SATELLITE ANALYSIS AND TRENDS...IR/VIS TRENDS HAS SHOWN AN ISOLATED
THUNDERSTORM OVER CENTRAL ND ALONG THE SOUTHERN EDGE OF DEFINED N-S
BOUNDARY IN MCLEAN COUNTY.  TOPS HAVE REMAINED WARM AROUND -50C WITH
GOOD SFC MOISTURE (TD IN IN THE MID TO UPPER 50S) AND PWS OF .9" WHICH
NORMALLY WOULD NOT LEAD TO HIGH SATELLITE ESTIMATION FOR RATES...BUT DUE
TO THE 2.5 HR STATIONARY NATURE OF THE CELL...PROFILE IS WELL MOISTENED
FOR EFFICIENT RAINFALL TOTALS.  RATES OF 1.0"/HR WITH THE ADDITION OF .5"
FOR STATIONARY... HAVE LEAD TO MANUAL ESTIMATION OF 2.5" TOTAL OVER THE
AREA...WHICH EXCEEDS 3HR FFG VALUES IN THE AREA

RECENT VIS IMAGERY SHOWS LOCAL DISRUPTION OF THE STATIONARY CELL AS NEW
TOWERS ARE BUILDING AROUND THE STORM... THIS ALONG WITH NEW CU FIELD
RAPIDLY DEVELOPING INTO A LINE OF THUNDERSTORMS ACROSS W ND COULD LEAD TO
A LARGER COMPLEX EARLY THIS EVENING OVER THIS SAME AREA. STILL THE N-S
BOUNDARY CAN STILL BE SEEN THOUGH OUTFLOW IS BREAKING THE LINE ACROSS
C ND...IT IS THE STATIONARY NATURE OF THIS BOUNDARY THAT MAY LEAD TO
SIMILAR STATIONARY STORMS ALONG IT WITH INCREASED THREATS OF  MERGERS
THAT CAN LEAD TO ADDITIONAL LOCALIZED FF THREATS.
