SEVERE WEATHER OUTLOOK FOR WESTERN AND NORTH CENTRAL NEBRASKA
NATIONAL WEATHER SERVICE NORTH PLATTE NE
1130 AM CDT (1030 AM MDT) THU AUG 15 1996

THIS OUTLOOK PERTAINS TO THE FOLLOWING NEBRASKA COUNTIES...

ARTHUR     BLAINE     BOYD       BROWN      CHASE      CHERRY
CUSTER     DEUEL      FRONTIER   GARDEN     GARFIELD   GRANT
HAYES      HOLT       HOOKER     KEITH      KEYA PAHA  LINCOLN
LOGAN      LOUP       MCPHERSON  PERKINS    ROCK       SHERIDAN
THOMAS     WHEELER

...STORM SPOTTER ACTIVATION MAY BE REQUIRED OVER WESTERN AND
PARTS OF NORTH CENTRAL NEBRASKA TODAY AND TONIGHT...

THERE IS A SLIGHT CHANCE FOR SEVERE THUNDERSTORMS TO DEVELOP TODAY AND
TONIGHT OVER THE OUTLOOK AREA. THE GREATEST RISK OF SEVERE THUNDERSTORM
DEVELOPMENT WILL BE WEST OF A LINE FROM VALENTINE TO BROKEN BOW.
A SLOW MOVING FRONT IN WESTERN NEBRASKA WILL HELP TO FOCUS ABUNDANT
MOISTURE TO PRODUCE SCATTERED THUNDERSTORMS TODAY AND TONIGHT. WITH
AFTERNOON HEATING THE ATMOSPHERE WILL BECOME MORE UNSTABLE CAUSING
THUNDERSTORMS TO APPROACH SEVERE LIMITS. UPPER LEVEL DISTURBANCES
MOVING SOUTHEAST ACROSS THE OUTLOOK AREA WILL HELP TO INTENSIFY THE
THUND4ERSTORMS SO THAT A FEW OF THESE STORMS WILL BECOME SEVERE ACROSS
WESTERN NEBRASKA AND PARTS OF NORTHCENTRAL NEBRASKA.
