      **Severe T-Storm Watch for much of Siouxland, including Sioux City, until 10 pm**

      Cooler air has pushed into western Siouxland and as that airmass continues to push into this very humid day, scattered strong to severe storms are going to be possible into our Monday night.  Strong winds and large hail will be the primary threat although isolated tornadoes can't be ruled out.  The biggest threat will be through the evening hours on Monday although some storms will continue into Monday night as well.  We could still see a slight chance of thundershowers continue into Tuesday morning but I think we'll get a break for much of Tuesday before rain chances will once again start to get better by Tuesday evening into Tuesday night.  In fact, Tuesday night through Thursday could become a rainy period across Siouxland and that rain could become heavy with over 2 inches possible in many locations.  We still could see some shower chances into Friday but the rain should be much lighter by that time.  Temperatures will not be as hot as what we've been seeing as highs on Tuesday should be closer to 80 degrees with highs only in the 70s from Wednesday through Friday.
