A storm system that brought thundersnow and heavy snow to portions of the Piedmont is moving out, leaving behind a wide swath of 2-5 inches of snow.

Rain transitioned to snow across the area around 6 p.m. and thundersnow was reported in several cities.

Thundersnow is a thunderstorm when the air is cold enough to produce snow instead of rain. Just like in the spring and summer, instability is created when the air above the ground is much colder than the air at the ground.

Tonight, at ground level we are certainly chilly, but above it is much colder and as the upper disturbance that Van has talked about this week moves overhead, it will continue to produce thundersnow with heavier pockets of snowfall.

Warmer ground temperatures will allow the snow to slowly melt overnight, however roads will be treacherous on Friday morning.

Drivers are urged to stay off the road if possible.

The roads are expected to get slushy and tonight as temperatures dip to the upper 20s, we may also see some of this become a more solid ice on elevated surfaces in the  morning.
