Weather Summary for Eastern Nebraska and Southwest Iowa
National Weather Service Omaha/Valley NE
459 AM CDT Tue Sep 19 2017

Clouds began to increase just after midnight across eastern Nebraska
and southwest Iowa, with mostly cloudy skies noted over much of the
area. A persistent southeast wind of 10 to 15 mph helped to keep fog
from dropping visibilities too far, as most sites were reporting
visibilities between 3 and 5 miles. The exception was near Albion
where quarter mile visibilities were seen. Temperatures at 4 AM were
generally in the middle 60s, with Norfolk the coolest at 62 degrees
and Omaha the warmest at 68.

Strong south winds are forecast to develop across Mid America today
as a low pressure system deepens in the Dakotas into western
Nebraska. That low pressure will move east overnight, driving a cold
front east from the western Dakotas into Iowa and eastern Kansas by
Wednesday morning. Scattered thunderstorms are possible along the
front, focusing on western and central South Dakota during the day,
then eastern South Dakota, northeast Nebraska and parts of Iowa

Cooler temperatures will follow the front as well, but not before a
very warm and humid afternoon. Under mostly sunny skies, expect high
temperatures to reach the 80s over most of the region, with parts of
Kansas and southern Nebraska seeing highs in the 90s. Lows tonight
are forecast to range from the 40s in western South Dakota and
western Nebraska, to the 70s ahead of the front in Missouri and
eastern Kansas.
