A storm system will soak the northeastern United States and bring another dose of winter weather that will bring accumulating snow to parts of the region.
The first half and last half of this dynamic storm will be like night and day in terms of weather and precipitation type for many locations.
Precipitation began as rainfall on Friday and Friday night with mild conditions entrenched across much of the Northeast.
The second half of the storm will be the colder and wintry part and responsible for some snow away from the coastal mid-Atlantic and southeastern New England.
It's possible that precipitation may hold off until the storm is ready to bring all snow to northern New England later this weekend, according to AccuWeather meteorologists.
There is likely to be no snowfall from Washington, D.C., to New York City, but the northwestern part of this swath is likely to at least have some snow mixing in at the end of the storm during Saturday night and Sunday. Boston is likely to have snowflakes mixing with rain on Saturday night. A few inches may accumulate on roadways well to the north and west of Boston.
Roads and the lowest part of the atmosphere will be warm until cold air catches up during the latter part of the storm, and the lingering mild conditions can be a limiting factor in the amount of snowfall accumulation.

Meanwhile, over the Appalachians, a change from rain to snow is highly likely, and it will occur from southwest to northeast. This changeover to snow will occur during the day Saturday and then continue Saturday night over the mountains in Tennessee, western North Carolina, West Virginia, northwestern Virginia, western Maryland and western Pennsylvania.
Accumulating snow is also possible in the mountains of north-central and northeastern Pennsylvania and is highly likely in western, central and northern New York and New England during Saturday night and Sunday.
A general coating to 3 inches of snow is likely over the central and southern Appalachians. Heavier snow is likely at elevations above 1,800 feet over the West Virginia, western Maryland and south-central Pennsylvania mountains.
Snowfall of 3-6 inches is likely with an AccuWeather Local StormMax™ of 8 inches from northern New York to western Maine as well as in the mountains of West Virginia.
Rain is likely to just end over southeastern Virginia Saturday night.
Enough chilly air will stick around the Northeast to allow for additional rounds of wintry precipitation into next week, but true Arctic air will not follow the storm.
One weak storm is likely to spread flurries and perhaps a snow squall from Sunday night to Monday near and north of Interstate 80 before a larger storm has the potential to bring more snow or rain changing to snow to the Northeast from Tuesday night to Wednesday.
Even though true Arctic air will not follow the storm during the middle of next week, strong winds could squeeze out every ounce of frigid conditions in terms of how it feels. AccuWeather RealFeel® Temperatures are likely to plunge into the teens, single digits and below zero degrees Fahrenheit in the region from Wednesday to Thursday.
