SALISBURY — After a balmy day of rain, falling temperatures herald in the potential for black ice tonight, the National Weather Service warns.

Temperatures could fall below freezing overnight across much of the Piedmont, according a statement from the weather service. The threat should ease after sunrise.

Cold weather is moving after a stormy evening. Thunderstorms are possible until about 10 p.m. Clearing skies will follow, with the low forecast to be about 30. Westerly winds could hit 20 mph before easing.

While it will be blustery in the Piedmont, as much as inch of snow could fall on higher elevations in the mountains as temperatures fall into the 20s.

The high in Salisbury on Thursday is forecast to be about 50, with a low of about 30. Skies are expected to be clear.
