Weather Summary for Eastern Nebraska and Southwest Iowa
National Weather Service Omaha/Valley NE
301 PM CDT Tue Sep 12 2017

Lots of sunshine and light winds allowed temperatures to climb into
the lower and middle 80s as of 3 PM across eastern Nebraska and
southwest Iowa. The only clouds seen were thin high clouds spreading
northwest from the remnants of Hurricane Irma spinning in the
southeast U.S. Our winds were also being affected by Irma, as east
to northeast flow was noted across southwest Iowa and southeast
Nebraska on the outer fringes of the larger circulation. Otherwise
winds were from the south and southeast from I-80 and north.

The low pressure system left behind by Irma is forecast to lift
north from Alabama into the Ohio Valley region by Wednesday
afternoon. Meanwhile, low pressure is expected to deepen in the High
Plains of western South Dakota and Nebraska. In between, much of
Mid America will see an increase in southerly winds and not a lot of
cloud cover. A slight increase in humidity will be felt in some part
of the region, helping to fuel scattered showers and thunderstorms
Tuesday evening from central South Dakota into central Nebraska.
Then a few afternoon thunderstorms could form in western South
Dakota and the Nebraska Panhandle on Wednesday.

Otherwise another mild night is forecast as temperatures drop into
the 50s and lower 60s. Then a warm day can be expected Wednesday,
with highs ranging from the middle 80s in Iowa and Missouri, to the
middle and upper 90s in western parts of South Dakota, Nebraska and
