It has been almost two years since Washington, DC received more than 1 inch of snowfall, but it could change significantly by later Sunday. Winter warnings continue in the city from Sunday evening, with 4-8 inches of snow possible. Additional snow is expected to fall on Monday.
CNN meteorologist Taylor Ward says, “It is rarely easy to forecast snowfall in the nation’s capital, but there is growing confidence that the DC area will develop on Sunday and Monday.”
A major winter storm is in the works that could bring 10 inches of snow to the nation’s capital. This would end the 709-day streak that Washington, DC has gone without more than 1 inch of snowfall.
“This is only the second time the 788-day streak ended in 2013,” says CNN meteorologist Brander Miller.
On Sunday morning, more than 110 million people from the southern Great Lakes to New England were under winter weather alerts. The effects of the storm have already been felt as heavy snow fell in northern Illinois and central Indiana, causing travel headaches.
The storm will not be powerful nor strong until Monday morning, as it will hit the coast. For many along the eastern seaboard this will be a long-term phenomenon as the system will be slow to exit. Snow will periodically fall from DC, Philadelphia, New York City to Boston over the next three days, ending gradually from southwest to north-east.
Major effect expected
There will be heavy snowfall with strong winds, reducing visibility and power loss. Travel disruptions will be widespread from ground to air as storm coats accompany fresh snow on roads and runways. Snowfall rates of 1-2 inches per hour were recorded late Saturday evening near the Chicago suburbs, where snowfall is forecast to be up to 9 inches by Sunday night. As the storm moves eastward, it will reorganize and intensify. New Jersey, southern New York, eastern Pennsylvania and parts of Maryland will have the most snow accumulation, where up to one foot of snow is possible.
Snow and sleet accumulation is also a concern for parts of North Carolina, Virginia, Maryland and West Virginia. The highest totals are likely to fall north of Charlotte and Raleigh where up to 1/2 inch of snow is possible.
The warm region of this storm is making many showers and embedded thunderstorms in Central and Southeast America today. Expect rain in Atlanta to leave the region before the start of work on Sunday.
Areas west such as St. Louis and Springfield, Illinois will see more rain / snow mix than Sunday evening. Exactly how much ice will stick to the ground is uncertain.
A week after Iowa’s areas were covered with snow, Hockey State could see a few extra inches by Sunday night.
A developing nor
The National Weather Service office in Baltimore and Washington DC said, “Snow will increase from the southwest until late Saturday and early Sunday morning.”
Changes in sleep and cold are likely, from Sunday afternoon to Monday.
As with any nor’easter, the forecast is uncertain in snow aggregates because so little depends on the precise track of pressure.
“There is general consensus among forecast models that moderate to heavy snowfall will occur in Pennsylvania and New Jersey in medium-term Virginia, but there remains some uncertainty on the exact track of low pressure on Monday,” said Ward’s model. “This will have a significant impact on how much snow falls in New England in New York City. A storm system that tracks parallel to the coast will provide as much snowfall as possible, while a more eastern track out of the sea will bring snow across New England Will limit the total. “
Seeing 4 inches of snow or a foot can make a difference in places like Boston and New York City.
Philadelphia’s NWS office is forecasting more than 6 inches of snow with gusts of wind and 45 mph with “significant blowing and drifting snow.”
The NWS office in Boston had already indicated the storm and its possible effects on Friday.
The storm will move away from the coast by Wednesday.
