One of the factors contributing to the heat wave is drier than normal conditions, said Michael Morgan, a professor in the department of Atmospheric and Oceanic Sciences at the University of Wisconsin-Madison.

The National Weather Service out of Shreveport has issued a heat advisory for the four states region that will run through 7 p.m. tonight.
With maximum heat index values between 105 and 115 degrees, the warning will last until Friday evening for many counties.
“Precautionary/preparedness actions…an excessive heat warning means that a prolonged period of dangerously hot temperatures and high humidity will occur”.
While western Washington enjoys mild, summer temperatures mainly in the 70s, a large portion of the country is dealing with dangerously hot temperatures and high humidity. Vehicle interiors can reach lethal temperatures in a matter of minutes. This will make it feel very uncomfortable and increase the risk for heat stroke, according to the alert from the weather service. Drink lots of water even if you’re not thirsty and wear, loose light clothing. Heat stroke is an emergency, call 911.
The steam heat really kicks in today.
Sweltering conditions remain through Friday, for another windy, brutally hot and extra humid day.
More 90s and storm chances Friday near record highs feeling more like triple digits as the humidity keeps climbing. Heat index readings will top out around 110 in the afternoon.
A cold front is forecast to push toward the Badger State Saturday night, with a line of showers and storms.
Saturday will be partly sunny, with a high in the mid-90s.
