...SEVERE WEATHER OUTLOOK FOR EASTERN NEBRASKA AND SOUTHWEST IOWA...

THERE IS A SMALL CHANCE THAT STORM SPOTTERS MAY BE NEEDED ACROSS
NORTHEASTERN NEBRASKA THIS EVENING AND TONIGHT...MAINLY TO THE NORTH
OF A LINE FROM ELGIN TO WAYNE.

THERE IS A CHANCE THAT THUNDERSTORMS WILL DEVELOP IN NORTH CENTRAL
NEBRASKA THIS EVENING OR EARLY TONIGHT...IN ADVANCE OF A COLD FRONT
WHICH WILL CROSS THROUGH THE AREA LATER TONIGHT.  IF THESE STORMS
MOVE INTO NORTHEAST NEBRASKA BEFORE MIDNIGHT...A FEW COULD PRODUCE
LARGE HAIL OR DAMAGING WIND.  STORMS ARE EXPECTED TO WEAKEN LATER
TONIGHT AS TEMPERATURES COOL AND INSTABILITY DECREASES.
