Weather Summary for Eastern Nebraska and Southwest Iowa
National Weather Service Omaha/Valley NE
1139 AM CDT WED JUL 20 2016

Isolated thunderstorms will be possible over parts of the Midwest
the rest of today, then a chance the rest of the workweek.  However,
the main feature will be excessive Heat, heat that will start to
build across the Plains states through today, and then persist into
Friday and possibly Saturday. The hot and humid weather is in
response to a strong ridge of high pressure building in the mid and
upper levels of the atmosphere over the central United States.  This
ridge will start to move south as the weekend approaches, with
slightly cooler conditions from Nebraska and Iowa northward.  On
Saturday, while a cold front is expected to advance through the
area, hot temperatures will still be found ahead of that front,
especially across Kansas and Missouri.

High temperatures this afternoon, mid 90s to 105 across the Northern
and Central plains, and 85 to the mid 90s across the upper and
middle Mississippi Valley region.  Heat index values for the plains
region through Friday 102 to 113 degrees. Low temperatures tonight
mostly in the 70s, save for values in the 60s across western North
Dakota into northwest Kansas. For eastern Nebraska and western Iowa,
highs mid to upper 90s, and lows mid to upper 70s.
