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

.DAY ONE...TONIGHT AND WEDNESDAY

Severe storms are expected to move into northeast Nebraska tonight
between 9 and 11 pm, then expand east and southeast through the
remainder of the evening and overnight hours. Severe storm chances
increase in the Lincoln, Omaha and Council Bluffs metro areas by
11 to 1 am. Storms reach extreme southeast Nebraska and extreme
southwest Iowa generally after 1 am. Damaging winds of 60 to 80
mph will be the main hazard. Large hail may also occur in some of
the storms, especially in eastern Nebraska. An isolated tornado is
also possible. Locally heavy rainfall will also occur tonight,
but widespread flash flooding is not expected.

The Storm Prediction center has placed portions of eastern Nebraska
along and north of Interstate 80 in an enhanced risk of severe
storms later tonight, with a slight risk for areas east and south.
Severe weather watches and eventual warnings seem likely by late
this evening and overnight. Please make plans accordingly.

.DAYS TWO THROUGH SEVEN...WEDNESDAY NIGHT THROUGH TUESDAY

Additional severe thunderstorms will be possible Wednesday and
Thursday, along a boundary which is expected to eventually stall
extending very close to the Nebraska and Kansas border into
southern Iowa. Large hail and damaging winds will again be the
main threat with storms both Wednesday and Thursday. Locally heavy
rain will also be possible both days. If storms develop over the
same areas each day, a flooding threat may eventually develop.

Another round of thunderstorms is expected Sunday night into
Monday. At this time it is too soon to determine the severity
threat with these storms. The threat of storms appears to
exit the area by Monday night.

At this time, the July 4th holiday appears generally dry and
seasonable at this time.

.SPOTTER INFORMATION STATEMENT...

Storm spotter activation may be needed later tonight.
