814 PM CDT Thu Jun 20 2019

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

.DAY ONE...Overnight.

There is a good chance of thunderstorms across most of the outlook
area between 11 PM and sunrise, with some storms likely to be
severe. The general expectation is for one or two larger-scale
lines or clusters of storms to sweep across the area from west-
to-east, with perhaps more isolated to scattered activity
redeveloping behind them. The main severe weather threats
overnight will be damaging wind gusts up to around 70 MPH and
large hail up to around golf ball size. Although flooding is not
expected to be a major issue, localized areas could receive a
quick 1 to 2 inches of rain, which could promote at least brief,
minor flooding.

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

A few thunderstorms may linger across portions of the outlook
area into Friday morning, but better chances will return once
again late Friday afternoon and mainly Friday night. There will
again be the potential for strong to severe storms, with large
hail, damaging winds and locally heavy rain the primary hazards.

There are additional chances for thunderstorms Saturday through
Sunday, then again Tuesday night into Wednesday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed across various portions of the
outlook area overnight.
