Large swaths of Texas are forecast to be hotter than 99% of the world Wednesday as Dallas’ stretch of scorching hot days was expected to reach a peak of 107 degrees, according to meteorologists.

The heat index value, which measures what it feels like outside based on air temperature and humidity, for Dallas could be as high as 115, according to KXAS-TV.

The National Weather Service in Fort Worth issued an excessive heat advisory for most of North Texas, including Dallas, Collin, Denton and Tarrant counties, though 8 p.m. Central time Wednesday. The weather service’s excessive heat warning said parts of Texas will experience “high temperatures from 105 to 110 in the west and heat indices as high as 115 in the east.”

This week’s heat is also affecting programs and businesses: the Cedar Ridge Preserve limited its hours this week and Fort Worth canceled the afternoon time slot of its daily cattle drives through the Stockyards for the entirety of July.

“Only the Sahara Desert & Persian Gulf area will be as hot or hotter than the Lone Star State,” Ben Noll, a meteorologist with New Zealand’s National Institute of Water & Atmospheric Research, tweeted last week, saying Texas would be hotter than 99% of the rest of the world.
