Dallas started this day under mostly clear skies and muggy air, with early morning temperatures in the low 70s and barely a breeze to stir things up. The sun is expected to rule most of the day, sending afternoon highs into the mid to upper 80s and keeping it plenty sticky for anyone with outdoor plans. On top of the heat and humidity, there is an ozone-related air-quality advisory in effect that could put a damper on strenuous outdoor activity.
Today Through Wednesday
Sunday is shaping up mostly sunny and calm, with a high near 87 expected today, and a similar warm setup for Memorial Day tomorrow, when highs should climb near 88. The next meaningful shot at rain arrives on late Tuesday into Wednesday, when showers and thunderstorms are expected to become more widespread. Some storms could drop locally heavy rainfall. These details are outlined by the National Weather Service Dallas/Fort Worth.
Air Quality Alert
The Texas Commission on Environmental Quality has declared an Ozone Action Day for today, for the Dallas-Fort Worth area, in effect through the late afternoon. On Ozone Action Days, TCEQ advises limiting strenuous outdoor exertion, consolidating errands, and avoiding vehicle idling to help reduce ozone exposure for sensitive groups. Full guidance is available from the Texas Commission on Environmental Quality.
Commute And Event Tips
Drivers heading out early should be ready for patchy morning mist or fog in low-lying spots east of US 75/I-645, which could briefly cut visibility for the earliest commuters. If you have outdoor Memorial Day plans, pack water, find some shade, and have a backup spot under cover in case a late-day shower pops up. If you are traveling from Tuesday to Wednesday, keep a close eye on updated forecasts, as slow-moving storms could dump heavy rain over small areas and cause brief street flooding on area roads.
