Wet Wednesday in Store For Boston, Albany

Travel delays and cancellations will be a common theme across New England on Wednesday and into Thursday as a potent system moves into the region.

Heavy rain and thunderstorms will target folks from New York to Maine, and into Ontario and Quebec.

"Flash flooding will be the biggest threat with these showers and storms," said AccuWeather Storm Warning Meteorologist Phil Warren.

Cities at risk for heavy rain and flooding include Albany, New York; Burlington, Vermont; Hartford, Connecticut; Providence, Rhode Island; Springfield, Massachusetts; Boston, Massachusetts; Concord, New Hampshire; Portland, Maine; Montreal, Quebec; and Quebec City, Quebec.

"Rainfall totals of 1 to 2 inches will be common across many locations," added Warren. "Higher amounts of up to 4 inches will not be out of the question either for some areas."

With abundant moisture to tap into, these storms will likely bring torrential downpours. Rainfall rates could approach 1 to 2 inches per hour in some of the heaviest storms.

With these kind of rainfall rates, some roads could turn into rivers or lakes and motorists could be faced with delays.

Those caught out in a blinding downpour are urged to reduce speed, turn on their headlights, and to turn around or find an alternative route if high water lies ahead.

Conditions will gradually improve for New York City through the day.

Some rain may be around early this morning but the heaviest will be already off to the north and east," said AccuWeather Senior Meteorologist Carl Babinski.

The soaking rain will instead target New England, including Boston.

"The threat for heavy rain and flooding will be longer lasting in Boston and across southern New England Wednesday," added Babinski.

Those living in Quebec City, Bangor, or anywhere in between, will likely see the heaviest rain arrive on Wednesday night and into Thursday.

Umbrellas and rain jackets will certainly be needed for anybody heading outside.

This potent area of low pressure has had a history of producing flash flooding. Detroit was hit with heavy rain on Monday, setting a new record for the wettest day in August. Several major roadways, including I-94, was shut down due to several feet of standing water.

Baltimore, Maryland and Millville, New Jersey, were drenched with some of the heaviest rain on Tuesday. Millville recorded nearly 9 inches of rain while rain gauges in Baltimore read just over 6 inches. The outer-loop of I-695 was closed due to high water.

A sinkhole opened up near Pittsburgh, Pennsylvania, swallowing a car and a woman inside. She was able to escape without injury. Several wind and hail reports were observed near the city as well.

The severe threat will be lower on Wednesday, although a few reports of gusty winds and hail will be possible across southern New England.

Unseasonably cool air will filter in behind the area of low pressure for the end of the week. Interior portions of the Northeast may be dampened with a shower while coastal locations will turn dry with some sunshine.

The cool weather will likely not last. AccuWeather.com Meteorologists are predicting a warm-up in the next week or two.
