2:00 PM | While nothing major appears to be on the horizon, an active weather pattern is setting up with multiple chances for snow

Discussion

Now that colder air has returned to the Mid-Atlantic region following the passage of a very strong cold front, the question becomes “are there any upcoming chances for snow”? The answer is “yes, there are multiple chances”, but each of the systems involved will likely be somewhat limited in moisture content. Nonetheless, it is likely to be cold enough for snow for each system along the I-95 corridor from DC-Philly-NYC, and small accumulations are possible in at least parts of the Mid-Atlantic region.

The overall weather pattern is setting up so that fast-moving disturbances will drop down from south-central Canada into the northeastern US over the next several days. In fact, it looks like there will be at least three such disturbances to deal with between early tomorrow and the middle of next week that could bring snow showers or even steadier snow to the region.

Disturbance number 1 will spread some snow shower activity early tomorrow in the I-95 corridor and while a small accumulation can occur anywhere in this region between DC and NYC, the best chance for accumulations will probably be in the area from DC to the Delmarva Peninsula to South Jersey.

Disturbance number 2 is destined to throw some snow in this region late Saturday night and Sunday. This disturbance will move towards the Mid-Atlantic coast over the weekend and a fairly widespread snow event is likely to take place. Once the low pressure area reaches the coastline, it may intensify pretty rapidly which could actually allow it to drop some appreciable snow along the eastern New England coastline.

Disturbance number 3 will drop out of south-central Canada early next week and will likely affect the Mid-Atlantic region around Tuesday with some snow or snow showers. Again, as with the first two disturbances, its moisture content will be rather limited, but accumulations cannot be ruled out.

Stay tuned as this looks like an active stretch of weather over the next several days for the Mid-Atlantic region and there may even be a fourth disturbance by the end of next week.
