SATELLITE ANALYSIS AND TRENDS...EARLIER MCS WHICH MOVED ACROSS SOUTHERN
AND CENTRAL SOUTH DAKOTA IN FAVORABLE ANALYZED 850MB THETA-E RIDGE AXIS
HAS APPARENTLY SET DOWN A OUTFLOW BOUNDARY. THIS BOUNDARY IS NOW BEING
ACTED ON BY INCREASING SOUTHWESTERLY LOW LEVEL JET AS SEEN IN PAST COUPLE
OF HOURS OF DATA FROM THE CHERRY COUNTY NEB PROFILER SITE. NEW CELLS
HAVE FORMED ON THE WESTERN PORTION OF THE ORIGINAL MCS AND APPEAR TO BE
TRAINING AT LEAST TO SOME EXTENT ACROSS PORTIONS OF JACKSON/MELLETTE/TRIPP
COUNTIES. RAPID EXPANSION OF CLOUD TOPS ALONG WITH ADEQUATE MOISTURE
AVAILABILITY (PWS SLIGHTLY OVER 1"/SFC DEWPOINTS MID-UPPER 50S) ARE
LEADING TO SATELLITE ESTIMATED RATES OF 1.0-1.5"/HR WITH THE STRONGER
CELLS. SOME OF THIS REGION WAS AFFECTED BY EARLIER MCS SO THE ADDITIONAL
RAINFALL COULD APPROACH THE APPARENT AVERAGE 3 HOUR FFG VALUES (NEAR
3"). ANNOTATED SATELLITE GRAPHIC SHOWING ANALYZED FEATURES SHOULD BE
AVAILABLE ON THE INTERNET SITE LISTED BELOW IN APPROXIMATELY 10 MINUTES.
