Yet another burst of severe thunderstorms to rip across the Northeast
“The Northeast has become a hotbed for tornado activity in recent weeks and there is at least some risk for a quick spin-up twister once again in parts of New England during the day on Friday,” one AccuWeather expert said.
Locally severe weather shifts into the northeastern United States through the end of this week as a cool front sweeps through the region, AccuWeather meteorologists caution.
As a massive dome of heat sets up over the Great Plains and Mississippi Valley in the coming days, bursts of cool air from central Canada will drop across the northeastern corner of the U.S. The waves of cool air will help to trim back temperatures and humidity in the region. Showers and thunderstorms that will be triggered along the leading edge of cool air will signal the changes.
"Yet another round of drenching and gusty thunderstorms are in store across the Northeast into Friday evening as a powerful cool front sweeps through the region," AccuWeather Meteorologist Brandon Buckingham said.
Some of the strongest storms will pack damaging wind gusts and hail.
Thunderstorms will ramp up in intensity through the day on Friday in eastern New York state and New England due to daytime heating ahead of the cool front.
"With an abundance of moisture in place ahead of the approaching front into Friday evening, the risk of flash flooding will increase in many of the same places that have been hit with repeated rounds of heavy rain this summer," Buckingham said.
Since June 1, many locations over the central Appalachians and New England have received one-and-a-half to two times their historical average rainfall. Much of that rain fell over a few weeks during the middle of the summer and triggered deadly or damaging flash flooding in some communities.
Along with the potential for storms with flooding downpours, high winds and hail, a couple of tornadoes cannot be ruled out.
"The Northeast has become a hotbed for tornado activity in recent weeks, and there is at least some risk for a quick spin-up twister once again in parts of New England during the day on Friday," Buckingham said during an interview on Thursday.
Just prior to 9 a.m. local time on Friday, a radar indicated tornado was traveling northeastward across Rhode Island.
There have been close to a dozen reports of tornadoes from Pennsylvania to Massachusetts since the start of August.
The risk of thunderstorms on Friday will be limited to the morning hours in New York City and Philadelphia. Any thunderstorm that passes through the Washington, D.C., area will likely depart by early Friday.
Thunderstorms around Boston and eastern New England during the daylight hours on Friday will swing offshore at night.
After a cooler and less humid Saturday, warmth and humidity levels will begin to climb in the region later this weekend.
Wildfire smoke from blazes in Canada may cause the sky to appear to be hazy at times this weekend.
