1:00 PM | ***Snowstorm hits the Mid-Atlantic region late Sunday night and Monday with the "bullseye" region for the heaviest snowfall from DC to Philly***

Discussion

A winter storm will affect the I-95 corridor region from DC-to-Philly-to-NYC from late Sunday into early Monday evening. The “bullseye” region for the heaviest snowfall from this storm is likely to occur in the southern half of this area from DC-to-Philadelphia and eastward to the Jersey Shore with the New York City metro region to the north of the heaviest snowfall. Indeed, there will likely be a sharp cutoff of the snowfall on the north side of the accumulating snow band with virtually no effects in New England.

California is getting slammed today by the storm that will quickly cross the country and spread precipitation into the Mid-Atlantic region later in the day on Sunday. Temperatures will actually climb to near 40 degrees on Sunday in Philly and NYC and into the 50’s across the DC metro region with no problems at all on the roadways. Temperatures will then absolutely crash in the overnight hours as Arctic air pours in behind a frontal passage so that by early Monday morning Philly and NYC will be well below freezing with accumulating snow falling and the DC metro region will be in the process of changing over from a wintry mix to heavy snow.

Temperatures will continue to plummet during the day on Monday right on through the 20’s and into the teens and then could actually bottom out by early Tuesday morning near an incredible 0 degrees in many suburban locations in the I-95 corridor. Icing is likely for a brief time in the NYC and Philly metro regions before the changeover to snow and perhaps for a more extended period in the DC metro region, but the vast majority of what falls on Monday in the I-95 corridor will be in the form of snow. In fact, the cold air will plunge so far to the south and east by later Monday that significant snow will accumulate from the Jersey Shore to southeastern Virginia.

Snowfall estimates at this time are as follows: NYC: 4-8” with minor icing before the changeover PHL: 8-12” with minor icing before the changeover (highest amounts to the south and east and lesser amounts to the north and west) (8-12” at the Jersey Shore with moderate icing) DC: 8-12” with moderate icing before the changeover

Stay tuned, additional updates later this weekend at “thesiweather.com” and there is still some time to go before the event.
