Weather Summary for Iowa
National Weather Service Des Moines IA
446 AM CDT Thu Jul 20 2017

A boundary draped across far northern to northeast Iowa into southern
Minnesota and southern Wisconsin early this morning. Storms were found
along and north of this boundary in southeast Minnesota and southwest
Wisconsin. South winds prevailed over central to southern Iowa,
Missouri, Nebraska and Illinois causing temperatures to remain in the
upper 70s to lower 80s in the region. Heat index values remained in
the middle to upper 80s over portions of the aforementioned region.

Hot and humid weather is expected to persist today through Saturday
over much of the region. Highs will rise well into the 90s to near 100
degrees over central and southern Iowa into Missouri, Nebraska and
Illinois with heat index values ranging from 100 to 110 F this
afternoon and again Friday. Storms are possible late tonight into
Friday across northern Iowa into Minnesota, southern Wisconsin, and
southeast South Dakota. The potential for locally heavy rain and
isolated severe storms exists in this location. Saturday will see one
final day of the hot and humid conditions before a cold front sweeps
across the region. By Sunday and into early next week, temperatures
look to be back into the 80s with much less humidity.
