Storms on Sunday brought considerable rainfall, prompting flood warnings in sections of Oklahoma throughout the early afternoon.
10:30 p.m. Sunday Update: The potential for severe weather and floods across the state is decreasing. Some rain will most likely fall overnight.
2:30 p.m. Sunday Update: Just before 2:20 p.m., the National Weather Service issued a flash flood warning for northeastern Grady and northwestern McClain counties.
The meteorological service said that 4 to 6 inches of rain had already fallen in the area, with an expected rainfall rate of 2 to 4 inches per hour. The areas under caution may see an additional 1 to 3 inches of rain.
The affected areas include Newcastle, Blanchard, Tuttle, and Bridge Creek.

1:10 p.m. Sunday update: Just after 1:05 p.m., the National Weather Service issued a flash flood warning for northeastern Cleveland County.
The meteorological service said that thunderstorms were delivering heavy rain in the area, with 2 to 3 inches already falling. Forecasters predicted a rainfall rate of 1 to 2.25 inches per hour.
The warning will expire at 4:15 p.m.
According to KOCO 5 Meteorologist Joseph Neubauer, the potential of storms continues until 8 p.m. on Sunday, with a high chance of rain across much of the state. The OKC metro area has an 80% probability of rain, and southwestern Oklahoma has an even higher chance.
A level one marginal risk was issued, extending from southwestern Oklahoma to the OKC metro and northeastern Oklahoma. According to Joseph, the storms could bring destructive winds of 50-60 mph, as well as quarter-sized hail in southwestern Oklahoma between Altus, Hobart, and Lawton.
Storms with a severe weather danger should move into western Oklahoma between 10 and 11 a.m., then into central Oklahoma by noon. According to Joseph, it should be a very busy afternoon, and anyone with outside plans should have other options.
Radar indicates that in the early evening hours, more storms with a severe weather threat and heavy rainfall will sweep across the state from the southwest to central Oklahoma.
There is also a risk of rain during the night and early Monday morning. The rain possibilities are shifting east on Monday, and Joseph believes there is no possibility of severe weather.
