Extreme Heat Warning Issued as Central Texas Faces Hottest Day of the Year

Central Texas faces a significant heat risk this Thursday, with Austin forecast to reach 98 degrees, the hottest day of the year so far, according to the KVUE Weather Team. The National Weather Service has issued an Extreme Heat Warning for the I-35 corridor and Coastal Plains counties as heat index values are expected to reach between 110 and 115 degrees.

Why is Central Texas facing extreme heat this Thursday?

The peak heat is driven by a combination of surging temperatures and tropical humidity, according to the KVUE Weather Team. Dew points in the mid- to upper 70s, paired with saturated soils from recent rainfall, will push heat index values higher.

While Austin’s actual temperature is forecast at 98 degrees, “feels like” temperatures could briefly approach 117 degrees in some locations. This combination creates what the KVUE Weather Team describes as a significant heat risk for the region.
