DFW Weather Alert: Severe Storms, Flash Flooding & Sweltering Heat Expected—Here’s the Hour-by-Hour Forecast

Early-morning storms drench the Metroplex The new workweek started with a bang across Dallas-Fort Worth as a slow-moving line of thunderstorms rolled through before sunrise. Pockets of torrential rain, frequent cloud-to-ground lightning and 40-50 mph wind gusts caused brief power flickers and ponding on low-lying roads, especially along the I-35E and I-20 corridors. Rainfall totals generally ranged from 0.50″ to 2.00″, but a few unofficial backyard gauges in southern Dallas County topped 3″. Storm threat fades, steamy air returns The National Weather Service in Fort Worth expects leftover showers to exit by late morning as the upper-level disturbance lifts northeast. Skies will transition to a mix of sun and clouds, pushing Monday’s high to about 88 °F. With dew points near 75 °F, the heat index will still feel like the mid-90s—so keep water handy if you’ll be outdoors once the rain clears. Heat builds Tuesday through Friday • Tuesday: Sunny and hotter. High 93 °F. Morning humidity eases slightly, but the afternoon heat index will flirt with 100 °F. • Wednesday–Friday: A strengthening ridge—often dubbed the “Texas heat dome”—parks overhead. Expect highs of 93-95 °F and muggy lows in the upper 70s. Heat advisories may be issued if the index clips 105 °F, so monitor official DFW weather updates. Weekend outlook Forecast models hint at a subtle wind shift Saturday that could pull Gulf moisture back into North Texas. For now, a 20-30 % chance of late-day thunderstorms is in play, mainly east of Dallas. Otherwise, the weekend stays typically August-hot with highs around 94 °F and plenty of sun. What this means for you • Commute: Wet pavement this morning will dry quickly, but watch for slick spots beneath overpasses and on frontage roads. • Outdoor plans: Shift strenuous activity to early morning or evening; sunscreen and electrolytes are must-haves. • Pets & people: Never leave children or animals inside parked cars—the cabin temperature can top 120 °F in minutes. • Energy bills: Consecutive 90-degree days put strain on the grid; set thermostats to 78 °F and run ceiling fans counter-clockwise. Bottom line Today’s showers offer only temporary relief. The DFW weather pattern flips back to classic summertime heat after lunchtime and stays that way most of the week. Keep tabs on changing forecasts, hydrate often and be ready for another round of pop-up storms when the weekend rolls around.
