Original story: The storm is expected to move through North Texas overnight into early Sunday, with additional threats of hail, flooding and some tornadoes expected to follow Friday's storm.
Severe thunderstorms are possible across the Dallas-Fort Worth area Saturday evening into Sunday. A flood watch is in effect for much of North Texas through Sunday evening, according to the National Weather Service in Fort Worth.
Officials said the storm was “likely” to develop between 2 a.m. and 7 a.m. Sunday.
A cap, or layer of relatively warm air, held through Saturday afternoon, suppressing storm development. Bureau of Meteorology officials said the storm is expected to pass overnight.
Areas northwest of Dallas-Fort Worth, including Wichita, Jack, and Young counties in particular, were under a tornado watch until 3 a.m. Officials had issued a severe thunderstorm warning Saturday evening around Wichita Falls, about 195 miles northwest of Dallas.
Storms are likely to develop in the area Sunday afternoon and evening, and the Bureau of Meteorology stressed that residents should prepare for overnight storms.
The area could see significant hail, damaging winds and a few tornadoes. The risk of flash flooding is expected to increase west of Interstate 35 Saturday night, according to the NWS.
Rainfall totals of 2 to 4 inches are possible in the Dallas-Fort Worth area, with isolated flash flooding possible and rapidly rising waters in streams, streams and rivers.
The Bureau of Meteorology warned motorists to never drive into bodies of water of unknown depth, and said they should be especially careful in areas with poor drainage, such as low-water intersections and construction zones.
“Remember to stay aware of weather information, have multiple ways to receive alerts, and have a safety plan in place,” said Alison Prater, a meteorologist with the Fort Worth office.
On Friday, the National Weather Service issued watches and warnings for severe storms and tornadoes across north and central Texas. Prater said authorities received reports of video footage of tornadoes in McLennan County (one in the western and China Spring areas) and one near Frost in Navarro County.
Prater said the department will send investigation teams to these three areas on Saturday to assess and determine the route of damage. The team also plans to go to additional areas to see if there were any other tornadoes.
According to the Prater newspaper, 0.41 inches of rain was recorded at DFW International Airport on Friday.
The Bureau of Meteorology said an “unstable weather pattern” starting Friday will continue into the weekend and into next week, with the possibility of afternoon storms. These storms are unlikely to strengthen or become severe between Monday and Wednesday.
A cold front is expected to arrive Thursday, according to NWS forecasts, which will provide more details next week.
