The culprit – before the rapidly deepening storm over the Carolinas from the Tennessee Valley – will bring moisture from west to east to the DC area just after midnight. Although the combination of rain and drizzle can kick things off, the nighttime temperatures are such that the snow that lasts during the day should stay cool for long periods of time.

Ryan Miller, a meteorologist with Storm Group 4, said: “As the cold winds continue to spread from the north to the region, that rain will turn into snow, and then the winds will continue to cool and turn from snow to snow.” WTOP.

But like many winter storms in recent memory, there is a catch: tight sloping models of snow accumulation north of the country’s capital point to exactly how big differences small nudges can have in the path of the system throughout Sunday. Falls – and where. The exact structure of heavy ice sheets is very difficult to predict and may also be a determining factor.

All of these totals are highly dependent on how long it takes for temperatures to drop below freezing from Monday morning. According to Hurricane Group 4 meteorologist Brianna Permansolo, rain or sleet will not help with much snow.

“It’s a kind of storm, it’s on the beach, and there’s a tight slope between where the rain falls and there’s nothing,” Miller said.

The forecast may change somewhat, but any results that come to the road on Monday morning will cause headaches. Plan slippery conditions on streets, stairs, sidewalks and driveways.
