Snow and ice to sweep through northeastern US through Tuesday

A storm will barrel across the northeastern United States with periods of snow, rain, an icy mix and perhaps thunder through Tuesday.

Snow and an icy mix swept through western and central New York and Pennsylvania early Monday evening, leaving a slippery glaze on cars, sidewalks and roads.

Motorists should be prepared for changing weather conditions as the zone of wintry precipitation sweeps through New England through Tuesday. Even less than an hour of a bit of sleet and snow can make roads slippery and dangerous for high-speed driving.

With a period of snow, sleet and freezing rain expected across Pennsylvania through Tuesday, the Pennsylvania Department of Transportation (PennDOT) is imposing restrictions on certain trucks and other vehicles and limiting speed limits.

Some of the areas most likely to turn icy the fastest will be bridges, overpasses and stretches of roadway that are typically shaded from the sun.

For many in southern New England, any snow, sleet and freezing rain at the onset can changeover to a mix of rain and snow or plain rain on Tuesday.

Before the changeover, the Tuesday morning commute could, therefore, be slower and more hazardous. This includes around Boston.

Extra time, as well as extra safety precautions should be taken into consideration as workers head out the door that morning.

The storm is predicted to be more consistently wintry farther north into Tuesday night.

"A general 3 to 6 inches of snow will fall across northern New England," according to AccuWeather Meteorologist Brett Rathbun, since precipitation is likely to be just snow for the duration of this event.

Snow may total in excess of 6 inches in a few localized areas of northern New England. That means skiers can look forward to plenty of fresh snow.

"Outside of the mountains, temperatures in Portland, Maine; Burlington, Vermont; and many other lower elevations in northern New England may see temperatures climb well above freezing on Tuesday afternoon," according to AccuWeather Senior Meteorologist Kristina Pydynowski.

As the leading edge of colder air arrives, locally gusty showers, some with thunder and lightning are forecast to develop across the Ohio Valley and lower Great Lakes region during Tuesday afternoon.

This zone is forecast to move into the central Appalachians during Tuesday night, where rain may change to snow and bring a small accumulation before ending.

A warming trend will not be the theme for the rest of the week with winter's cold and more snow set to make a comeback later this week.
