Oklahoma is expected to face several rounds of potentially severe storms Wednesday, Oct. 14, after thunderstorms move through parts of the state Tuesday night. The forecast includes hail, a low tornado threat and locally heavy rain, with some areas potentially receiving more than 3 inches by the time the system passes. The overnight threat is focused on northwest and western Oklahoma, where storms could continue into early Wednesday. Some locations could receive more than 4 inches of rain overnight, according to the forecast. Nearly all of the state is expected to have some risk of severe weather Wednesday. A slight risk covers communities including Oklahoma City, Chickasha, Lawton, Elk City, Altus, Stillwater, Ada and Kingfisher. A lower, marginal risk is forecast for parts of the far north and northwest, including Alva, Woodward, Seiling, Cheyenne and Ponca City, as well as Ardmore and southeastern Oklahoma. The tornado threat is rated 2 on a 1-to-10 scale and includes central Oklahoma, including the Oklahoma City metro, along with parts of the southwest and northeast. Storms could develop as early as 8 a.m. Wednesday. The first wave is forecast to move northeast from southwest Oklahoma, reaching the Oklahoma City area around 10 a.m. and eastern Oklahoma near lunchtime. A lull is possible from about 2 to 5 p.m., before another round moves in from the southwest. That second wave could reach the metro around 7:30 p.m. Rainfall totals could top 3 inches around Chickasha, Lawton and parts of Cleveland County. Much of the state is forecast to receive 1 to 3 inches, while the Panhandle and southeastern Oklahoma could see up to an inch. More storms may develop and continue east across the state Thursday morning.
