Weather Summary for Eastern Nebraska and Southwest Iowa
National Weather Service Omaha/Valley NE
353 AM CDT Thu Aug 17 2017

Skies started clearing out Wednesday evening across eastern Nebraska
and southwest Iowa. However a band of lower clouds was skirting parts
of northeast Nebraska and west central Iowa after midnight. By 3 AM
most reporting sites had clear skies, with temperatures in the lower
to middle 60s.

High pressure will control the weather across Mid America today,
settling into the region behind the low pressure system that brought
widespread rains to much of the area on Wednesday. However another
low pressure system is forecast to enter the High Plains of the
western Dakotas and Nebraska late this afternoon, then move into
eastern South Dakota and eastern Nebraska overnight. There is a
chance for thunderstorms with this system as it tracks east,
beginning this afternoon in western sections of South Dakota and
Nebraska, then spreading into central and eastern sections of South
Dakota, Nebraska and Kansas overnight.

Temperatures will remain mild over the eastern half of Mid America
where west to northwest winds maintain slightly cooler temperatures.
A return to southerly winds ahead of the next system will lead to
warmer temperatures to the west. Expect highs this afternoon to
range from the 70s and lower 80s in Iowa, to the lower 90s in parts
of western South Dakota through western Kansas. Overnight lows should
settle back into the 50s and 60s.
