Cold waves, snowy weather to eye northeastern US before winter finally gives up
Following additional waves of cold air into the second weekend of April, the pattern is likely to change, and people in the Northeast may finally be able to say goodbye to winter.
A lobe of the Polar Vortex will remain anchored near Hudson Bay in Canada through this weekend.
In this position, waves of Arctic air will be able to freely sweep from northern Canada to the Upper Midwest and into the Northeast states.
Colder, Arctic air swept across the Northeast on strong winds during the middle of the week.
A second surge of Arctic air is poised to rotate through the region spanning Friday and Friday night.
A simple dry and chilly scenario for the Northeast this weekend is unlikely at this time. Some parts of the region will contend with snow.
As a consolation, with each passing week, the risk of accumulating snow on the roads during the daytime diminishes. For there to be slippery conditions during the middle of the day, it must snow very hard.
However, where it snows at night or early in the morning, when road surfaces are cold, an accumulation can take place on highways, streets, parking lots and sidewalks.
During next week, the Polar Vortex lobe is projected to retreat northward. As this happens, Arctic air is likely to be contained over northern Canada.
One more dose of chilly air may settle in behind a storm with rain and wet snow early next week. However, that air does not appear to be as cold as that of the two cold shots into this weekend.
"As the weather pattern evolves during the middle of April, it looks like cool air will be coming from the Pacific, rather than northern Canada for much of the Northeast," according to AccuWeather Senior Meteorologist Brett Anderson.
When cool Pacific air is exposed to the warming rays of April sunshine, it has a long time to moderate while crossing the United States. By the time this air reaches the East, it should be rather mild.
While the pattern may still bring some brief shots of cool air with cold nights by mid-April, the potential will exist for some long-forgotten warm days in the Northeast.
With the exception of northern New England, the region should be done with accumulating snow events.
