Although the calendar says that spring arrives on Friday, a blast of cold air is set to delay the season change across the East.
A last-minute snowstorm across the Northeast on Friday will appropriately bring astronomical winter to an end before the official season change to spring occurs at 6:45 p.m. EDT.
As that storm departs over the weekend and merges with another system across Canada, a rush of cold air will charge into the Great Lakes and Northeast and delay spring for millions of people.
High temperatures are expected to tumble as a cold front sweeps in over the weekend, falling 5 F to 15 F below the normal for this time of the year on Sunday.
Cities such as Detroit, Pittsburgh, Washington, D.C., Buffalo, New York City, Philadelphia and Boston will all face the chilly drop in temperature.
Overnight lows late this weekend into early next week will again dip back to below freezing in the I-95 corridor from Baltimore to Boston. Locations across the Appalachians will drop down into teens and perhaps the single digits in the coldest valleys.
According to AccuWeather.com Meteorologist Evan Duffey, while February was a record cold month for many, March has been more of a mixed-bag when it comes to mild and chilly days.
"New York City and most places in the Northeast will see the coldest air since March 7 return to the region," said Duffey.
Any snow that melts during the day due to the increasingly stronger March sun angle will be at risk for freezing into black ice at night. Motorists are urged to travel with caution.
The cold air will even reach the Carolinas by the start of the new week. After reaching the upper 60s and lower 70s over the weekend, highs in the 50s will be felt for many on Monday in North Carolina.
High pressure will allow for some sunshine Sunday and into the new workweek, which will help in some ways.
"Longer daylight hours and strengthening sunshine will negate some of the chill," said AccuWeather.com Meteorologist Alex Sosnowski.
Unfortunately, a long-lasting warm spell is not in the forecast anytime soon as more waves of cold air will continue to move in.
"Below-average temperatures are likely to outnumber warmer-than-average days by at least two to one from the Upper Midwest to the Northeast through early April," said Sosnowski.
Normal temperatures are now increasing about a degree every few days, which is something to look forward. The worst of the cold is now in the rearview mirror as the spring season settles in.
