A potent winter storm that blanketed parts of the state with snow and ice is forecast to exit Oklahoma and the southern Plains on Friday.

The National Weather Service said snow may fall on the back side of the system as it tracks eastward, but the precipitation should end from west to east.

On Thursday, a mixture of snow, sleet, rain and freezing rain fell, coating surfaces with ice. Temperatures ranged from 26 degrees in Guymon to 40 degrees in McAlester. The mercury peaked at 33 degrees in Altus, Bartlesville and Tulsa and hit 34 degrees in Oklahoma City.

Temperatures on Friday should range from the 20s in most spots to near 40 in southeast Oklahoma. Forecasters expect temperatures to tumble into the teens and 20s Friday night.
