Weather Summary for Eastern Nebraska and Southwest Iowa
National Weather Service Omaha/Valley NE
330 PM CDT Thu May 18 2017

Persistent clouds and northeast wind led to a chillier day across
Nebraska and Iowa today.  Late afternoon temperatures ranged from
the upper 40s in northcentral Nebraska to the upper 60s extreme
southeast Nebraska and southwest Iowa.  Winds were northeast at
speeds of 10 to 15 mph.

A potent storm system will move northeast from the southern Rockies
into the central High Plains tonight. Strong to severe storms
already were ongoing across the southern Plains, and further
development is expected along a warm front across southern Kansas.
As the upper storm system moves eastward, a large area of rain with
embedded thunderstorms will move north into Nebraska and Iowa.
Isolated severe storms will be possible across southern Nebraska and
southwest Iowa. Several rounds of thunderstorms will produce
significant rainfall accumulations between tonight and Friday
evening, setting the stage for both flash flooding and river
flooding.  Storm total rainfall through early Saturday will range
from about one and one-half inches across north-central and
northeast Nebraska to three and one-half inches in southeast
Nebraska and southwest Iowa.

Lows tonight will be in the mid 40s to mid 50s.  Highs on Friday
will range from the upper 40s to the middle 60s.
