A COLD WEATHER ADVISORY has been issued for nearly the entire state. Wind chills will range from +5 degrees to -10 degrees (north). Lows will drop to the single digits and teens - make sure to drip your faucets if your pipes are prone to freezing! Most places will stay below freezing Monday with sunny skies and gradually decreasing winds. Wind chills will stay in the teens. Lows in the teens will continue through early Wednesday. We may not climb above freezing in central Oklahoma until Thursday! Another winter storm system will approach from the southwest, late Thursday through Friday. Widespread snow accumulations are possible. The exact path of the low will make a big difference so stay tuned for updates!
