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

.DAY ONE...This Evening and Tonight.

At least isolated thunderstorm activity is possible almost
anywhere in the outlook area through tonight, but widespread
coverage is not anticipated. Severe storms are not expected,
but a few could be strong enough to produce small hail and gusty
winds, particularly within some counties south of Interstate 80
into this evening.

Due to heavy rain that fell Wednesday morning, flooding continues
along the West Fork Big Blue River in southern Hamilton, southern
York and far northern Fillmore counties. Please refer to the
latest Flood Warning statement for further details.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.

A Flood Warning remains in effect through Friday afternoon for
the West Fork Big Blue River in southern Hamilton, southern York
and far northern Fillmore counties. Please refer to the latest
Flood Warning statement for further details.

Throughout much of this six-day period, there are a number of
chances for at least spotty thunderstorm activity within various
parts of the outlook area. Please note that this is a very
tricky-to-forecast summer weather pattern, so many of these
thunderstorm chances are subject to change as they get closer.
That being said, most of the highest chances for potentially more
widespread activity should concentrate between Friday night and
Monday, with an overall-drier weather pattern expected to settle
in beyond that.

.SPOTTER INFORMATION STATEMENT...

Spotter activation should not be needed through tonight, but any
reports of possible hail or gusty winds would be appreciated.
