ACCUWEATHER: It will take until after the middle of April for cold weather to fully relinquish its grip on the northeastern United States.
A southward shift in the polar vortex caused the first weekend in April to feel more like winter with cold and even snow returning from the Great Lakes to the Northeast.
Spring typically features fluctuations between cold and warm air, but the cold air will have the upper hand for the first half of April.
"It appears as though cold weather will continue through the middle of the month," AccuWeather Meteorologist Ed Vallee said.
Residents should not be fooled with temperatures briefly rebounding for a day or two this week.
The milder surge will occur ahead of storm systems that will track across the northeastern U.S. and open the door for more waves of chilly air to pour in from Canada.
There will also be additional opportunities for snow this week, and not just from the clipper system starting this week.
"A strong storm system will bring rain to end the week with perhaps some snow in the Ohio Valley and the Northeast, especially the interior," Vallee said.
"The strength of the cold [that follows for next weekend] will be a bit less intense and not as long-lasting," he continued, "but killing freezing are quite possible in the Midwest, Northeast and extending all the way down into the southern Appalachians."
Gusty winds will also return with next weekend's cold shot, creating even lower AccuWeather RealFeel® temperatures that will have residents once again thinking the calendar was turned back to winter.
The strength of the storm will determine if damaging winds will once again become a concern.
"Temperatures will rebound the following week," Vallee said, but cautioned that residents will have to wait a bit longer for spring warmth to fully take hold.
"Below-normal temperatures will be the theme for the Northeast through approximately the middle of the month before a warmup to end the month."
