Severe storms to take aim at the East Coast

A strengthening storm has begun to unleash major impacts across much of the eastern half of the country early this week.
Into Monday night, this storm system will dump snow over the Midwest and bring drenching rain to the Northeast. While that occurs, this system will also trigger the threat for severe weather to portions of the East Coast.

As this system moved northward over the interior South, it tapped into plenty of atmospheric fuel to deliver drenching rain and even a few severe thunderstorms from the Gulf Coast to the interior Southeast into early Monday. One such storm was reported to have caused some structural damage in addition to taking down trees and power lines in northern Florida's Madison County.

The threat for severe thunderstorms has shifted much farther to the east and north as of Monday afternoon.
"Into Monday evening, an unseasonably moist air mass will be pulled northward along the mid-Atlantic Interstate-95 corridor and into southern New England," AccuWeather Senior Meteorologist Dan Pydynowski said.
"Strong-to-severe thunderstorms may track through cities like Philadelphia, New York City and even Boston into Monday evening," Pydynowski added.
Other cities that may end up in the direct path of these damaging storms include Norfolk, Virginia; Washington, D.C.; Dover, Delaware; Ocean City, New Jersey; and Allentown, Pennsylvania.
Damage was reported near Montgomeryville, Pennsylvania, on Monday evening after a tornado-warned thunderstorm tracked through the area. It is unclear if a tornado touched down, but extensive tree damage was reported in the area.

Very strong winds located higher in the atmosphere, just above the surface will be howling across much of the northeastern quarter of the United States into Monday night. Any stronger storm that develops will not have to work too hard to be able to tap into strong winds aloft and bring them crashing down to the surface.
Into Monday evening, the most prevalent threat with any strong thunderstorms that rumble to life will be damaging wind gusts with an AccuWeather Local StormMax™ of 80 mph. The strong winds can occur even without any thunder or lightning.
Winds of this magnitude will be strong enough to damage trees and even take down some power lines, leading to sporadic power outages. Heavy downpours can also occur in strong storms and may lead to localized flash flooding issues.
However, for some across the eastern U.S. into Monday evening, an additional threat may be tacked on to the list -- isolated tornadoes.
"Isolated tornadoes cannot be ruled out across parts of the mid-Atlantic given the setup," Pydynowski cautioned.
Tornadoes have impacted portions of the mid-Atlantic in November in recent history. On Nov. 2, 2018, at least three tornadoes were confirmed to have inflicted damage on portions of Virginia and Maryland. One of these tornadoes was responsible for two deaths and an additional injury in Baltimore, Maryland.
Despite the fact that Monday is the last day of November, residents across the East will need to keep an eye to the sky for rapidly changing conditions.
