Atmosphere Prepared for Powerful Storms in the Northeast and Mid Atlantic
For some in the eastern United States, the end of last week and the start of the weekend brought the first really hot, humid and sticky conditions of the season. As this taste of summer will continue to help sweat residents across the region, AccuWeather weather forecasters say it will also set the stage for something far more troublesome.
After days of warm, humid air, the atmosphere is poised to trigger a threat of severe storms early this week in parts of the mid-Atlantic and northeast.
The same storm that is about to bring volatile weather to the central United States on Sunday will move east for Monday.
“A cold front associated with this storm will deepen in the eastern states on Monday,” said AccuWeather meteorologist Rob Richards.
Once this front comes face to face with the sticky band of air already in place, strong to severe thunderstorms will quickly develop and track eastward. The timing of the strongest storms will be Monday afternoon through Monday evening, forecasters say.
A considerable portion of the East will need to keep an eye on the skies for rapidly changing conditions on Monday. Areas from northern North Carolina, through parts of Pennsylvania and New Jersey, and north to New York and much of New England all have the potential for powerful storms.
“These thunderstorms will have the potential to produce a variety of hazards including torrential downpours, hail, damaging wind gusts and even isolated tornadoes,” Richards warned.
However, AccuWeather forecasters have identified a narrower corridor where some of the most explosive storms of the day can develop.
While any location in Monday’s severe storm hazard zone can experience heavy rain, damaging wind gusts and hail, it’s in the highest hazard zone that widespread gusts of 60 to 70 mph are the more likely to occur during storms, with an AccuWeather Local StormMax&trade of 80 mph.
Winds of this magnitude can bring down trees and power lines and can also cause problems for large vehicles traveling on area roads.
The most likely arrival time for severe thunderstorms in Washington, DC, will be in the afternoon, while in Philadelphia, storms will persist until later in the afternoon. In New York, the storm threat is expected to arrive in the late afternoon or early evening. This means that for parts of the Interstate-95 corridor, some of the strongest storms are expected to arrive around evening rush hour.
After a busy weather day on Monday, Tuesday will hit an entirely different deal for much of the northeast and parts of the mid-Atlantic.
After the cold front exits much of the region on Tuesday, cooler, less humid air and windy conditions will filter through the northeast in its wake.
Beginning Tuesday and continuing into the middle of the week, many locations in the Northeastern United States will experience high temperatures reaching near to below average levels with much less humidity.
This easing of temperatures and humidity will certainly make conditions much more spring-like for a few days, rather than an early onset of summer.
AccuWeather forecasters warn that this streak of more comfortable weather may not last very long as another pattern shift looms on the horizon. At the weekend, a change in the jet stream could once again bring a sharp rise in temperatures to the region.
