Weather Summary for Iowa
National Weather Service Des Moines IA
523 PM CDT Sat Sep 23 2017

Hot and humid conditions prevailed across much of the region as gusty
south winds brought temperatures into the upper 80s to lower 90s late
this afternoon. A stalled boundary extended southeast South Dakota
into northeast Nebraska through central Minnesota was the focus for
cloud cover and a few thunderstorms along and northwest of this
boundary. In fact, northwest of the boundary, temperatures ranged in
the 50s. For instance in Orange City in far northwest portions of
Iowa had a 5 PM temperature of 88 degrees, while Mitchell, South
Dakota just about 150 miles west northwest had a temperature of 57

Yet another hot and muggy day is forecast for Sunday across much of
Iowa, southeast Minnesota, eastern Nebraska, Missouri and Illinois as
the aforementioned boundary remains stalled. The boundary finally
begins to press southeast on Monday and looks to provide a sharp
gradient of temperatures across Iowa for highs. The northwest portions
will see highs in the upper 50s while the east to southeast look to
rise into the upper 80s. Storms are possible on Monday and Monday
night as the front slowly drifts southeast. Additional thunderstorm
chances are forecast on Tuesday. Much cooler air looks to filter into
the region by Tuesday and Wednesday and remains throughout the
remainder of the work week.
