CLAYTON, Mo. (AP) – As hot, humid weather bears down on the central U.S., officials are saying heat is to blame in the recent death of a Missouri woman.

The St. Louis County medical examiner’s office confirmed Tuesday that heat was to blame in the death of an elderly woman found in her home last week. Authorities didn’t release any additional details about the woman or her death.
Heat and humidity is expected to build across a huge swath of the U.S. over the next few days.

The National Weather Service has issued excessive heat watches and heat advisories for much of the Plains, Mississippi Valley, Midwest and South through the weekend. Highs are forecast to be well into the 90s and low 100s by the end of the week, with humidity making it feel about 10 degrees warmer.
