The National Weather Service says a cold front is heading toward Oklahoma, bringing with it a slight chance of wintry precipitation.
Forecasters say temperatures in the Panhandle will be 10 to 25 degree below normal on Sunday and Monday -- and some areas may not rise above freezing on Sunday. Breezy winds are also predicted, resulting in wind chill values in the teens and 20s for much of the day.
The rest of the state should see temperatures in the 20s and 30s with the coldest wind chills in northern Oklahoma.
Forecasters say some areas could see light snow during the day Sunday and overnight, but it's not expected to accumulate.
