SW IA
.
SATELLITE ANALYSIS AND TRENDS...CURRENT SITUATION UNFOLDING PRETTY MUCH
AS ADVERTISED IN MOST RECENT SPENES AS CAP HAS BROKEN FROM AREAS OF SOUTH
CNTRL KS INTO SW IA.  WITH THIS HAVE SEEN RAPID CONVECTIVE DEVELOPMENT
AND SUBSEQUENT DOWNSTREAM TRAINING FROM THE VIC OF P28 NE TOWARDS SDA
IN SW IA.  CELL NOW ENTERING MARSHALL COUNTY WAS EARLIER EXHIBITING A
RATHER WELL DEFINED ENHANCED-V.  THIS FEATURE HAS SINCE WEAKENED BUT NEW
CELL ACTIVITY HAS REDEVELOPED SW OF THIS FEATURE NEAR MHK.  THERE IS A
SLIGHT BREAK IN THE LINE OVER CNTRL KS BUT THEN ACTIVITY PICKS UP AGAIN
OVER S SALINE COUNTY AND EXTENDS SW TO WHAT APPEARS ANOTHER ORGANIZING
ENHANCED-V SIGNATURE OVER SW RENO COUNTY.
.
LATEST OBJECTIVE ANALYSIS SHOWS THAT SURFACE MOISTURE CONVERGENCE MAX
IS LYING UPSTREAM OF ONGOING CONVECTION AND BELIEVE THAT THIS WILL
HELP TO FURTHER REDUCE CINH FROM P28 TO GAG.  ALREADY SEEING SIGNS
OF THIS WITH RAPID COOLING CONVECTIVE TOP JUST WEST OF P28 AND ALSO
EXPERIMENTAL CONVECTIVE INITIATION ALGORITHM SHOWING SEVERAL PIXELS WITH
A HIGH LIKELIHOOD OF CONVECTIVE INITIATION OVER THE NEXT 30-45 MINUTES
BETWEEN GAG AND P28.  GOES SOUNDER PRECIPITABLE WATERS OF AROUND 1.50"
POOLED ALONG EXISTENT BOUNDARIES SHOULD HELP TO SUPPORT LOCAL RAINFALL
RATES OF 1-2"/HR IN THE MOST INTENSE CORES WITH LOCAL TOTALS OF 1-3"
POSSIBLE OVER THE NEXT 3 HRS.  WILL CONTINUE TO MONITOR SITUATION AND
UPDATE AS WARRANTED.
