Assuming the current forecast by the National Weather Service (NWS) office in Blacksburg is correct, rain and snow showers will begin Saturday around 1 p.m. and kick off the third snow storm in March 2018 just three days after the so-called start of Spring.

This one, projections say, could well be the worst one of all.

Writes Kevin Myatt, weather guru of The Roanoke Times:

Waves of heavy snow are expected to occur by evening, possibly accumulating at rates of 1 to 2 inches per hour at times in some locations with totals of 4-8 inches and locally up to 10 looking likely for the Roanoke and New River valleys and along the Blue Ridge south of Roanoke westward to the I-77 corridor.

Notes NWS in its winter storm warning:
