Heat advisory issued for counties east of Mecklenburg, although Charlotte will still be hot Thursday

A heat advisory has been issued for noon to 8 p.m. Thursday in counties east of Mecklenburg, including Cabarrus, Rowan and Union.

But with an expected high of 97, Charlotte will still be hot.

The National Weather Service issues heat advisories when the expected high temperature and the relative humidity combine to make it feel 105 degrees or greater.

Charlotte’s heat index value is forecast to be 102 degrees Thursday, while the counties to east will be around 105, according to the National Weather Service in Greer, S.C.

Mecklenburg, Union, Cabarrus and Rowan counties were under a heat advisory on Wednesday.

A heat advisory means people should reschedule strenuous activities, wear lightweight and loose-fitting clothes and drink plenty of water.
