Although the calendar says that spring arrives on Friday, a blast of cold air is set to delay the season's warmer conditions 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.
Cory Morrison · Follow · Top Commenter · Filing/Labelling/General Assistant with Industrial Supply Products at Independent Distributors Inc.At least this March is better than last year's in the Great Lakes.- Cory Morrison · Follow · Top Commenter · Filing/Labelling/General Assistant with Industrial Supply Products at Independent Distributors Inc.Why do you keep making all of these unrealistic predictions anyways? Predicting below average temperatures is realistic, but predicting for April to be as cold as an average January is not. In fact, in my area, the coldest April on record is not even as cold as the warmest January on record.
Matthieu Guérin · Top Commenter · Gestionnaire données cliniques at BD (Becton, Dickinson and Company)Not sure that this March is better for us in Quebec... Anyway we are still stuck in a well below normal pattern most of the time. Snow cover is pretty much intact here.- Cory Morrison · Follow · Top Commenter · Filing/Labelling/General Assistant with Industrial Supply Products at Independent Distributors Inc.It appears that the extreme cold has been farther east into Quebec/Atlantic Canada this March, while in Ontario and the Midwest, the cold isn't as extreme compared to normal.
David Gerard Turco · Top Commenter · University of Rhode IslandI know that this is written to cover a very large area of real estate but for New England this very much understates the winter weather that has passed or the current and near future weather. Temps to "dip" below freezing this weekend? umm I am east of I-95 in RI and on the coast to boot and our lows will be 20 degrees. That's normal for January, not early spring. Not to mention that it takes until afternoon to get above freezing, then around 40 deg for a couple of hours before it starts to drop hence we still have about 1 foot of snow pack and Watch Hill Bay is STILL frozen, unheard of in my lifetime. Then we have below normal vs. above normal days. So far in March we've had 14 below normal and 2 above (when it rained, oh joy) and going forward by Accuweather's own forecast for RI, 39 out of the next 41 days is projected to be below average and 2 above so that's more like 20 to 1 ratio not 2 to 1 which is just a continuation of the winter. Worst stretch of weather in my 55 years.
Neven Prvinic · Follow · Top Commenter · Cleveland State UniversityIts about 80F here where in LA where i am visiting. Will worry about east when i get home next week, but from what i see, not looking good. From talking to people out here (west coast), yes their weather has been constantly warmer then average for 2 years now, and most love the feeling of that but with that being said, as miserable as it has been in the east, i think that here in the west they are having much more serious issues like how to provide millions of people with water which some areas have less than one year supply left if nothing changes, and with going into late March the hopes for any rain this 2014-15 rainy season are pretty much done. I been out here many times during March and April, and hiked the hills around LA. This time of the year those hills looked briefly lush and green, but not last year or this year, it looks brown and dry like it is August already out here.
Joshua Wade · Follow · Owensboro, KentuckyWinter Storm Thor will be far from the last major storm we're having this year. Expect an even more extreme wave of frigid air and even more vicious winter storms throughout this April. There will be an arctic assault this April, folks, this April will be infamously known as Arctic April.
Ron Hobson · Top Commenter · Controller at QUICKIE CONVENIENCE STORESgotta appreciate the irony here..... waves of cold arriving just for the weekend accompanied.
by the Friday afternoon cloud up and all day Saturday snow/ice event.... not to be outdone.
by the Monday morning Sunrise.- Joshua Wade · Follow · Owensboro, KentuckyI gotta say this again, spring will not really come until at least early-mid May. It will still be winter by April 30 and May 1 this year. Prepare for even MORE winter storms coming your way this April as well as even more extreme cold.
David Colantuono · Top Commenter · Works at UnemployedI hope you're right. I've said before that I want shorter Springs and Summers and longer Autumns and Winters. If I had it my way, the seasons would be arranged like this:
Spring... May 1st to June 20th.
Summer... June 21st to July 31st.
Autumn... August 1st to December 20th.
Winter... December 21st to April 30th.
I'm hoping that maybe...just maybe...Mother Nature will cooperate and make it feel as though the seasons were like that.
Chad E ClarkARE RAINY COLD WEATHER IS NOT OVER YET I AM SORRY TO SAY AND MORE CHANGES ON THE WAY. STAY TUNED. HERE IN NORTH CENTRAL GEORGIA.
Grant McGuire · Top Commenter · Western Connecticut State UniversityAm I insane for expecting 50s in late March?
- Tim Lynch · State University of New York at BrockportI think most of these so called meteoloists are guess less are the weather.
