| While forecast uncertainty is still high two days in advance, we offer a forecast of what locations up the East Coast can expect from Tuesday night into Thanksgiving Day. Whether or not this storm turns into a travel nightmare will depend heavily on where the rain-snow line sets up on Wednesday afternoon — something that has been difficult to pin down thus far. | While forecast uncertainty is still high two days in advance, we offer a forecast of what locations up the East Coast can expect from Tuesday night into Thanksgiving Day.

| However, most of the East Coast, and in particular the I-95 corridor, can expect at least rain, possibly mixing with or changing to snow during the later half of Wednesday. Interior locations — at least 30 miles west of I-95 — are very likely to see accumulating snow, and travel will be challenging. | However, most of the East Coast, and in particular the I-95 corridor, can expect at least rain, possibly mixing with or changing to snow during the later half of Wednesday.

| If the flakes fly in eastern North Carolina, they are likely to be short-lived and will not accumulate in any meaningful way. Temperatures are expected to remain mostly above the freezing mark — around 40 degrees — for the duration of the storm. Some flurries are possible Wednesday evening and night when the temperatures drop, assuming a slower storm. Chances are the bulk of the precipitation will have cleared out of North Carolina before it gets cold enough to see any meaningful or disruptive snow. | If the flakes fly in eastern North Carolina, they are likely to be short-lived and will not accumulate in any meaningful way.

| The Weather Prediction Center is giving the Raleigh area a 10 to 20 percent chance of snow accumulation over 2 inches, and that chance is mostly on the northwestern side of the city.

| Snow becomes more likely northwest in the Piedmont at higher elevations. Though with temperatures hovering around and above the freezing mark, accumulation is expected to be minimal, with little disruption to travel. | Snow becomes more likely northwest in the Piedmont at higher elevations.

Snow will mix in through the late morning and early afternoon starting in the northwest and moving toward the southeast. |
| We expect a rain-snow mix east of I-95, with a low chance of snow accumulation. In D.C., we’re forecasting about an inch of snow by Wednesday night, which will be wet and heavy. Baltimore may see a slightly higher total than D.C., but not by more than an inch. In the near northwest suburbs, the chance of accumulation grows, with the best forecast at around 1 to 3 inches of snow accumulation. In the farthest western and northwestern suburbs, expect more along the lines of 3 to 6 inches of snow. | We expect a rain-snow mix east of I-95, with a low chance of snow accumulation.

| For Philadelphia itself, most of the precipitation is expected to fall in the form of rain, though snow will mix in on Wednesday night. A sharp gradient between rain and snow is expected, of course, roughly along the I-95 corridor. East of this gradient, only 1 to 2 inches of snow may accumulate, but west of the gradient, as much as 8 inches could fall, with higher amounts accumulating in the Poconos. | For Philadelphia itself, most of the precipitation is expected to fall in the form of rain, though snow will mix in on Wednesday night.

| Light precipitation will begin in the Boston area in the form of rain as early as Tuesday night, but the storm won’t get cranking in earnest until Wednesday afternoon. Snow could begin to mix in as early as Wednesday morning, though it’s not clear at this point whether that will transition to all snow on Wednesday afternoon and evening for Boston itself and the surrounding coastal areas. Further inland, rain will turn to snow in the morning or early afternoon hours of Wednesday, and stay that way through the duration of the storm. Precipitation is expected to end by the morning hours of Thanksgiving Day. | Light precipitation will begin in the Boston area in the form of rain as early as Tuesday night, but the storm won’t get cranking in earnest until Wednesday afternoon.
