Dallas rolled into this morning under clear skies, mid-80s warmth, and a steady southerly breeze that is only the opening act. Afternoon highs are expected to top out around 99°F on Friday, July 10, 2026, with heat index values climbing into the low 100s, potentially reaching 103 to 105°F by midafternoon. It is a good day to ease up on strenuous outdoor plans in the peak heat and keep water handy for kids, pets, and anyone working outside.
Afternoon Winds Pick Up And Storms On The Horizon
Southerly winds near 10 mph will strengthen into gusts of 20 to 25 mph this afternoon and tonight, which can kick up dust in drier spots and make the heat feel even more relentless. A pattern shift late tomorrow ushers in the return of shower and thunderstorm chances, with the best odds from next Sunday through next Tuesday, along with an isolated flooding risk where storms decide to park and dump rain. Timing and impact details are laid out in the local forecast from the National Weather Service Fort Worth.
How To Stay Cool
The City of Dallas is urging residents to lean on air-conditioned public spaces such as libraries and recreation centers during the hottest part of the day and to check in on older neighbors and pets. For those who need a dedicated cool-down spot, the city keeps an updated list of cooling centers and other heat-relief options. You can find hours and locations on the City of Dallas cooling centers page.
