Bout of cooler air to interrupt summerlike warmth across northeastern US

Temperatures and humidity levels will throttle back as dry air expands southward in the northeastern United States through the middle of the week.

A plume of tropical moisture, associated in part from Tropical Rainstorm Bonnie, will be shunted out to sea on Tuesday.

"While Tuesday will still be rather warm, humidity levels will lower as the day progresses. Highs will be well into the 80s F on Tuesday," according to AccuWeather Meteorologist Steve Travis. "Clearing on Tuesday will make for an ideal day at the pool or on the beach."

The stage will be set for better sleeping conditions, perhaps without the aid of air conditioners, by Tuesday night. Temperatures will drop into the lower to middle 60s in the major metro areas of the Interstate 95 corridor from southern New England to the mid-Atlantic.

While temperatures are forecast to average a bit above normal over much of the mid-Atlantic Wednesday and Thursday, the air will be significantly cooler and less humid, when compared to Memorial Day weekend.

AccuWeather RealFeel® Temperatures will be 15-20 degrees lower, when compared to last Saturday. RealFeel Temperatures surged well into the 90s to near 100 in some urban areas.

Highs will range from the 70s over the central Appalachians to near 80 in the I-95 corridor at midweek.

"A more significant cooldown is in store for the eastern coast of New England with highs mainly in the 60s during Wednesday and Thursday," according to AccuWeather Meteorologist Edward Vallee.

Highs will be in the 70s along the southern New England coast at midweek.

An exception to the cooler, drier and less humid conditions will be southern Virginia, where tropical air and downpours may linger longer and return quickly.

This week started with and will likely end with downpours along the I-95 corridor, AccuWeather Senior Meteorologist John Gresiak stated.

"A storm system with the potential for severe weather will reach the Northeast toward the end of the week with showers and thunderstorms," Gresiak said.

The next chance of rain will come on Thursday in the swath from Charleston, West Virginia, Pittsburgh and Buffalo, New York. Rain will be possible in the corridor from Washington, D.C., to Baltimore, Philadelphia, New York City and Boston on Friday.

While some of the thunderstorms could be locally heavy, the storms will likely lose intensity after departing the Midwest.
