Dallas Weather Alert: Severe Storms, Flash Floods & Tornado Threat Tonight

Updated Dallas Weather Forecast: Thunderstorms Early Week, Steadier Heat by Memorial Day North Texans woke up to rumbles of thunder as a potent spring storm system rolled across Dallas–Fort Worth this Monday morning. Forecasters expect scattered heavy downpours, frequent lightning and gusty winds through the morning commute, with the high topping out near 80 °F (27 °C). Rain chances taper late this afternoon, but lingering clouds will keep the evening muggy with lows in the upper 60s. What to Expect the Rest of the Week • Tuesday: Mostly cloudy, spot showers before noon, then drier. High 79 °F, low 66 °F. • Wednesday–Thursday: A cooler north breeze knocks highs back to the mid-70s, but humidity sticks around. Spotty drizzle possible early Wednesday, otherwise partly cloudy skies. • Friday – Memorial Day Weekend: Sunshine returns and temperatures rebound—mid-80s Friday, upper-80s by Sunday. South winds increase, pumping moisture back into North Texas and pushing the heat index into the low 90s. Storm Threats and Safety Tips for Dallas-Fort Worth 1. Lightning & Flash Flooding: Downpours may drop 1–2″ of rain in less than an hour. If water covers the roadway, “Turn Around, Don’t Drown.” 2. Gusty Straight-Line Winds: Secure patio furniture and trim dead branches ahead of tonight’s storms. 3. Hail Potential: Quarter-sized hail can damage cars—park in a garage or under a sturdy awning if possible. 4. Heat Creep: By the holiday weekend, UV indices soar. Hydrate, rotate outdoor activities to the morning, and apply SPF 30+ sunscreen. Travel & Event Impacts • Flights: Morning departures from Dallas Love Field and DFW International could face delays due to lightning-induced ground stops. • Commute: Ponding on I-35E near Downtown Dallas and the “Low Five” interchange tends to snarl traffic during heavy rain. • Memorial Day Events: Lake Lewisville, White Rock Lake and backyard barbecues look mostly dry, but pack a pop-up canopy for an isolated late-day storm. Why This Pattern Matters May is historically Dallas’ wettest month, averaging 5 inches of rain. This week’s frontal boundary is classic late-spring North Texas weather: flash-flood-producing storms followed by rapid warming. The quick transition to summerlike highs near 90 °F signals the onset of the region’s long hot season—plan A/C tune-ups now to avoid peak-season breakdowns.
