COLD WEATHER SAFETY INFORMATION
Cold air continues to push into Oklahoma as a strong arctic front quickly moves to the south.
Temperatures will continue to drop dramatically. By 7 p.m., temperatures across northwestern Oklahoma will be down in the upper 20s and lower 30s.
Although most ice accumulations will be light, a few spots may be around one-quarter inch.
With strong winds, even light ice accumulation will result in downed tree limbs and possibly damage to power.
This could result in sporadic power outages. Outside of bridges and overpasses, no significant travel problems are expected. Monitor this situation closely..
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.
