As the unofficial start to summer approaches next week, the longest stretch of warmth so far this year will surge into the northeastern United States.
The warm surge will yield multiple days of highs in the 80s across most of the Northeast and mid-Atlantic, but not until after the storm responsible for this dreary weekend departs.
"Summerlike warmth will gradually move into the Northeast next week," AccuWeather Meteorologist Steve Travis said, "however, it will be delayed at the start of the week by a slow-moving storm that will keep cooler air entrenched along the Eastern Seaboard."
Temperatures will be stuck in the 60s along the Northeast coast, including Boston, on Monday and then in many New England communities on Tuesday.
Temperatures will rebound away from Sunday's widespread highs in the 60s elsewhere in the Northeast early next week but will still be held near to below normal from New York City to Washington, D.C., to Richmond, Virginia, on Monday.
Showers and thunderstorms will also accompany the storm, generally focusing on the mid-Atlantic on Monday and then New England on Tuesday.
While the storm holds down temperatures across parts of the Northeast, warmth will surge northward over it from the midwestern U.S. to the Canadian provinces of Quebec and Labrador.
Quebec City and Montreal will be warmer than Washington, D.C., and Philadelphia on Monday. Boston will then be cooler than Goose Bay that is located about 900 miles to the north in Labrador on Tuesday.
As the storm departs, the door will then be open for the summer warmth to spread into the Northeast at midweek.
"Winds will shift out of the southwest on Wednesday, which will transport much warmer air into the region, sending high temperatures in the 80s for many areas through the end of the week," Travis said.
The second half of next week will bring the longest stretch of warmth to the Northeast and mid-Atlantic and could rival the days from earlier this spring as the warmest so far this year.
"Temperatures will even approach 90 F in the mid-Atlantic later next week," AccuWeather Meteorologist Ed Vallee said.
A cold front will attempt to put the brakes on the warming trend in northern New England on Thursday. Even if the front is successful, warmer air will quickly return by the holiday weekend.
Midweek will likely present the best opportunity for those looking to get outdoors and take advantage of the warmth. Aside from the potential for a shower in northern New England, dry weather will dominate and humidity levels will still be low.
Residents will be able to resume yard or field work that had to be put on hold by the weekend and early week storminess.
Humidity levels, as well as showers and thunderstorms will increase later in the week, resulting in even higher AccuWeather RealFeel® temperatures and a greater chance of disruptions to outdoor plans.
While actual temperatures may stop short of doing so, RealFeels could eclipse the 90-degree mark. That is especially true in the mid-Atlantic.
The impending warmth and humidity could put a strain on those engaging in strenuous activities, especially since this May has been cool and residents have not yet gotten accustomed to summer warmth.
The warm, humid and unsettled weather pattern will persist into the long holiday weekend, but some cooling may come to northern New England and the Great Lakes for Memorial Day.
"By the beginning of June, temperatures will likely return to normal levels, especially across the Great Lakes and New England," Vallee said.
