Weather Summary for Eastern Nebraska and Southwest Iowa
National Weather Service Omaha/Valley NE
1100 PM CDT Mon Aug 21 2017

A band of scattered showers and thunderstorms developed over
northeast Nebraska late in the afternoon and progressed south during
the evening. By 10 PM, most of the showers and storms covered almost
all of southwest Iowa as well as eastern Nebraska south of a Columbus
to Tekamah line. Some moderate rainfall and wind gusts over 40 mph
were observed with these storms. Temperatures at 10 o`clock had
fallen in the middle and upper 60s, but remain in the lower to middle
70s in southeast Nebraska and a few spots in southwest Iowa.

A cold front dropping south through Mid America tonight will continue
to touch off showers and thunderstorms from eastern Nebraska across
Iowa, eastern Kansas and much of Missouri. Some strong to severe
storms are possible in Kansas and Missouri, with heavy rainfall also
likely. By sunrise Tuesday, the cold front will have pushed into
eastern Kansas and central Missouri, taking the rain with it out of
Nebraska and Iowa. Then by late Tuesday afternoon, the front will
lie across southern Missouri where continued thunderstorm activity is

Cooler high pressure settling in behind the cold front should result
in clearing skies from north to south tonight and Tuesday. Lows
tonight are forecast to drop into the 50s across South Dakota and
into western Nebraska, with 60s expected to the south. Under mainly
sunny skies Tuesday afternoon, expect high temperatures to range from
the middle 70s in northern Iowa to the middle 80s in western Kansas.
