Today's Forecast

Today's Forecast Image
  • 91°
  • 69°

Once some morning storms moved out of northern Siouxland, it turned hot and humid with highs close to 90 and a heat index that hit 100 degrees by mid-afternoon.  We have a frontal boundary sitting in Siouxland so we'll keep a very small chance of an overnight storm in the forecast, but most of us will stay partly cloudy with even some patchy fog possible.  Tomorrow is going to be hot and humid again and we can't rule out an isolated storm popping up.  By far, the best chance of rain arrives Friday night when heavy rain could fall, especially in western Siouxland.  After another hot day Saturday, temperatures will start to come down some into the beginning of next week, with some chances of storms continuing into mid-week.

Chief Meteorologist Ron Demers
