Dangerous storms threaten to ruin outdoor plans and wreak havoc on the evening commute across the eastern Great Lakes and Northeast.

Very hot and muggy air will help to fuel the thunderstorms with temperatures climbing well into the 80s and 90s.

At least a couple of zones of nasty thunderstorms are expected to develop with the heating of the day encompassing areas from lower Michigan, Ohio, Pennsylvania and upstate New York to Virginia, the Delmarva, coastal New York, New Jersey and part of New England.

Some of the storms will become severe, providing the threat for damaging wind gusts and hail. In a couple of instances a tornado can be produced by the strongest storms.

Detroit, Cleveland, Buffalo, Pittsburgh, Philadelphia and perhaps New York City could all be in the path of the damaging storms.

The strongest storms can produce wind gusts to 65 mph which is more than enough to knock down tree limbs and power poles.

While damaging winds appear to be the biggest threat, there can be large hail and flash flooding.

If threatening weather approaches, be sure to have a secure indoor location to move to.

Heed any watches or warnings and as always, check back with the AccuWeather.com Severe Weather Center.

Strong thunderstorms will shift farther east Monday evening, bringing a damaging wind threat to Rochester, Burlington, and perhaps Montreal. However, as the night progresses, thunderstorms will lose their intensity thanks to loss of daytime heating.

This Day In Weather History

New York/MA (1819)
Two simultaneous cloudbursts, 45 miles apart; A bucket survey claimed 15" of rain fell at Catskill, NY. Highways were completely washed out. One washout started west of the old Albany Post Road and spread eastward across the road until it was 190 feet wide and 80 feet deep in a distance of 160 paces. At Westfield Valley, "suddenly the windows of heaven seemed to have been opened and the rain fell in such torrents that in less than 5 hours, Westfield River rose at least 20 feet above its usual height at low water. The river overflowed its banks with great rapidity and violence, sweeping away every bridge, fence and building which opposed its current."

Pittsburgh, PA (1872)
Cloudburst of 30 minutes followed by a flash flood. Over 133 people drowned on the north side of Butcher Run and Wood's Run.
