What To Know
The average first 100-degree-Fahrenheit day in cities such as Austin typically arrives in mid-July. Instead, meteorologists now predict some of the highest-ever May temperatures in recorded history, which could set hundreds of daily records throughout the state.
"This is the type of weather that we anticipate at the end of July, beginning of August—not May," FOX Weather meteorologist Britta Merwin said. "We're losing like two months of comfortable air."
The NWS said that parts of south-central Texas, including the cities of Austin and San Antonio, could see heat index values up to 109, with the service warning that hot temperatures and high humidity could lead to heat illnesses.
"Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, check up on relatives and neighbors," the NWS advised.
Elsewhere in the state, heat index values up to 112 were forecast for inland Kleberg, Nueces, and San Patricio Counties on Wednesday. Up to 114 would be possible in Duval, Jim Wells, La Salle, Live Oak, McMullen, and Webb Counties.
The service added that a moderate risk of heat-related impacts on Tuesday would increase to a major to extreme risk on Wednesday.
"This kind of extreme heat in May is not just unusual—it's a clear signal of our changing climate," said Kristina Dahl, vice president of science at the nonprofit Climate Central.
"Temperatures this high, this early in the year, would have been extremely rare in the past. But, due to human-caused climate change, these dangerous heat waves are becoming more frequent, more intense, and more disruptive."
