Wednesday is forecasted to be a very hot day with temperatures in the upper 90s and heat index values around 100° to 105°, with some areas approaching 107°. The heat index is a ‘feels like’ value for how hot it will feel in the shade. It is even more dangerous when in direct sunlight.

The National Weather Service in Detroit/Pontiac has issued Heat Advisories for all counties north of M-59, and an Excessive Heat Warning for all counties south of M-59 to the Ohio border. The Heat Advisory is for high humidity levels boosting how the ambient temperature feels to us, from the actual upper 90s to feeling like 105 degrees. The Excessive Heat Warning is for the same reason, only the temperature will feel like 107° in some areas. These warnings and advisories go into effect at 12 pm Wednesday and expire by 8 am Thursday.
