Ice, Snow to Impact Travel in Northeast Tuesday Night Into Wednesday

Snow and ice that developed over interior mid-Atlantic on Tuesday will spread slippery travel northward into early Wednesday over the interior Northeast.
Not enough snow and ice will occur to cause widespread power outages in this situation. Some people in northern New England were still without power on Sunday in the wake of the storm that hit just before Thanksgiving. A few small tree limbs may break, which could cause minor sporadic power disruptions.

The wintry mix is following only about 24 to 36 hours after temperatures climbed into the 50s and 60s on Monday.
A shallow push of cold air moved in on Monday night ahead of the wintry precipitation, slashing temperatures by as much as 30 degrees compared to highs from Monday.
According to AccuWeather Meteorologist Ed Vallee, "Warm air trying to move up from the south will be forced to ride up over top of the shallow layer of cold air near the ground into Wednesday."

This process caused some sleet and rain to break out from portions of northern Virginia to parts of Ohio and southern Pennsylvania, during Tuesday morning.
Vallee added that wintry travel conditions will spread northward Tuesday night into Wednesday morning.
Temperatures in the upper 20s to lower 30s F near the ground will allow some of the rain to freeze on colder surfaces.
Bridges, overpasses and other elevated surfaces will be the first to turn icy.
Along I-95, temperatures are likely to be warm enough to prevent black (clear) ice from forming. However, a mix of sleet and rain will spread northeastward in the swath from Washington, D.C., to Baltimore, Wilmington, Delaware, Philadelphia, New York City and Boston for a time. Slippery spots may develop in these cities' northern and western suburbs.

As the wintry mix ends in southern areas, some wet snow, sleet and rain will then spread into northern Pennsylvania, northern New Jersey and New York state Tuesday afternoon and evening.
Metro areas that could experience slippery travel Tuesday night include State College and Scranton, Pennsylvania; Binghamton, Buffalo and Albany, New York; Rutland, Vermont; Worcester, Massachusetts, and Portland, Maine.
Just enough of a wintry mix can fall to cause slow and slippery travel along parts of the New York Thruway and Massachusetts Turnpike and portions of the I-80, I-84, I-88, and I-91 corridors during Tuesday night.
The wintry mix will then shift into northern Maine and neighboring Canada on by Wednesday morning.

"As warmth overtakes the region, any wintry mix will end or change to plain rain from south to north later Tuesday into Wednesday,' Vallee said.
Temperatures will continue to bounce around for the remainder of the week and are forecast to rebound into the 40s and 50s over much of the region by Wednesday.
