Memorial Day marks the unofficial start to summer, but the summer warmth set to dominate the Northeast next week will lack staying power.
The last week of May will feel like summer across the Northeast.
After warmth surges into the mid-Atlantic for Memorial Day, warm and humid air from the South and Ohio Valley will flood the entire Northeast by the middle of next week.
Many locations in the Northeast will experience consecutive days with highs near or above 80 F next week. Philadelphia and Baltimore will be among the communities along the mid-Atlantic's I-95 corridor that could record the first 90-degree day of the year.
The humid air will create even higher AccuWeather RealFeel® temperatures.
Those looking to escape the warmth may want to plan a trip to the southwest-facing beaches of the Northeast. Winds flowing off the cooler ocean may limit the amount of warming.
Daily showers and thunderstorms will dot the Northeast amid the steamy air with the afternoon and evening hours being the most active. While creating disruptions for outdoor plans, the rainfall will be beneficial.
The United States Drought Monitor reported on May 21 that nearly 23 percent of the Northeast is in the midst of a moderate drought. The greatest concentration of this status is centered on southern and central New England and southeastern New York.
While summer warmth will dominate next week, AccuWeather Expert Long-Range Forecaster Paul Pastelok stated that it will not have staying power into June.
"The warmth will back off [for the last weekend of May]," Pastelok said.
The cooler air due to arrive that weekend will pale in comparison to what will kick off this Memorial Day holiday weekend. Temperatures will return closer to normal for May 30-31 with less communities facing a frost/freeze concern.
"If it clears out during the last weekend of May, there could be another frost across the interior of New York to northern New England," added Pastelok. "However, that frost threat does not look to be as widespread as this Friday night [May 22]."
This Friday night should also be the last threat of a frost and freeze from Pennsylvania southward, according to Pastelok.
The Northeast will remain the battleground of cool shots and surging summer warmth into early June.
Due to the atmosphere naturally warming heading into summer, "The one thing to note is that each cooler air mass will not be as cool as the previous," Pastelok said.
As the cool shots wane, the source region of warmth for the Northeast this summer--the northern Plains--will also be heating up and setting the stage for the above-normal temperatures and drier conditions that Pastelok expects will dominate the Northeast this summer.
