Early indications suggest wintry precipitation is possibly Saturday as the winter storm transitions from Midwest states to the Mid-Atlantic and Northeast, while heavy snow could fall in some areas. 

We noted on Monday how the Global Forecast System (GFS) data shows Old Man Winter will return to the Northeast on Friday with average temperatures from Washington, D.C., to Boston around 25 to 34 degrees. This could make conditions ripe for a snowstorm over the weekend. 

The National Weather Service (NWS) is projecting that snow and ice could be seen on early Saturday for Mid-Atlantic states, with mixed precipitation in the afternoon. The further north, the higher the probability of significant snowfall. 

"Although confidence continues to increase on the potential for a winter storm for parts of our area (above average confidence for this time range, in fact), it is still too early to get into specifics on timing and amounts of different precipitation types given ... this is still 4 to 5 days away," NWS said Tuesday. 

Henry Margusity, a meteorologist for Weather Madness, provides several weather charts that indicate the storm could quickly impact tens of millions of folks in the Mid-Atlantic and Northeast this weekend.
