.
SATELLITE ANALYSIS AND TRENDS...SATELLITE IMAGERY SHOWED A VERY RAPIDLY
DEVELOPING CELL OVER NRN CHERRY COUNTY BETWEEN 0015Z AND 0115Z WHERE
TOPS COOLED TO -68C/-70C.  ESTIMATING THAT UP TO 2.0” FELL IN SOME
LOCATIONS DURING THAT TIME FRAME.

VIS IMAGERY SHOWING OVERSHOOTING TOP OVER S SHERIDAN COUNTY IN NW NE WITH
CLOUD TOP TEMPS AROUND -70C DEVELOPED AFTER A MERGER IN THE WRN PORTION
OF THE COUNTY NEAR THE BOX BUTTE COUNTY BORDER.  WHILE CELL LOOKS TO BE
MOVING..STILL EXPECTING THAT SOME AREAS MIGHT HAVE SEEN 1.5”-2.0”
IN 30 MIN UNDER THE MERGER.

VIS IMAGERY SHOWING SOME OVERSHOOTING TOPS MOVING SWD TOWARDS
CONVECTION..AS WELL AS AN OVERSHOOTING TOP ON THE LEADING EDGE OF THE
CONVECTION TO THE W OVER SHERIDAN COUNTY.  WHILE CELLS ARE STILL FAR
FROM EACH OTHER..STILL WOULD NOT COUNT OUT A MERGER BETWEEN THEM WHICH
COULD PUSH RAIN RATES UP TO 1.5”-2.0”/ 30 MIN FOR A PERIOD OF TIME
UNDER THE MERGER WITH PW VALUES AROUND 1.3” PER SOUNDS/GPS DATA.

CHECK WEB IN APPROX 10 MIN FOR MESSAGE GRAPHIC.
