Heavy rain had dissipated by noon Wednesday in Collin County, but some residents were waiting for high water to recede from their lawns after receiving 4-8 inches of sudden rain.
The National Weather Service has issued a flash flood watch until 7 p.m. Wednesday in North Texas, which means conditions are right for dangerous accumulations of water to happen suddenly.
Just ask the residents of Fairview in northeast Collin County recorded 8.16 inches of rain for a 24-hour period that ended 7 a.m. Wednesday, according to the National Weather Service in Fort Worth.
McKinney, meanwhile got nearly 5 inches of rain, the weather service said.
"They got creeks out of their banks and water in people's yards," said Dan Shoemaker, a weather service meteorologist.
Some streets were closed in McKinney and Allen, said Jason Lane, of Collin County's emergency management office. No high-water rescues, however, were reported.
Westbound Industrial Boulevard in from Airport Road to Texas 5 was closed because of high water, Lane said.
Also, portions of Parker Road in the city of Parker, Texas 5 in Fairview were closed, as well as Stacy Road between U.S. 75 and Texas 5 in Allen, Lane said.
Meanwhile, police in McKinney were watching Wilson Creek where it flows beneath U.S. 75 and also high water on North Brook and Park View streets, north of the creek, a dispatcher said.
Southeast Dallas County was also received about 4 inches of rain overnight, said Jennifer Dunn, also of the weather service.
Also, an urban and small stream advisory was issued for Parker County, where as much as 2.52 inches was recorded overnight, Shoemaker said.
"Some low-lying areas were hit with some nuisance-type flooding, but nothing significant yet," Shoemaker said.
The heavy rains are the result of a Canadian upper-level low pressure pressure system that reached the Texas Panhandle over the weekend and then began sliding southeast toward North Texas.
The system was swirling over the region early Wednesday. It has been mingling with moist air from the Gulf of Mexico and creating scattered thunderstorms.
But Tarrant County, at noon, was in the eye of the low-pressure system, so no rain was falling there, although some scattered showers were popping up over surrounding areas, Shoemaker said.
However, the low pressure system was expected to continue drifting east Wednesday afternoon.
"It's slowly moving over our area and then it will lift to the north and northeast," Dunn said.
Wednesday held a 60 percent chance for rain, which will dwindle to 20 percent on Thursday, according to the weather service forecast.
The high temperatures will be in the mid 80s Wednesday and low to mid 90s Friday and Saturday. Friday and Saturday should be dry, the weather service said.
