UPGLIDE OVER A WEAK FRONT IS EXPECTED TO PRODUCE AT LEAST ISOLATED
SHOWERS AND POSSIBLY SOME EMBEDDED THUNDERSTORMS IN NORTH CENTRAL
NEBRASKA SUNDAY AFTERNOON. THEN THE FRONT COMES SOUTH THROUGH
NEBRASKA...CREATING A CHANCE OF PRECIPITATION SUNDAY EVENING AND
OVERNIGHT. THERE ARE SOME HINTS AT SOME INSTABILITY...SO IT IS
POSSIBLE THAT EMBEDDED THUNDERSTORMS COULD CONTINUE THROUGH THE
NIGHT.

A BOUNDARY DEVELOPING ON THE HIGH PLAINS WILL HELP TO GENERATE
SHOWERS AND THUNDERSTORMS AGAIN BEGINNING AS EARLY AS WEDNESDAY
AFTERNOON IN CENTRAL NEBRASKA WHERE THE FAVORABLE INSTABILITY IS AND
INCREASING IN COVERAGE TOWARD NEXT WEEKEND. WITH CONVECTIVE
POTENTIAL EXCEEDING 2500J/KG AND 0-6KM SHEAR...STRONG THUNDERSTORMS
ARE POSSIBLE THURSDAY EVENING. HOWEVER...THE MOST FAVORABLE MOISTURE
WILL ACTUALLY BE IN CENTRAL AND NORTH CENTRAL NEBRASKA WHERE THE
CONVECTIVE POTENTIAL IS NOT AS STRONG.
