Despite a spring-like feel to the air yesterday and today – with temperatures passing 50F in spots – accumulating snow is in the forecast. Read on below…
A strong frontal zone, marking the leading edge to much colder air, will pass through the Northeast today and tonight. This boundary will sag south of the area overnight tonight and arctic air will surge back into New England. At the same time, an abundance of jet stream energy will be swinging across the eastern half of the United States, initiating storm development off the Eastern Seaboard.
While the brunt of this developing weather system will remain well offshore, the interaction between the southward moving frontal zone, jet stream winds aloft, a low level wind off the water and the growing ocean storm will create a shield of snow across the area Sunday, Sunday night and Monday.
Overall, this won’t be a major weather system. While snow and snow showers will linger around the area for almost 30 hours (call it 7AM-ish Sunday to Noon-ish Monday), most of the snow will fall lightly with only a few bursts of steadier snow likely now and then. Total accumulation should be on the order of 2 to 5 inches…but it should be quite manageable given the long duration.
That said, temperatures will be falling to the freezing mark and then into the 20s as Sunday transitions to Sunday night and sideroads / untreated surfaces will become slick and snow-covered at times. The Monday morning drive in to work could be a bit hazardous / slow going around the area with falling snow and very cold temperatures.
