529 PM CDT Fri Oct 19 2018

High temperatures this afternoon hit the upper 60s, a few locations
did hit 70 degrees. A weak cold front passed through which has 
shifted winds to a northwest direction. This did bring through a few 
passing clouds and light showers, but did not drastically reduce 
temperatures. 

Cloud cover has been patchy across the rest of the Midwest and Plains
as a few waves of energy have moved through. Although there were a 
few showers, the weather was not all too active. 

Tonight, temperatures will be in the lower 40s. The winds may be gusty
at times overnight, as there will still be influence from the passing
front earlier this afternoon. Most of Iowa should stay dry.
Northwesterly winds will keep conditions cooler Saturday with highs in
the mid 50s, but will rebound back into the lower 60s Sunday. Next
week will be quiet, with next rain chances forecast for Thursday.
