This Hazardous Weather Outlook is for portions of western and
north central Nebraska.

.DAY ONE...TODAY AND TONIGHT.

The thunderstorms that moved northeast overnight added to an
already saturated ground for increased runoff across much of
northern Nebraska into areas generally north of Highway 92.
Ponding of water on portions of Highway 92 and Highway 97,
between Tryon and Arthur and south of the Merritt Reservoir
respectively, caused road closures per the Nebraska 511 web page.

Tonight the chance for thunderstorms return over southwest
Nebraska where runoff may lead to increased overland flooding.
High flows continue on portions of the Keya Paha River, Plum
Creek and the Elkhorn River. You can refer to the latest flood
warnings and advisories for additional details.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.

Additional rainfall through Tuesday will increase the threat for
flooding as high water tables increase runoff capability across
western and north central Nebraska. Localized heavy rainfall
increase Sunday night and will continue through Tuesday as
thunderstorms remain in the forecast.

The chance for severe thunderstorms return Sunday afternoon and
evening. The area of concern is generally along and south of
Highway 2 with large hail and damaging winds possible.

Yet, thunderstorms are forecasted for Saturday night, Monday and
Tuesday. The risk of severe weather on these days are low at this
time.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed through tonight.
