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 should gradually decrease in coverage through the
mid morning hours. A flash flood watch continues for Richardson,
Nemaha and Pawnee counties.

Additional thunderstorms will be possible this afternoon, but
these should mostly stay below severe limits. There will be an
increasing chance of thunderstorms this evening and into tonight.
Some storms could be severe, with large hail and damaging winds,
mainly between about 8 pm and 3 am. Locally heavy rain could also
occur. The chance of severe storms is highest just to the north
of our area, across South Dakota and northwest Iowa.

Minor flooding will continue on the Missouri River above Lewis
and Clark Lake and from around Plattsmouth downstream past Rulo.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

There is a small chance of thunderstorms during the daytime hours
of Sunday, but these are not expected to be severe.

Hot and humid conditions are forecast for Monday afternoon and
Tuesday afternoon. Heat index values could reach around 100 to 105
across parts of southeast Nebraska and southwest Iowa.

There will be a chance for thunderstorms for at least portions of
the area from late Monday night through the mid part of the week.
Later outlooks will address the potential for severe storms in
those periods.

Minor flooding should continue on the Missouri River above Lewis
and Clark Lake and from around Plattsmouth downstream into
Missouri.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected to be needed, but please pass
along any reports of severe weather or flooding.
