Weather Summary for Eastern Nebraska and Southwest Iowa
National Weather Service Omaha/Valley NE
451 AM CDT Thu Mar 15 2018

Skies were mostly clear overnight across eastern Nebraska and
southwest Iowa, with only a thin veil of high clouds streaming
overhead. There was a wide range of temperatures reported at 3 AM,
with the cool spots being Clarinda and Red Oak at 30 degrees, and the
warmest being Falls City at 51. However most locations had fallen
back into the lower and middle 30s.

The main weather-makers for Mid America through tonight will be a
strengthening low pressure system in eastern Colorado, and a warm
front extending east from the low across northern Kansas and
Missouri. These two features will remain mostly stationary through
the afternoon before drifting northeast into the Plains tonight.

North of the warm front today, easterly winds and increasing clouds
are forecast in Nebraska and Iowa, keeping temperatures a bit cooler
than we saw on Wednesday. South of the warm front, southerly winds
should help Kansas and Missouri warm up a bit more than Wednesday. As
the low pushes into Mid America overnight, a band of rain and
possible thunderstorms will develop in western and central Nebraska
into Kansas. That area is expected to spread east into Iowa and
Missouri by Friday morning. Meanwhile colder air spilling south could
change some of the rain to freezing rain or sleet in parts of
South Dakota and northern Nebraska.

Expect afternoon highs to range from the 50s from northern Nebraska
through Iowa, to the 70s in Kansas and much of Missouri. Lows tonight
will drop back into the 20s from South Dakota through northern Iowa,
while holding in the 40s or lower 50s in Kansas and Missouri.
