Extreme Heat Safety

An Extreme Heat Warning remains in effect through 8pm Friday for North Texas, where afternoon high temperatures up to 108 degrees can be expected. A Heat Advisory remains in effect through 8pm Friday across Central Texas, where afternoon heat indices up to 109 degrees can be expected. Remember to drink plenty of water, to take frequent breaks in the shade or A/C, and to look before you lock your vehicle!

Exceptionally hot weather will persist over the next few days, with triple-digit temperatures expected each afternoon. However, an upper-level disturbance and a stalling front will bring a slight chance of storms to the region. Should you encounter a storm, remember: “When thunder roars, go indoors.”

Temperatures will remain well above normal due to a persistent strong ridge of high pressure overhead, though a slight chance of rain could return by the middle of next week.

As August continues, we have received several questions asking why we are using 'unseasonable' to describe this week of high temperatures! This is because the high temperatures across North and Central Texas have been much closer to our record highs for August than our normal average highs. This pattern is expected to continue, with the possibility for afternoon temperatures at DFW on Saturday to tie or exceed the record high.

Extreme heat is expected this week. Everyone is at risk from the dangers of extreme heat, but these groups are more vulnerable than most. Ensure that your loved ones and neighbors are safe from the heat and remain Weather-Ready. weather.gov/safety/heat-during
