SATELLITE ANALYSIS AND TRENDS...LATEST IR IMAGERY SHOWS THAT MCS THAT
ORIGINATED OVER THE FRONT RANGE HAS MOVED EAST AND IS NOW SITUATED OVER
CNTRL NE.  CLEAR CYCLONIC CIRCULATION IN LL CLOUD FIELD IS INDICATIVE
OF MCV THAT HAS FORMED AND IS CURRENTLY LOCATED OVER SW NE.  AS NOTED IN
RECENT SWOMCD THIS FEATURE APPEARS AS THOUGH IT HAS AIDED STRENGTHENING
LLJ AS LOCAL VWPS HAVE SHOWN AN INCREASE TO BETWEEN 30-40KTS OVER THE LAST
1-2HRS OVER S CNTRL NE.  225 WIND DIRECTION IS ALIGNED WELL WITH GOES
ANALYZED MOISTURE AND INSTABILITY AXIS TO ISENTROPICALLY TRANSPORT BEST
MOISTURE AND INSTABILITY INTO SE NE.  CONCURRENT WITH THE STRENGTHENING
LLJ, HAVE NOTED A FAIRLY RAPID INCREASE IN CONVECTION FROM THE VIC OF
HDE TO OMA.  MOST SIGNIFICANT CONVECTION APPEARS TO BE JUST NORTH OF
MCV CENTER FROM BUFFALO TO DAWSON COUNTY AND ALSO WITH RAPIDLY COOLING
AND MERGING CONVECTION NEAR PLATTE AND NANCE COUNTIES.  NARROW POOL
OF MOISTURE ALONG FRONTAL BOUNDARY FEATURED GOES DIGITAL PRECIPITABLE
WATER VALUES IN EXCESS OF 1.75" FROM S CNTRL NE THROUGH W CNTRL IA.
THIS COMBINED WITH THE TENDENCY FOR TRAINING CONVECTION SHOULD ALLOW
FOR LOCAL RAINFALL RATES OF 1-2"/HR SIMILAR TO WHAT OCCURRED AT MCK.
SHORTWAVE RIDGING NE OF KS UPPER LOW SHOULD ENSURE FRONTAL BOUNDARY
SHOULD BE A SLOW MOVER SO AT LEAST FOR THE SHORT TERM BELIEVE HEAVY
RAINFALL THREAT SHOULD BE MAXIMIZED ALONG AN AXIS FROM ABOUT 20 MILES
N OF HDE TOWARDS THE OMA AREA.  LOCALIZED RAINFALL AMOUNTS OF 1-3"
ARE POSSIBLE OVER THE NEXT FEW HOURS.  WILL CONTINUE TO MONITOR.
