRAL CHANNELS OVER NE WY WITH OLD SWIRL OVER E MT ALONG THE
DEFORMATION ZONE INTO NORTHERN ND TO NW MN WHERE MDT OVERRUNNING HAS
OCCURRED THROUGHOUT THE DAY.  WITH THE APPROACH OF THE UPPER LOW AND VERY
GOOD SOLAR HEATING ACROSS SD AND EXT S ND...CONVECTION HAS DEVELOPED ALONG
THE WARM FRONT WHERE THERE IS MAIXIMIZED SFC MOISTURE CONVERGENCE. WARM
SECTOR IS BEGINNING TO FILL IN BACK TOWARD THE UPPER LOW. CELLS ALONG
THE WARM FRONT APPEAR TO BE MOVING VERY SLOWLY  FURTHER EAST ALONG
THE FRONT...LETTING WESTERN CONVECTION CATCH UP AND MERGE WITH IT.
THIS IS MOST EVIDENT OVER SIOUX COUNTY ND WHERE THE OVERSHOOTING TOPS ARE
CONGEALING INTO A LARGER COMPLEX.  PWS ARE NOT TERRIBLY HIGH WITH VALUES
AROUND .8" AND SFC TDS IN THE 40S...SO IT WILL BE MERGING/TRAINING AND
SLOW MOTIONS THAT COULD LEAD TO HIGHER TOTALS...BUT IT APPEARS THAT THE
WARM FRONT SHOULD REMAIN STATIONARY ACROSS S ND AND THE LOW WILL ZIP
ALONG IT WITH THE BULK OF CONVECTION NEAR THE TRIPLE POINT ADDING TO
HIGH TOTALS ALONG THAT TRACK.
