As the snow kept on falling Wednesday, the National Weather Service's forecast of total accumulation remained largely unchanged.

Meteorologists said Wednesday that the heaviest snowfall is still expected across Hampton Roads and northeast North Carolina. Totals for the Tidewater region remains a spread of 5 to 10 inches over the course of the storm. Those totals include what has already fallen, and snowfall can be closer to a foot in some areas.

Jeff Orrock, meteorologist-in-charge at the weather service office in Wakefield, said snow is likely to continue Thursday, thanks to a second system coming into the area.

"There may be a break in between these two systems, and we'll see how much of a break we get," Orrock said. "Some models think that it could be a several-hour break, where other models say that the two are almost going to run together. There may not be that much of a break, so we'll see how that plays out."

All snow and winter precipitation is expected to end by 4 p.m. to 7 p.m. in Hampton Roads and the Eastern Shore. Snow showers are still possible in isolated areas. Across Hampton Roads, closures and disruption to services continue. Schools have canceled or gone to remote options, and most city services have been postponed.

Officials are still encouraging residents to avoid all driving. The weather service warned that travel on Thursday will likely be "extremely dangerous" because of the snow and ice. Trucks with the Virginia Department of Transportation are out working around the clock to treat and move snow off the interstate and state-maintained roadways.

Because snow is falling 1 to 2 inches per hour, VDOT reported Wednesday that it will likely take multiple passes with plows to get roads drivable.

Temperatures will struggle to rise above freezing on Thursday, and lows will be in the teens. Wind chills across Hampton Roads, though, could be in the single digits. Wind gusts could reach about 35 mph, making visibility outside difficult.

"This could lead to some issues with blowing snow, especially since the last round of snow will be light and easily moved around," meteorologists said in a briefing Wednesday. "Winds should diminish Friday afternoon and into the weekend."
