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.
