Weather Summary for Eastern Nebraska and Southwest Iowa

353 AM CDT Tue Oct 25 2016
Extensive cloud cover overspread eastern Nebraska and southwest Iowa
overnight as a low pressure system began to push toward the area.
Southeast winds of 5 to 10 mph along with the clouds helped to hold
temperatures from falling off too much. Readings at 4 AM were
generally in the upper 40s and lower 50s.
A low pressure system moving out of the Rockies early today will
strengthen as it moves into eastern Nebraska this evening. An
increase in humidity is expected as south winds ahead of the low
pump Gulf moisture into Mid America. The combination of these
features will lead to increasing chances for showers and
thunderstorms during the day across a good part of the Plains. While
a few showers could develop early in the day from eastern Kansas
through eastern Nebraska and western Iowa, more widespread activity
is forecast to develop in the afternoon in eastern South Dakota into
northern Iowa. An expansion of this precipitation to the southwest
is likely later today, to include eastern Nebraska and most of Iowa.
During the evening, widespread showers and thunderstorms are
forecast across eastern South Dakota, all of Iowa, and into eastern
Nebraska, eastern Kansas and northwest Missouri. Some strong
thunderstorms could occur during the evening. By sunrise Wednesday,
most of the activity will extend from eastern and central Iowa,
through northern Missouri and into eastern Kansas.
With the increasing chances for precipitation, cloud cover will also
increase across most of Mid America today. Afternoon highs are
expected to range from the 50s in northern Iowa where clouds and
precipitation will be most widespread, to the 70s and lower 80s in
Kansas where south winds and peaks at sunshine will be observed.
Clouds will begin to decrease from west to east overnight, allowing
temperatures to drop into the 40s from South Dakota through western
Nebraska, while holding in the lower 60s in Missouri and eastern
