The winter equinox officially occurred on Tuesday night at 638 PM EST, which means that winter has now arrived in the Capital Region, but in reality it is only a formality because winter weather has been firmly in place for several weeks now.
A seasonably cold and winter-like air mass will remain in place over the region for the next several days with a few chances of snow showers and a greater chance of snow by the end of the Christmas weekend.
A coastal storm parked off the northeast coast will send some energy onshore on Wednesday and bring some scattered snow showers and flurries to the region by the afternoon and evening. Some areas, especially north and east of the Capital Region, could pick up a light accumulation of 1 to 3 inches by Wednesday night, with everyone else seeing a light coating to an inch. High temperatures will be in the mid 30's with breezy conditions.
An area of high pressure will then slide east into the region to end the week as the ocean storm slowly pulls away, allowing things to dry out. High temperatures will remain seasonably cold in the upper 20's to near 30 degrees into Christmas Day.
All attention will then shift to a developing storm system over the middle of the country and lower Tennessee Valley. Some computer models are trying to turn this storm up the east coast by Sunday, potentially bringing a significant snowfall to the region. The exact track, as well as eventual strength of the low is yet to be determined, but stay tuned as things are likely to become more clear over the next several days. Temperatures will remain slightly below normal averages into the beginning of next week with high's in the mid to upper 20's.
