Dallas started today on the pleasant side at about 64°F, but the cool comfort will not last. Temperatures are set to rocket into the low 90s by afternoon, turning the day into an early taste of summer heat just as an Ozone Action Day lands on the region.

Afternoon Heat And Breezy Conditions

The NWS Fort Worth forecast keeps highs near 91°F on both today and tomorrow, with south-southeast winds around 5 to 15 mph. By Friday, those breezes pick up, with gusts expected to reach 25 to 35 mph, the kind that make yard work feel hotter and send unsecured patio chairs on a short trip across the deck.

This stretch of warm, dry weather is expected to hold through Saturday before a new system approaches and boosts thunderstorm chances later in the weekend.

Air Quality Alert

The National Weather Service has also issued an Air Quality Alert for Wednesday, noting that the Texas Commission on Environmental Quality has called an Ozone Action Day for the Dallas-Fort Worth area. People with asthma, COPD, or other lung conditions are advised to avoid long or intense outdoor activities while ozone levels run high.

Weekend Storm Watch

Rain chances stay low through Saturday, but the pattern shifts late Sunday as a weather system moves in and raises the odds of thunderstorms. The forecast puts the chance of showers and storms near 60 percent on Monday, with some storms capable of producing strong winds and frequent lightning.

If you have outdoor plans next Sunday night into next Monday morning, keep a backup indoor option ready in case storms roll through.

What To Do

Plan outdoor chores, workouts, or dog walks for the cooler morning hours, and keep water and shade on hand for kids and pets during the hotter parts of the day. Before afternoons turn gusty, secure loose items like lawn chairs, umbrellas, and trash bins so they do not tumble down the block.
