Weather Summary for Eastern Nebraska and Southwest Iowa
National Weather Service Omaha/Valley NE
345 AM CDT Thu Jun 22 2017

Skies were partly to mostly clear overnight across eastern Nebraska
and southwest Iowa. A few thunderstorms tried to get going between
midnight and 2 AM in parts of northeast Nebraska from near Hartington
and Coleridge down to Albion and Columbus. However those storms had
dissipated rather quickly. Other thunderstorms in south central
Nebraska were skirting the southwest corner of Jefferson county to
the southwest of Fairbury as of 3 AM. Temperatures overnight remained
quite mild with 3 o`clock readings mainly between 75 and 80 degrees.
South winds were averaging 5 to 15 mph overnight.

A cold front is forecast to drift southeast from Minnesota and South
Dakota into Iowa and Nebraska this afternoon, then into southern
Kansas and Missouri overnight. Most of any potential thunderstorm
activity is expected along and behind this front. Strong
thunderstorms this morning in northern South Dakota should move off
into Minnesota by noon or so. Then more development along the cold
front is forecast this afternoon from southern Minnesota into eastern
and central Nebraska, and into western Kansas. A few of those storms
could produce hail and damaging winds.

Overnight, a gradual southward shift to the thunderstorms is expected
as the cold front sinks farther south. Much of Nebraska and Iowa will
see storms ending after midnight, but most of Kansas and Missouri
should see thunderstorms all night long.

Behind the cold front, cooler temperatures are forecast as highs in
South Dakota and northern sections of Nebraska and Iowa only reach
near 80 degrees for afternoon highs. South of the front, much warmer
90s are forecast from Kansas through southern Nebraska and southwest
Iowa. Lows tonight will fall back into the 50s over most of South
Dakota, northern Iowa, and northern and western Nebraska. Farther
south, lows in the 60s are expected in Kansas, Missouri, southern
Iowa and southeast Nebraska.
