There are signs that the prolonged stretch of cool and unsettled weather settling over the northeastern United States may give way to the warmest weather since May next week.
The storm dropping into the Northeast early this week and triggering strong thunderstorms and soaking rain into Monday will be in no hurry to leave.
Bouts of showers and thunderstorms are expected to continue to plague those with outdoor plans daily through at least Thursday in the eastern Great Lakes, mid-Atlantic and parts of the Northeast.
Umbrellas will have to be kept handy, and residents will likely not be reaching for shorts and flip-flops.
Below-normal temperatures will dominate this week, leading to an extended stretch of highs in the 60s for many communities. Boston will join the other areas of New England that will be stuck in the 50s for 2-3 days.
Highs in early June typically range from the lower 70s in eastern New England to the middle 70s in the lower Great Lakes and within a couple degrees of 80 F in the mid-Atlantic.
Temperatures should rebound back to more seasonable levels later this week as the storm should finally depart. However, another storm is likely to follow on its heels and sweep more showers and thunderstorms from the Midwest to the Northeast Friday into Saturday.
This storm is likely to not follow in the footsteps of the current storm and linger over the Midwest and Northeast into the following week.
Instead, AccuWeather Long-Range Meteorologist Max Vido expects a flip in the weather pattern to occur and open the door for summer heat to pour back in.
“From the end of May into the start of June, much of the warmth across the United States has been bottled up in the West and northern Plains,” Vido said.
“However, there is growing confidence that the heat will finally make a significant push eastward into the Midwest and Northeast early next week.”
Widespread highs in the 80s may unfold with temperatures even soaring into the 90s, especially in the mid-Atlantic and Ohio Valley.
“This will mark the most noticeable return of summerlike heat in areas east of the Mississippi River since the middle of May,” Vido said.
Higher humidity would accompany the soaring temperatures, creating even higher and more uncomfortable AccuWeather RealFeel® Temperatures.
“[The steamy air] will certainly result in more cooling demand and encourage people to finish opening up their pools,” Vido said.
Vido expects plenty of opportunities for residents to hit the pools and beaches, as well as to catch a baseball game or enjoy any other outdoor activities. However, be mindful of the water temperatures of the ocean and local streams and rivers.
The waters along the New England coast, most of the Great Lakes and many streams are still too cold to enter.
The main risk for thunderstorms early next week amid the heat will be over the Appalachian Mountains.
"While mostly dry conditions will likely accompany the heat, this pattern favors thunderstorm development over the mountains during the afternoon," Vido said.
The timing of the next storm tracking eastward from the northern Plains will determine whether the surging heat will only last a couple of days or will persist into the middle of the week.
