Ray predicts 2 to 5 inches of snow could fall for parts of the Metroplex. Up to 8 inches is forecasted to fall in counties closer to the Red River. "Not all of this will stick at first but expect our first accumulating snow in almost a year," Ray said.

The National Weather Service said a tenth of an inch of ice could accumulate on raised surfaces, such as bridges, and some areas could get up to a quarter inch. But the main travel impacts are expected to be from sleet and snow.

North Texas is bracing for a wintry mix of snow and rain that is expected to begin overnight Wednesday as the National Weather Service upgraded several North Texas counties, including Dallas, from a winter storm watch to a warning.
