High Heat Coming To An End - Cooler Weekend Ahead

 

Today ends the string of hot and humid days, thanks to a cold front dropping southeast across the region. The weekend promises much cooler and less humid conditions - along with shower and thunderstorm chances.

  • A Heat Advisory is in effect for portions of northeast Iowa through central Wisconsin until 7 pm
  • Daytime heat indices from 90 to 100 degrees

This heat and humidity may cause an increase in heat related illnesses.

Be proactive by checking on those most susceptible to heat related illnesses - small children, the elderly, and those with medical conditions. Individuals left isolated without air conditioning has led to numerous deaths in recent heat waves.
