Record-breaking heat wave hits Texas with partial blame on rain.

Austin broke a heat index record with a value of 118 degrees on Wednesday afternoon, partially due to rain from a few weeks ago combined with high temperatures. The city is expected to cool down slightly over the next several days, but temperatures and humidity levels are still expected to be well above normal. Austin and Travis County officials have warned residents of the risks of heat and encouraged heat safety and awareness, with the city using libraries and park facilities as cooling centers open to the public as the heat wave continues.
