The answer to the title of this blog is YES. We are tracking the chance for another round of rain/sleet/snow to impact Virginia and North Carolina overnight and into Monday. A Winter Storm Warning is still in effect for areas in pink until Monday afternoon. These areas will likely have the highest snow accumulations. A Winter Weather Advisory is in effect for all areas in purple until Monday afternoon. These areas could see minimal accumulations.

This doesn’t mean we won’t see any sleet or snow across the Southside. I think we could see sleet and snow mixing in across the Southside at times, but I don’t think it will accumulate with the rain falling and temperatures above freezing. Ground temperatures are in the 50s right now, so it will be hard for the snow to overcome the warm ground and accumulate.

Rain showers moved into the region earlier this afternoon and will continue overnight. We should begin to see the transition to snow and sleet across our northern areas just before midnight tonight. Reminder: Blue is snow, green is rain and pink represents a snow/sleet mix.

Latest computer models are showing the precipitation becoming more scattered in nature by tomorrow morning. But if we do see snow across our northern zones overnight, then roads could be slippery, especially bridges and overpasses. Temperatures will remain above freezing overnight, except across parts of the Middle Peninsula, Northern Neck and Eastern Shore. Keep in mind that travel could become more difficult in these areas by tomorrow morning.

We may get a break from the rain/sleet/snow from the late morning into the early afternoon before a new round of snow/sleet moves back into the area. This is a new feature that the computer models are picking up on. Here is Future Trak at 3 PM. This round of snow may have a better chance at sticking on grassy areas and cars since temperatures will be just above 32┬░.

After looking at all of the new data, here is the latest snow totals map through Monday afternoon. Computer models are now showing a little bit more sleet and less snow, so I have brought totals down a bit. Best chance for accumulating snow will be north of Gloucester. Keep in mind that if we see more of a mix, then these accumulations will be too high. When you see a mix, you usually do not see much accumulation because the rain helps to melt the snow and the sleet.

The wind could also be a problem on Monday. Expect sustained northeasterly winds from 20-30mph close to the coast and 15-25mph for inland spots. Winds could gust up to 40mph and up to 45mph along to the coast. That will put wind chill values into the 20s during the day tomorrow. Tides will be running higher than normal due to the strong northeasterly winds and the full moon tonight. We could see nuisance tidal flooding during high tide on Monday.
