Dallas is starting today with clear skies and temperatures around 82 degrees, but the calm morning will give way to dangerous afternoon heat. The high is expected to reach 101 degrees, with heat index values climbing as high as 105 and potentially reaching 109 in parts of the region.
Heat Advisory Covers Thursday Afternoon
A Heat Advisory remains in effect through 8 p.m. today as hot temperatures and humidity raise the risk of heat-related illness. The National Weather Service Fort Worth recommends drinking plenty of water, wearing loose, lightweight clothing and moving strenuous outdoor work to the early morning or evening.
Winds will stay light at first, then increase to roughly 10 mph from the northeast and east-northeast during the afternoon. The combination of blazing temperatures and lingering humidity will make outdoor errands, exercise and afternoon events especially taxing.
Rain Chances Stay Low, But Storms Could Turn Gusty
Dallas has only a small chance of rain today, with isolated showers or thunderstorms more likely across western North Texas and Central Texas. Any stronger storm could produce brief gusty winds or small hail, even though widespread rain is not expected.
Ozone Action Day Adds An Air-Quality Concern
Thursday is also an Ozone Action Day for the Dallas-Fort Worth area, with atmospheric conditions expected to support higher ozone pollution. The Texas Commission on Environmental Quality recommends reducing emissions by carpooling, avoiding drive-through lines, conserving energy and keeping vehicles properly maintained.
Tomorrow will bring another sunny day with a high near 100 degrees, followed by highs around 101 Saturday and Sunday. Overnight lows will only fall to the upper 70s, so patios, athletic fields and outdoor work sites may not get much relief after sunset.
Triple-Digit Heat Lingers Into Next Week
The hot pattern is expected to continue through next Wednesday, September 2, with highs near 100 next Monday and Tuesday and around 101 next Wednesday. Rain chances remain near zero most days, while dry vegetation and afternoon humidity dropping into the 20% to 30% range will keep the risk of new fire starts elevated.
Anyone spending time outside today should take frequent breaks in air conditioning or shade, check on neighbors and relatives who may be vulnerable to heat, and never leave children or pets in a parked vehicle. Confusion, fainting or other signs of heat stroke require immediate emergency help by calling 911.
