Snow Totals & Storm Recap

The last band of light to moderate snow is now moving east of I-95 and should be out of the state by 11-11:30PM. Western and northern Virginia got the lion's share of the snow today. Here is a glimpse of some of the totals as of 9:30 PM:



Totals were much less in Central VA. Here are some of the totals reported on our weather chat in the Storm Room:

1.0" Hanover
1.0" West Henrico
1.0" Louisa
1.0" Buckingham
1.0" Appomattox
0.8" Woodlake
0.5" Powatan Courthouse
0.5" Tappahannock
0.3" Brandermill

Temperatures will drop into the upper 20s tonight, so untreated roads could become slick. You can find the latest road conditions at http://www.511va.org/. We're expecting temperatures to climb above freezing from 9 to 10 AM Thursday morning.

Mapping Out The Next 12 Hours

Here are some maps to help you plan the next 12 hours. The shades of purple represent snow, pink is a mix, green and yellow are rain and gray is cloud cover. You can see that most the the wintry weather will end just after midnight.




Updated Winter Weather Map: 12:30PM Wed

As of 12:30 p.m. Wednesday, this is the updated Winter Storm Warning and Winter Weather Advisory map for central Virginia:

North-central Virginia counties are now included in the Winter Storm Warning, including Spotsylvania and Stafford Counties. This warning lasts until 4 a.m. in northern Virginia for heavy accumulating snow. The expected accumulations remain about the same in our area:

The change over to snow is already occurring in western Virginia at Noon as the potent upper low pressure system approaches. I still expect bursts of heavy, wet snow to occur this afternoon and evening as this upper system passes overhead. The Richmond metro is still on track to see the change over from rain to snow in the 4-7 p.m. window. Here's a snapshot of the upper vorticity max directly over central Virginia this evening at 7 p.m., when nearly all of central Virginia will have seen the change from rain to snow:

Snow will end from west to east tonight, exiting the state shortly after midnight. The wet pavement in the area will freeze by Thursday morning as temperatures dip into the upper 20s. This will create slick and hazardous conditions on the roads Thursday morning.
