Dallas is waking up under gray skies around 61°F, with a damp commute on tap and scattered showers slipping across the city. Light rain and a few rumbles of thunder are fair game today, but the main event is still ahead: a steadier, heavier batch of rain late tonight that lingers until tomorrow.

Forecasters say shower coverage will ramp up today before tomorrow turns into a full-on rain day, with the heaviest totals south of Interstate 20. Much of the metro can expect about 1 to 3 inches of rain, with some far-southern counties picking up close to 4 inches and lighter amounts north of I-20. That kind of soaking brings an elevated risk of urban and flash flooding in low-lying neighborhoods, according to the National Weather Service.

Timing And Commute

This morning's drive may only see spotty showers, but coverage should increase from late morning into the afternoon, with on-and-off thunderstorms in the mix through the evening. A brief lull is possible late Thursday before the true soaker settles in overnight and hangs on through Friday. That timing could slow the Friday rush hour, and some streets could become impassable for short periods as rain piles up.

Tomorrow, northeast winds will turn breezy with gusts up to about 25 mph. Expect a wet, blustery setup that can cut visibility, slick the roads and generally make traffic more of a slog than usual.

Flooding Risk

Areas south of I-20 and portions of the southern suburbs are most exposed to the higher rainfall totals and will need to be watched closely for street flooding and ponding. Drivers are urged not to plow through standing water or low-water crossings; local crews may shut down roads if things get dicey. Keep weather and traffic alerts turned on, and have a backup route ready if your usual path to work or school dips through low-lying stretches.

Travel And Airport Note

If you have a flight tomorrow, build in some cushion time. Heavy rain and embedded thunderstorms can trigger delays and occasional ground holds. Check live flight status before heading out on the DFW Airport site and confirm details with your airline. Local transit and ride-hailing pickups may also move slower when the rain is coming down hard, so plan for longer waits and slower transfers.

Weekend Outlook

By tomorrow evening, the rain should start to taper from west to east, setting the stage for a much nicer stretch of weather. Saturday looks sunny with a high near 74°F, and by Sunday into next Monday, temperatures rebound into the upper 70s and low 80s with a drier, more comfortable feel for outdoor plans. Before that, expect a cooler, damp setup tied to the late-week rain, followed by a clear rebound for the weekend.

Quick tips: grab the umbrella for today and tomorrow, steer clear of standing water on the roads, and leave earlier than usual for Friday errands or commutes. We will post updates if any watches or warnings are issued.
