Heat Advisory and Current Conditions
A Heat Advisory is currently in effect for Sherman, Texas, signaling dangerous heat levels for the area. The National Weather Service has issued this moderate-severity alert to warn residents of the oppressive conditions. As of this evening, the air temperature stands at 86F, but the heat index makes it feel like 95F.
