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

.DAY ONE...THIS AFTERNOON AND TONIGHT

SEVERE THUNDERSTORMS WILL BE POSSIBLE TONIGHT. LARGE HAIL AND
DAMAGING WINDS ALONG WITH LOCALLY HEAVY RAIN WILL BE THE PRIMARY
HAZARDS.

ALTHOUGH AN ISOLATED SHOWER OR THUNDERSTORM MAY TRY TO GET GOING
THIS AFTERNOON DUE TO SOME ELEVATED INSTABILITY AND UPPER LEVEL
SUPPORT...THE MAIN AREA OF THUNDERSTORMS IS EXPECTED TO DEVELOP
OVER THE WESTERN HIGH PLAINS...WESTERN AND WEST CENTRAL NEBRASKA
AND WESTERN KANSAS THIS AFTERNOON. SOME OF THESE STORMS COULD MOVE
TOWARD COLUMBUS...NORFOLK AND ALBION THIS EVENING. MEANWHILE...A
STRONG LOW LEVEL JET IS FORECAST TO DEVELOP OVER EASTERN KANSAS
THIS EVENING...WITH STORMS DEVELOPING ACROSS PARTS OF EASTERN
NEBRASKA AND WESTERN IOWA OVERNIGHT. A WARM FRONT DOES TRY TO
LIFT INTO SOUTHEAST NEBRASKA AND SOUTHWEST IOWA LATE THIS EVENING
AND DOES PROVIDE SOME FAVORABLE LOW LEVEL SHEAR...HOWEVER
INSTABILITY WILL NOT BE AS FAVORABLE AT THIS TIME.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

SEVERE THUNDERSTORMS ARE AGAIN POSSIBLE SUNDAY. LARGE HAIL AND
DAMAGING WINDS WILL AGAIN BE THE PRIMARY HAZARDS.

DEPENDING ON HOW THINGS PLAY OUT TONIGHT...THERE SHOULD BE
ONGOING CONVECTION SUNDAY MORNING. AN UPPER LEVEL STORM SYSTEM
WILL CAUSE LOW PRESSURE TO DEVELOP OVER EASTERN NEBRASKA AND THESE
FEATURES WILL HELP DETERMINE WHERE THE SEVERE STORMS WILL FOCUS.
MODERATE INSTABILITY AND DEEP LAYER SHEAR ARE EXPECTED AND HIGHEST
VALUES APPEAR TO RUN FROM DAVID CITY TO TEKAMAH AND SHIFT
SOUTHEAST DURING THE DAY.

THE CHANCE FOR THUNDERSTORMS CONTINUES THROUGH TUESDAY OF NEXT
WEEK.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS MAY BE NEEDED TONIGHT AND SUNDAY.
