EVENT...CONVECTION CONTINUING TO INCR..POTENTIAL FOR VERY SIGNIFICANT MCS
.
SATELLITE ANALYSIS AND TRENDS...TSTMS HAVE CONTINUED TO INCR ACRS THE AREA
FM CENTRAL TO NE CO..WITH CELL MERGERS TO THE N AND NE OF AFF. TSTMS HAVE
BEEN RAPIDLY SPREADING EWD..AND NEW ONES HAVE BEGUN TO FORM AS SUSPECTED
PER PREVIOUS SPENES OVER NERN CO COUNTIES..E AND NE OF AKO. OVER THE NEXT
1-2 HRS WOULD EXPECT MERGERS TO OCCUR INVOF SEDGWICK..PHILLIPS..YUMA
COUNTIES..WITH 1-2" OCCURRING IN AN HR AND SOME TOTALS IN EXCESS OF
2" PSBL.
.
NEBRASKA...SW-NE BAND OF COLD TOP CNVTN PERSISTS ACRS AREA FM SW
LINCOLN/HAYES THRU CUSTER/LOUP COUNTIES. THE MOST SIGNIFICANT CELL
TRAINING AND MERGERS HAVE TAKEN PLACE OVER LINCOLN COUNTY THROUGHOUT
THE AFTN...WHERE AUTOMATED STLT HYDROESTIMATOR INDICATES 3-4" HAS
FALLEN..ALTHOUGH THIS MAY BE ON THE LIGHT SIDE AS THE HYDROESTIMATOR
DOES NOT TAKE INTO ACCOUNT CELL MERGERS. UNFORTUNATELY..LATEST IMAGERY AT
2045Z IS SHOWING NEW CELLS DEVELOPING OVER THE FAR SWRN NEB COUNTIES..AND
ALSO OVER THE PANHANDLE COUNTIES INVOF SNY. GOES WV IMAGERY SHOWS UPPR
DIFFLUENCE BEGINNING TO INCR OVER NE CO/SW NEB.
.
STLT TRENDS PAINT A RATHER OMINOUS PICTURE REGARDING EVOLUTION OF MCS
WITH VERY HEAVY RAINFALL IN GENERAL VCNTY OF NE CO/SW NEB AREA. LATEST
OBJECTIVE ANALYSIS OF SFC DATA SHOWS STRONG BULLSEYE OF SFC CONVERGENCE
ENCOMPASSING NE CO/SW NEB/NW KS. CANNOT STRESS ENOUGH THE POTENTIAL FOR
TORRENTIAL RAINFALL AMOUNTS OVER THIS AREA THIS EVENING/TONIGHT DUE TO
CELL TRAINING AND MERGERS. WILL CONTINUE TO MONITOR AND ISSUES SPENES
UPDATES AS THE SITUATION EVOLVES.
