SATELLITE ANALYSIS AND TRENDS...PW VALUES CONTINUE TO INCREASE ALONG THE
BOUNDARY WITH CURRENT MAX NUMBERS TO 2.10" IN N.W. IOWA ALONG THE E-W
LINE MOISTER CONVERGENCE MAX.  THE LINE FROM CHEROKEE, THRU BUENA VISTA,
TO POCAHONTAS COUNTIES APPEARS TO BE THE WORST AS CONVECTION BUILDS AND
TRAINS TO THE EAST WITH ONLY SLOW SOUTHWARD DRIFT.  ESTIMATED MAX RAIN
RATES ARE UP TO ALMOST 2.5" PER HALF-HOUR, THOUGH THIS MAY BE SKEWED
A BIT HIGH DUE TO THE SEVERE SIGNATURE IN IR IMAGERY.  BACK IN CENTRAL
NEBRASKA, THE LINE APPEARS TO BE SLIGHTLY MORE PROGRESSIVE AS IT DEVELOPS,
BUT THE LINE ALONG THE GARFIELD AND VALLEY COUNTY BORDER, AND TO THE EAST,
SHOWS MAX ESTIMATED RAIN RATES TO ABOUT 1.5" PER HALF-HOUR.  THERE ARE
ALSO STRONG SEVERE WEATHER SIGNATURES ALONG THIS LINE.  THE ESTIMATED
RAIN RATE MAY NOT REACH TRUE 3-HR FFG VALUES BUT COULD BREACH LOCALIZED
FLASH FLOODING CRITERIA.
