Where is the Snow?

I captured this graphic at 5:40 PM tonight. Just by looking at the radar image, you would think that heavy snow was falling across the Eastern Shore, Northern Neck and Middle Peninsula earlier this evening. But, the surface observations did not indicate any snow reaching the ground. This means that the snow was evaporating before it reached the surface (Virga). The lower levels in the atmosphere are very dry, too dry to support precipitation at this time.

Evaporation is a cooling process. This means the lower levels of the atmosphere will continue to cool until we can get snow falling all the way to the ground. Our Future Trak model has some snow showers reaching the Southside around midnight with more of a wintry mix possible for North Carolina. Best chance for precipitation tonight with be across the Southside and N.E. North Carolina, so many areas will end up staying dry.

The precipitation will be very light since it will take a while for the atmosphere to moisten up. Little to no accumulation is expected. Any snow/rain will taper off before sunrise on Sunday. We should see decreasing clouds Sunday afternoon with highs in the mid 40s. The weather will stay relatively quiet this upcoming work week with temperatures around normal for this time of year.
