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

.DAY ONE...This Afternoon and Tonight.

This evening and overnight, although the majority of the outlook
area should remain thunderstorm-free, there is a chance that a few
storms could develop mainly within Nebraska counties north of
Interstate 80. Most activity should not be severe, but there is a
slight chance of isolated severe storms along and north of
Highway 92. If a severe storm manages to develop in that area,
hail to near the size of quarters and wind gusts to around 60 mph
will be the main threats.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.

Between Sunday and Friday, there are several, on-and-off chances
for thunderstorms within the area, as we remain in an active
weather pattern. That being said, it will be difficult to predict
specific day-to-day thunderstorm chances with much confidence,
especially more than a day or two in advance, so please note that
many of these chances could fluctuate upward or downward
noticeably as they get closer in time.

It will also be difficult to confidently assess the potential for
severe thunderstorms more than a day or two in advance. However,
the next chance for severe storms will be late Sunday afternoon
and evening, and some of this activity may last into the overnight
hours. Although details will still be fine-tuned through tomorrow,
areas of central and eastern Nebraska will see isolated to
scattered thunderstorms, some of which will probably be severe.
These will have the potential to produce hail to near the size of
golf balls and/or damaging winds. The most likely timeframe for
storms Sunday will be from approximately 5 PM to 1 AM. As a
result, the entire outlook area is currently under at least a
Marginal Risk of severe storms, and eastern portions of the
outlook area are under a Slight Risk for severe storms, for this
time frame.

.SPOTTER INFORMATION STATEMENT...

Spotter activation should not be needed through tonight, but any
reports of severe weather or storm damage from previous activity
over the last 24 hours would be greatly appreciated.
