High temperatures will stick around through the July 4 holiday in metro Detroit after a boiling hot weekend.  We'll still be in the upper 80's today.  We're looking at low 90's on the Fourth.

The heat index is the term weather forecasters use to describe what the air temperature feels like when combined with the relative humidity.

According to the Detroit Free Press, the heat wave is caused by a high pressure system parked over the central Appalachian Mountains.  It's drawing up air from the southwest, which is hot and moist.

The temperatures had metro Detroiters looking for ways to beat the heat.  DTE Energy reported more than 1,100 customers without power Sunday.  Click on the above link for more information.
