A powerful cold front barreled through the region on Monday and the post-frontal winds picked up dramatically as much colder air poured into the northeastern part of the country. The winds will continue to be strong today from a west-to-northwest direction with gusts of up to 50 mph making it feel even colder than the actual outdoor temperatures. Another blast of Arctic air will push into the Mid-Atlantic region later tomorrow night setting the stage for a very cold start to the new year on Thursday.
In addition to the wind and cold, the next few days will also feature a couple of upper-level “short-wave” disturbances that will rotate through a “long-wave” trough of low pressure centered over the eastern states. As a result, there can be snow showers at various times including late tonight and early tomorrow from one disturbance and again late tomorrow night into early Thursday from a second disturbance. The second “short-wave” is the stronger of the two and small snow accumulations cannot be ruled out as we transition to the new year on Thursday.

A powerful cold front will barrel through the region during the next couple of hours and the winds should kick up dramatically as much colder air plunges into the northeastern part of the country. In fact, gusts can reach 50 mph this afternoon and evening in the Mid-Atlantic region from the usual post-cold frontal direction of west-to-northwest. This incoming blast of cold air will be followed quickly by a second one right around the time we transition to the new year on Thursday and that influx of Arctic air may be accompanied by some snow. As we go through the medium-term, two important changes in the atmosphere will be unfolding, and they can lead to an increased chance of an east coast storm and accumulating snow in the Mid-Atlantic region.

A strong cold front arrives later today and it’ll be mild ahead of it with morning temperatures likely spiking into the upper 40’s. Following the passage of the front, temperatures will drop markedly during the afternoon hours and it turns noticeably colder at night. Winds will be a big factor from later today into Tuesday with gusts to 50 mph on the table throughout the Mid-Atlantic region. Additional cold fronts and upper-level disturbances will pass through the region later this week assuring a cold start to the new year and there can be some snow shower activity at times.

The weather starts off the new week on the chilly side, but temperatures should climb to above-normal level from Tuesday through the rest of the week. In addition to the milder weather, it looks like it should stay dry for the bulk of the week.

A fresh infusion of Arctic air from southeastern Canada in the overnight hours will set the stage for a significant winter storm in the Mid-Atlantic region from Friday afternoon into late Saturday. The cold air mass will be anchored by strong high pressure over SE Canada which will stay in place during the event. A thin layer of slightly above-freezing air in the upper atmosphere will nose into the southern Mid-Atlantic region creating conditions for sleet and freezing rain in many of those areas. The storm will bring substantial accumulating snow across the northern Mid-Atlantic region and a mixed bag of precipitation across the southern Mid-Atlantic. Travel conditions will deteriorate rapidly once the precipitation gets underway this afternoon and will remain very difficult right through tomorrow with temperatures at or below freezing in many areas through much of the event. Looking ahead, another Arctic outbreak reaches the Mid-Atlantic region on Monday night and a second shot around New Year’s Day.
Here is a breakdown for the Mid-Atlantic’s I-95 corridor:
NYC metro, central/northern NJ, east-central PA, NE PA: primarily a snow event with accumulations in the 5-9 inch range, isolated higher amounts, some sleet can mix in at times, surface temperatures stay below freezing through the event
Philly metro, northern DE, southern NJ: snow and sleet should dominate with some freezing rain, snow accumulations in the 1-3 inch range and there will likely be a thick layer of sleet, I don’t expect surface temperatures to get above freezing through most, if not all, of the event.
DC metro, northern MD, northern VA: mainly a combination of rain, freezing rain and sleet, a touch of snow is possible with little to no accumulation, watch for an ice buildup across the normally colder northern suburbs…temperatures will hove close to the freezing mark during much of the event.
