Parts of North Texas were expected to receive 1 to 3 inches of rain through Sunday, with some areas receiving up to 4 inches.
The National Weather Service in Fort Worth has issued a flood watch for most of north and central Texas until 7 p.m. Sunday as a strong to severe storm moves through the state.
Large hail, damaging winds and isolated tornadoes are possible, the weather service warned.
The most significant impacts are expected to be flooding of poorly drained low-lying urban areas and rapid rise in water levels in streams, streams and rivers, the Bureau of Meteorology said.
With so much recent rainfall, the ground is already saturated and localized flooding is possible in Dallas, according to forecasts from KXAS-TV (NBC5).
Dry weather is expected on Monday, but some clouds will remain in the sky. Forecasters say rain could return to Dallas-Fort Worth on Tuesday and continue through at least Friday.
High temperatures in Dallas will be in the 80s until it cools down a bit on Friday, and will remain throughout the weekend, the weather service said.
Lows will remain in the 60s throughout the week.
