This Hazardous Weather Outlook is for portions of southwest
Iowa...west central Iowa...east central Nebraska...northeast
Nebraska and southeast Nebraska.

.DAY ONE...This Afternoon and Tonight

An intense weather system will move through the area today into
Saturday. Southerly winds with gusts of 30 to 45 mph today will
switch to northwest at 45 to 60 mph late tonight into Saturday.
Travel may be difficult for light weight and high profile
vehicles.

There is a 30-50 percent chance for severe storms this afternoon
mainly between 3 and 7 PM. The main threat with the severe storms
will be damaging winds with the potential for gusts up to 75 mph,
and hail up to one inch in diameter. An isolated weak tornado
could also occur. Severe storms should initially develop along the
Kansas and Nebraska border and then shift northward through the
afternoon into the early evening. If severe storms, develop,
threat should only last about 15 minutes at any given location.

Extreme fire danger is expected for portions of southeast Nebraska
and southwest Iowa on Friday as strong winds combine with low
relative humidity. If storms don't drop much rainfall, we could see
lightning spark wildfires this afternoon and evening.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Rain will switch over to snow early Saturday morning, with up to
an inch of snow expected in northeast Nebraska by noon Saturday.
Regardless of snowfall amounts, any snow combined with the strong
winds will lead to very poor visibility with blowing snow and
potential travel impacts.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed this afternoon, and any reports
of severe weather will be appreciated.
