A storm snarling travel in the Midwest re-energized in the northeastern United States with heavy rain in part the mid-Atlantic and substantial snow and ice for part of New England early this week.
For people taking a New Year's holiday trip, the storm will throw a wrench into travel plans following relatively quiet weather conditions at Christmastime.
Widespread and even heavy precipitation for some was predicted to last through Monday night.
Rain in store for most major cities
Many major cities across the region received a thorough soaking of rainfall. One-quarter to 0.50 of an inch of rain was common from Washington, D.C., to Pittsburgh and New York City.
The weather was miserable in New York City and Philadelphia yesterday with periods of rain, foggy episodes and a brisk easterly wind.
Temperatures were expected to reach record challenging levels near 70 F in Washington, D.C., late yesteray evening.
Cold air wedge to promote snow, ice in New England
About 100 miles north of New York City, cold air will linger and lay the foundation for wintry precipitation, including a substantial buildup of ice.
The key to how much snow versus ice occurs will be how successful a layer of warm air is able to extend northeastward.
"Should the warm air race in a few thousand feet above the ground, then little snow, but a significant amount of ice can occur," AccuWeather Senior Meteorologist Brett Anderson said. "Should the cold air resist this warm wedge, then parts of central and northern New England could be buried under a foot of snow or more."
"A change to snow is possible over central New England on the backside as a secondary storm forms, strengthens and drags colder air in," according to AccuWeather Senior Meteorologist Brett Anderson.
The zone from central Massachusetts to southwestern Vermont and northeastern and east-central New York state are experiencing a major ice storm with a buildup on the order of 0.25 to 0.75 of an inch thick that could trigger widespread power outages.
What will the weather be like after the storm?
In the wake of the storm, on New Year's Eve, colder air will funnel southeastward from central Canada, across the Great Lakes and into the Northeast.
The air will not be as cold as that which blasted the region a few days prior to Christmas, it will be cold enough to trigger some lake-effect snow near the lower Great Lakes and also cause some snow showers to wander through the central Appalachians and New England from Tuesday night to New Year's Day.
Experts urge motorists to be alert once again for rapidly changing weather conditions on the highways from sudden snow showers. Although temperatures will overall be higher during this snow shower event compared to last week's squalls, roads may still become slippery and snow-covered in the span of a few minutes, leading to dangerous conditions.
