BUCKHANNON — Wax up those sleds: Upshur County is set to receive more than six inches of snow as a winter storm barrels through Sunday.

The National Weather Service office in Charleston upgraded the previous winter storm watch to a warning on Saturday, while also increasing the snowfall prediction.

“Heavy snow possible. Total snow accumulations of 6 to 10 inches,” reads the winter storm warning, which runs from 9 a.m. Sunday through 1 p.m. Monday.

“Travel could be very difficult,” the NWS warns. “The hazardous conditions could impact the morning commute Monday. In addition, power outages will be possible. Visibilities will be reduced at times in heavy snow. Along higher elevations, winds could gust as high as 35 mph.”

The Charleston office cautions that the storm remains a challenging one to forecast.

“While uncertainty continues to exist with the exact snowfall amounts any location will see, confidence is high that 4″ or more of wet snow will occur across the entire region, with 10″ or more in the mountains,” the NWS said Saturday morning. “There is also a potential for light ice accumulations from sleet and freezing rain.

“Travel impacts are certain, especially Sunday afternoon through Sunday night, during the height of the storm, when snowfall rates will exceed 1″ per hour in bands of heavy snow. This will be a heavy, wet snow which will likely cause power outages in areas that receive the highest snow totals.”

Light snow will continue to fall Monday, with cold temperatures to remain throughout the week, with highs in the 20s and 30s and lows dipping into the teens.

“Snow showers will linger behind the main storm Monday into Monday night with additional light accumulations likely,” according to the Charleston office. “Sub-freezing temperatures Monday night increases risk for black ice from refreeze which may affect Tuesday morning commute.”

Schools are already scheduled to be closed Monday for Martin Luther King, Jr. Day.
