SATELLITE ANALYSIS AND TRENDS...CONVETION CONTINUES TO ADVANCE EWD OVER
NE CO..WITH NUMEROUS CELL MERGERS TAKING PLACE OVER PHILLIPS AND YUMA
COUNTIES ACCOMPANIED BY VERY HVY DOWNPOURS. AT THE SAME TIME..TSTMS OVER
SW NEB HAVE CONTINUED TO BACKBUILD AND NOW EXTEND INTO DUNDY COUNTY. ON
IR AND VIS IMAGERY..NUMEROUS OVERSHOOTING AND COOLING TOPS ARE OVER
HITCHCOCK/HAYES/LINCOLN COUNTIES. CLOUD TOP TEMPS HAVE COOLED TO -68C..AND
WOULD EXPECT TOPS TO COOL FURTHER INTO THE -70SC. WITH THE LATEST TREND
OVER THE SWRN NEB COUNTIES..AND WITH THE ANTICIPATED MERGER FROM THE CO
STMS..WOULD EXPECT NUMEROUS SPOTS WILL RECEIVE RAINFALL AMOUNTS BTWN
2-3" IN AN HOUR..AND ADDITIONAL RAINFALL TOTALS OF AT LEAST 3-5" FOR
SOME LOCATIONS. COUNTIES SUCH AS DUNDY/HITCHCODK/HAYES/LINCOLN/FRONTIER
WILL BE ESPECIALLY HARD HIT. UNFORTUNATELY..THESE COUNTIES HAVE ALREADY
EXPERIENCED VERY HVY RAINFALL ALREADY FROM LAST NIGHTS EVENT AS WELL AS
TODAYS. VIS IMAGERY CONTINUES TO SHOW CU SURGING NWD FM KS INTO THE AREA
AS WELL. LATEST OBJECTIVE ANALYSIS SHOWS CONVERGENCE BULLSEYE CENTERED
OVER NW KS AND EXTENDING INTO E CO AND SW NEB. THIS..IN CONJUNCTION WITH
STLT TRENDS..ALSO INDICATES THAT VERY HVY RAINFALL WILL SPREAD ACRS NW KS.
