...SEVERE WEATHER OUTLOOK FOR SOUTH CENTRAL NEBRASKA AND FOR A PART
   OF NORTH CENTRAL KANSAS...

SPOTTER ACTION...SPOTTER ACTIVATION IS NOT ANTICIPATED ACROSS THE
REGION TODAY OR TONIGHT.

SYNOPSIS...

SCATTERED SHOWERS AND A FEW THUNDERSHOWERS ASSOCIATED WITH AN UPPER
LEVEL DISTURBANCE WILL CONTINUE TO MOVE SLOWLY EAST THIS AFTERNOON.
THEY WILL BE CONFINED TO AREA SOUTHEAST OF GRAND ISLAND...HASTINGS...
AND PHILLIPSBURG...AND ARE NOT EXPECTED TO BE SEVERE.

FURTHER WEST...THE ATMOSPHERE WILL BECOME INCREASINGLY UNSTABLE AS
TEMPERATURES CLIMB TO NEAR 80 AND DEWPOINTS REMAIN IN THE LOW 60S.
WIDELY SCATTERED THUNDERSTORMS MAY DEVELOP LATE THIS AFTERNOON ALONG
