After a surge of warmth, storms will ease heat and humidity levels across the Great Lakes and northeastern United States prior to the middle of the week.
An advancing cool front is expected to truncate the resurgence of warmth and humidity. Thunderstorms will erupt along the front.
"Some of the storms that form along the front can become heavy and gusty at the local level from some of the Ohio Valley states to the St. Lawrence Valley along the U.S. and Canada border," according to AccuWeather Senior Meteorologist Alex Sosnowski.

"With the risk of locally gusty storms in mind, the vast majority of the storms will not be severe, and some locations may not even have thunder and lightning with the passage of the cool front," Sosnowski said.
Cities that could be impacted by locally damaging winds, hail and torrential downpours include Indianapolis; Cleveland; Detroit; Erie, Pennsylvania; Buffalo and Syracuse, New York; and Quebec City, Montreal and Toronto.

Storms are expected to lose some of their punch during the overnight hours but could hold together long enough to make for a wet, slower-than-normal commute from Boston to Washington, D.C., on Tuesday morning.
A few storms could be reinvigorated and become locally strong and gusty across portions of Virginia, eastern Kentucky and southern portions of West Virginia, Maryland and Delaware during Tuesday afternoon.

Cooler, drier air will spill southeastward in the wake of these storms.
Temperatures will be slashed 10-15 degrees Fahrenheit across part of the region on Tuesday.
Locations across the northern tier will feel the brunt of the cooling from this system.
"Areas from Michigan eastward to New York and New England will experience the most noticeable drop in temperatures," according to AccuWeather Senior Meteorologist Matt Rinde.
Highs in the upper 80s and low 90s to start the workweek will be replaced with highs in the upper 70s and low 80s on Tuesday. Further cooling may take place on Wednesday.

Humidity levels will lower.
"These drier conditions will make it much more pleasant to get outdoor work done," Rinde said.
While temperatures will not drop as drastically across the northeastern I-95 corridor, much drier air will reach the Eastern Seaboard by Wednesday.
Lower humidity levels will keep AccuWeather RealFeel® Temperatures within a few degrees of the actual high.
Wednesday will offer a great opportunity to get outdoors as dry weather is expected to prevail for most of the region. Spotty showers could dampen part of the day in New England.
The threat for drenching rain and severe thunderstorms will return to parts of the Midwest on Wednesday and a portion of the Northeast on Thursday.
