Weather Summary for Iowa
National Weather Service Des Moines IA
552 PM CDT Tue May 22 2018

Overall it ended up a pretty nice day across a good chunk of the
state. Some morning to early afternoon showers and storms made their
way across western and southern parts of Iowa, but for the most part
faded away by mid-afternoon. The rest of the state say generally
mostly clear to partly cloudy skies and highs in the upper 70s.
Northeast Iowa was an exception temperature wise though with highs
only into the low 70s. As of early this evening, much of Iowa remained
fairly comfortable with temperatures in the 70s in most spots and
partly cloudy skies. 

The story moving forward is that summer is trying to make its way into
Iowa. Highs will be the warmest of the season throughout the week, 
with much of the state likely to see mid to upper 80s throughout the 
rest of the work week and weekend. Fortunately, extreme dew points are
not expected, so heat index values should only top out into the low 
90s at times. Regardless, given that it will be the first stretch of 
relatively hot weather, please stay hydrated and cool during any 
outdoor activities. Showers and storms should move through parts of 
northern Iowa this evening and overnight, with the potential for some
locally heavy rainfall. Then later in the week, beginning Thursday 
night, showers and storms return and opportunities linger into the 
weekend. At this point in time the severe weather threat is low 
tonight and later in the week, but an isolated strong to severe 
thunderstorm may be possible.
