THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHWEST
IOWA...WEST CENTRAL IOWA...EAST CENTRAL NEBRASKA...NORTHEAST
NEBRASKA AND SOUTHEAST NEBRASKA.

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON OVER THE
WESTERN HIGH PLAINS TOWARD CENTRAL NEBRASKA. SOME OF THESE STORMS
COULD MOVE TOWARD COLUMBUS...NORFOLK AND ALBION BY LATE THIS
AFTERNOON...BUT THIS IS MORE LIKELY TO OCCUR THIS EVENING. THE
STRONGER OF THESE STORMS COULD PRODUCE LARGE HAIL AND DAMAGING
WINDS.

THUNDERSTORMS...POSSIBLY SEVERE...COULD MOVE EAST ACROSS
MUCH OF THE AREA TONIGHT. THE GREATEST RISK OF SEVERE WEATHER
TONIGHT WOULD APPEAR TO BE WEST OF OMAHA AND LINCOLN...BUT A
SEVERE STORM CANNOT BE RULED OUT ANYWHERE OVER THE REGION. LARGE
HAIL AND DAMAGING WINDS WOULD APPEAR TO BE THE PRIMARY HAZARDS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

ON SUNDAY THE UPPER LEVEL SYSTEM WILL LIKELY CAUSE LOW PRESSURE TO
DEEPEN SOMEWHERE OVER EASTERN NEBRASKA DURING THE AFTERNOON. THIS
COULD SET THE STAGE FOR ANOTHER ROUND OF SEVERE WEATHER. THE MAIN
SEVERE WEATHER THREAT WILL BE VERY LARGE HAIL...GREATER THAN TWO
INCHES...AND DAMAGING WINDS. IN ADDITION...A DRY-LINE AND WARM
FRONT COULD RESIDE OR MOVE INTO THE REGION PRODUCING THE RISK FOR
TORNADO DEVELOPMENT.

THE CHANCE FOR THUNDERSTORMS CONTINUES THROUGH TUESDAY OF NEXT
WEEK.

.SPOTTER INFORMATION STATEMENT...

THERE IS A CHANCE THAT SPOTTERS COULD BE NEEDED BY LATE THIS
AFTERNOON...BUT MORE LIKELY TONIGHT AS THE SEVERE WEATHER THREAT
INCREASES.
