SATELLITE ANALYSIS AND TRENDS...WV IMAGERY SHOWS A W-E ORIENTED S/WV
APPROACHING FROM THE SOUTH MOVING NWD ACROSS CO ALONG WITH A WAVE OF
ENERGY RIDING NWD ALONG WESTERN EDGE OF THE CONVECTION ACROSS W/CENTRAL
KS.  AS THIS S/WV CONTINUES TO LIFT NWD AXIS OF HVY RAINFALL IS EXPECTED
TO SETUP AND LIE SE-NW ACROSS NE CO/W NE THRU E WY AND INTO W SD/SE MT
AND WHERE SFC THET-E RIDGE AXIS IS SEEN STRETCHED ACROSS THIS SAME AREAS
PER 01Z SFC ANALYSIS.  RAINFALL RATES ALREADY APPEAR TO BE INCREASING
IN LAST HR..PARTICULLARY ACROSS NE CO/W NE.
.
IR ANIMATION IS SHOWING CLOUD TOPS ACROSS THE DISCUSSION AREA TO BE
COOLING IN LAST HR (NOW AROUND -55C).  COOLING AND EXPANSION OF CLOUD
TOPS ARE EXPECTED TO CONTINUE AS THE MID-LVL WAVE MOVES NWD ACROSS
CO/KS/NE IN THE NEXT FEW HRS.  THIS SHOULD PROVIDE INCREASED UVVS ACROSS
THE DISCUSSION AREA AND ULTIMATELY LEADING TO HIGHER RAINFALL RATES.
LOCALIZED AREAS ALONG THE SE SIDES OF THE BACK HILLS MAY SEE ADDITIONALLY
ENHANCED RAIN RATES WITH OROGRAPHIC EFFECTS.  RAINFALL AMOUNTS OVER NEXT
SEVERAL HRS MAY REACH UP TO 1-3" ACROSS THE DISCUSSION AREA AS RAINFALL
RATES BETWEEN 0.75-1.0"/HR ARE LIKELY.
