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

.DAY ONE...Tonight and Friday

Severe thunderstorms are likely into the evening as a strong
storm system moves through the region. Most of the severe storms
will occur south of a warm front extending through southeast
Nebraska and southwest Iowa, generally south of a line from
Saline to Plattsmouth and Oakland Iowa. Large hail, damaging
winds, and isolated tornadoes are possible in these areas. Large
hail could occur north of this area, generally from Lincoln to the
Omaha Metro and to Harlan Iowa. The storms are forecast to move
east of our area by mid evening.

Also, a winter weather advisory is in effect through tonight for
northeast Nebraska. Rain will change to snow this evening, with
total snow amounts in the 1 to 4 inch range, especially north of
a line from Albion to West Point and Onawa. Along with the snow,
north winds gusting over 40 mph will cause blowing snow, severely
reducing visibilities.

The rain and snow is expected to be east of our area by sunrise
Friday.

.DAYS TWO THROUGH SEVEN...Friday night through Thursday

There is a small chance of snow for parts of the area Saturday
night into Sunday morning. A few thunderstorms will be possible
from Monday night through Tuesday.

.SPOTTER INFORMATION STATEMENT...

Spotters are encouraged to call in any severe weather reports
through this evening. There is a chance storm spotter activation
may be needed.
