UPDATE: A winter weather advisory is in effect until 1 p.m. Wednesday for northern, southwest and central Oklahoma.
Forecasters say freezing rain and sleet are likely to accumulate on power lines and tree limbs. Strong northwest winds will also make it more likely for lines and limbs to fall.
Power outages are most likely, according to the forecast, in central and north-central Oklahoma.
The risk for severe storms and tornadoes is less than earlier forecast, but dangerous thunderstorms are still possible.
ORIGINAL POST: It's a day to be weather aware. The National Weather Service says a storm system could bring baseball-sized hail and isolated tornadoes to parts of Oklahoma today. Forecasters say severe storms will likely begin firing late this afternoon.
The greatest risk for the severe storms is near and east of a line from Seymour, Texas, to Lawton to Yukon to Ponca City. That includes the Oklahoma City metro.
Areas west of that line, including Woodward and Altus, are at a slight risk for severe weather.
Forecasters say the storms could bring 2-inch-diameter hail, wind gusts of up to 80 mph and isolated tornadoes.
A cold front will follow the storm system into the state, and temperatures are expected to drop well below freezing in western Oklahoma. Forecasters say a mix of sleet and freezing rain in possible in some areas early tomorrow.
