Key Messages
- Mostly dry and cool today with limited potential for scattered storms along southern peripheral counties dependent on exact location of overnight frontal boundary.
- Low-moderate confidence (20-60%) in subsequent precipitation overnight Wednesday into Thursday morning increases in amounts (1" - 2") and confidence (60-80%) Friday into Saturday. Location of highest rainfall rates limits confidence for areal and river flooding (<10%), potentially higher for flashier rivers in northeast Iowa (Turkey) and southwest Wisconsin (Kickapoo) should highest amounts be realized in these spots.
