Here’s the latest from the National Weather Service Office in Blacksburg, as of 10:30 AM this morning, a winter weather advisory went into effect at 8 AM this morning and will remain until noon Sunday.
A fast moving low pressure system will slide southeast out of the Midwest and into the Tennessee Valley later today before passing offshore the Carolinas by early Sunday. Precipitation, in the form of snow, will overspread the area starting early this morning and then continue into tonight and early Sunday. The snow will change to a mix of freezing rain and sleet west of interstate 77 later today. There will be a narrow corridor where the precipitation remains all snow. At this time it appears the corridor of heavy wet snow will bisect our region from the northwest, impacting southern West Virginia from Bluefield into the western New River Valley of Virginia...and possibly spilling into the Roanoke Valley, and the Virginia Blue Ridge west of Rocky Mount and Martinsville. Snow amounts of 4 to 8 inches or more are expected within this corridor.
The specific forecast for Martinsville calls for rain likely after noon today and mixing with snow after 3 PM, but with the temperature up around 42 degrees, little or no snow accumulation is expected. Tonight is a different story. There is a 100 percent chance of snow and sleet before 3 AM, then all snow between 3 AM and 5 AM, then a mix of rain and snow after 5 AM tapering off and ending by around 8 AM. We are expected to get at least 2 inches and possible 4 inches of snow by the time this event ends Sunday morning.
