The National Weather Service has issued a Heat Advisory in effect from Noon until 9pm Tuesday.
The forecast high is expected to reach 106 degrees Tuesday; however, the heat index could reach 110 or higher. Temperatures will climb to the 100-degree mark by noon across much of south Central Texas.
High temperatures should return to the upper 90s by the weekend.
The NWS issues a heat advisory when a period of abnormally hot temperatures is expected. The combination of hot temperatures and humidity will combine to create a situation in which heat illnesses are possible. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.
