Weather Summary for Iowa
National Weather Service Des Moines IA
503 AM CDT Tue Jul 25 2017

High pressure moved east of the state overnight with southeast winds
increasing across Iowa. These winds helped temperatures remain
somewhat warmer than last night`s readings as temperatures held mainly
in the 60s statewide. A few high clouds moved over the state, mainly
in the north associated with storms across Minnesota.

A much warmer and more humid airmass will spread across the region
today as south winds increase ahead of an approaching cold front.
Highs will climb back into the 90s in the Missouri River valley with
80s farther north and east. Heat index values will approach 100 in
portions of western Iowa and locations to the west and south by this
afternoon under mostly sunny skies. By late afternoon into the
evening, showers and thunderstorms are forecast to develop along a
cold front from the Nebraska panhandle into western Minnesota. These
storms will produce some severe weather along with localized heavy
rainfall. This system will drop southeast into Wednesday with Iowa
seeing the best chance of strong to severe storms along with a few
locations of heavier rainfall. The system is expected to pass by
Thursday with cooler and drier weather for much of the upper Midwest
by the end of the work week.
