Temperatures more appropriate for April will return to much of the Northeast during the middle of this week, following Memorial Day warmth.
A push of cool air is forecast to advance southward from eastern Canada and will reach New England on Tuesday, the upper mid-Atlantic during Wednesday and part of the southern mid-Atlantic by Thursday.
In the wake of the cool push, known as a back door front, temperatures will be slashed by 15 to 30 degrees F in many cases, when compared to their 80-degree-plus levels from Memorial Day.
The warm air never made it in to northern New England, but the people in Boston have already felt the cool air on Tuesday. After a high near 80 F, temperatures were hovering in the lower 50s in the city Tuesday afternoon.
By Wednesday, temperatures will be no better than the 60s around New York City and may struggle to reach 70 in Philadelphia.
On Thursday, temperatures may hold in the 60s around Washington, D.C.
Areas right along the coast will experience a breeze from the east and northeast that will add to the chill. In many cases, the cool air will be accompanied by low clouds and areas of fog.
The cool air will reach inland as well, but the change may be a bit more gradual. Cities from Albany, New York, to Scranton, Pennsylvania, and Hagerstown, Maryland, will experience the cooldown over a couple of days.
During the transition to cooler weather, moisture spilling northward from the Gulf of Mexico will lead to multiple showers and thunderstorms as millions head back to work at midweek.

After temperatures take the plunge, cool air is forecast to linger through the coming weekend in the Northeast but recover farther south in the mid-Atlantic. Highs by this coming Saturday are projected to be in the 60s in Boston, in the 70s in New York City and in near 80 F in Washington, D.C.
Indications are that the pattern of cool air making frequent visits to the Northeast may continue in the weeks ahead.
According to AccuWeather Long Range Meteorologist Mark Paquette, "Through the first part of the summer, the Northeast, especially Boston and New York City, are unlikely to have long-lasting heat."
The jet stream, a river of high-speed air well above the ground, will continue to dip southward over the Northeastern states.
"We expect only brief episodes of heat or above-average warmth through much of June and perhaps a while longer in the Northeast," Paquette said.
"The warm surges would only occur right ahead of the next push of cool air in the Northeast, but warmth would be longer lasting and more persistent farther south over the mid-Atlantic, around Washington, D.C."
During early July, high temperatures typically range from near 80 F around Boston to the middle 80s around New York City and Washington, D.C.
On a warmer note, even if cool air continues to make invasions into the region during early July, temperature dips may only translate to highs in the 70s across coastal New England and the lower 80s farther south in the mid-Atlantic with a few exceptions.
The AccuWeather long range team expects August to bring more persistent, stronger heat to the Northeast.

- Peter Kane · Top CommenterI do not think it will be like June 2009. Even though El Niño developed that year, it was cool. The cool spells in 2009 were prolonged, but this spring it was pretty rare that we had a prolonged cool spell. I know I reached 80 once in April and more and at least three times this month of May. There is still tons of unanswered information for June. That means we got to stay tuned for further updates. I am having thoughts for this coming June this week, and it is pretty challenging. June, July and August are the three months for meteorological summer.

Randy J. AndersonActually, 2013 was more strange than 2009! May 25 and May 26 felt like March! Only fracking 45 F on May 25, 2013! Record low high! Was the chilliest since May, 2007, where it was that or roughly that on May 17, 2007.- Randy J. AndersonIn 2009, the typical was a paltry 77 F, with above average monthly rain totals, with 5 inches commonly the bottom spectrum.
Damien Heppel · Top Commenter · GuildhallPeople were saying the same thing last year and we ended up with a heat wave. Summer will be hot even if it takes a bit longer to set up.
