Update on Winter Weather Chances

A strong upper-level disturbance located over eastern South Dakota tonight will continue to move southeastward over the next 36 hours. The position of the upper wave when it moves through the Mid-Atlantic region is favorable for strong lift across central Virginia. The fast movement of the storm system and limited moisture will yield only snow showers and flurries for our area. Surface temperatures will be two to three degrees above freezing, so no travel issues are expected with this system.

A Few Flurries Possible Sunday AM

A quick-moving storm system will dive southeastward out of the Dakotas Friday night, arriving in the Mid-Atlantic Sunday morning. Marginal temperature and moisture profiles will result in only scattered snow flurries across central Virginia, mixing with light rain across southeast Virginia. I'll have another update on this system later tonight.
