Key Messages

  • Warm and predominantly dry conditions continue through most of the work week. However, some smaller rain chances (30%) will be possible from late Thursday into Friday mainly across northwestern IA.
  • Drier and breezy conditions over the weekend could lead to some locally elevated fire concerns with more widespread concern possible by Saturday.
  • Better rain chances (20-40%) and cooler temperatures look to return early next week, but confidence in details remains low.
