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

There is a chance of thunderstorms over northeast  Nebraska into
parts of west central Iowa this morning. These storms should
generally be elevated, however can produce hail and gusty winds.

Severe thunderstorms will be possible later this afternoon across
northeast Nebraska, however other storms could develop away from
the front in southeast Nebraska and southwest Iowa. All modes of
severe weather are possible including large hail, damaging winds,
isolated tornadoes and locally heavy rain. The isolated tornado
risk appears to be higher in northeast Nebraska.

A warm front will lift north this morning combined with an upper
level weather disturbance...with elevated thunderstorms from South
Dakota dropping southeast across parts of northeast Nebraska into
Iowa. This afternoon...hot air will build into the region ahead of
a cold front. Unstable air will be in place with moisture pooled
along the front. It is uncertain how far south the storms will
continue to push southward into the hot air as the weather
disturbance shifts eastward.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

Severe thunderstorms are again possible Thursday afternoon and
Thursday night with the storms developing along the stalled
frontal boundary. Large hail and damaging winds along with locally
heavy rainfall are the primary hazards.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed late this afternoon and this
evening.
