Weather Summary for Iowa

After a few scattered showers and storms across northeast Iowa
early today, the main story became the oppressive heat that began
to move into the state. To start, morning lows were on the mild to
warm side with low to mid 70s in western Iowa and mostly mid to
upper 60s through central and eastern Iowa. Temperatures in the
afternoon had little issue soaring into the low to mid 90s across
the southwest two thirds of the state. Coupled with dew points
approaching 80, heat index values eclipsed 110 degrees in the Des
Moines and Ames areas, while many other locations reached into the
100 to 110 degree range. As of early this evening, temperatures
and heat index values remained uncomfortable, with values around
90 and 100 degrees respectively.
The next couple of days will be hot, humid, and uncomfortable
across much of the state, with highs into the 90s and heat index
values well above 100 expected at times. Tomorrow shapes up to be
the hottest day though, with temperatures into the mid and upper
90s state wide, and heat index values likely eclipsing 110 across
the state. Values around 115 will be likely in a number of
locations as well. On the night side, lows will be uncomfortable
the next couple of days as well with values only dipping into the
mid 70s in many areas.
Relief will begin to move into the state late Saturday, eventually
dropping highs back into 80s by Sunday and into the work week.
Opportunities for widespread showers and storms will be limited,
but pass through portions of the state beginning later Friday and
through the weekend.
