At least half a dozen tornadoes were probably fired Tuesday night in different parts of Pennsylvania and the northeast. The tornadoes fell when multiple violent storms hit the area. Strong winds up to 100 km / h and the size of a limes also accompanied the mixture of broken lines and powerful supercell storms.
It was an unusually volatile mass of air during the late season of the season. The results bear witness to this.
The epicenter of this event was the state of Keystone, which had once five Active tornado warnings have splashed across the Commonwealth. While the likelihood of strong tornadoes was initially referred to as "low", the event was probably surpassed as it spread across Pennsylvania and parts of New York, New Jersey and southern New -England.

What could have been the wild card was the environment of "boom or recession" in place. While instability was low to modest, wind shear in the atmosphere was virtually irrelevant, especially for the time of year. The winds swept rapidly with height, producing impressive atmospheric effects, even by the standards of the Great Plains.
The result? Rotation of storms. Many of them – tornado falls.
A dozen well-structured supercells or rotating storms crossed the east and southeast in the afternoon and evening. The action began near Erie, Pennsylvania, and ended in Long Island after dark.
The dam's worst tornado landed in Conneautville, a rural community in Crawford County, northwestern Pennsylvania. With a preliminary rating of EF2, or "strong", the vortex crashed into the area under winds estimated at 115 mph. He was responsible for ripping off the roof of a retirement home shortly after 2:30 pm.
Officially, two other tornadoes have been confirmed so far – one near Stony Point, NY, and the other on Long Island. However, additional tornado confirmations are likely, and this number will likely increase by at least a little more as investigations continue.
National Meteorological Service investigations will also determine whether a tornado or microburst has caused each damage, as well as the strength / width of the wind storms responsible.
Joe Murgo, WTAJ-TV's chief meteorologist in Altoona, Pennsylvania, called the day "amazing day".
Thirty-eight tornado warnings were issued by the NWS in the 500-mile impact zone of the storm system. When all figures are calculated, it seems likely that this will be one of the busiest days of severe weather at the end of the season in modern history for the region.
"[This was the] most tornado warnings in my display area for almost 18 years that I am at the station, "wrote Murgo. "The most incredible thing is that it happened in October!" Murgo provided nonstop coverage starting at 16:40 and continuing until 19:00, when the last warning will expire in its viewing area. .
The EF2 tornado in Pennsylvania is the last of this year since December 2006 and the first in October or later since 2012. Such a dam is remarkable at any time of the year in the region. late in the year by the total number.
After the disappearance of the main storm eruption, a few isolated cells erupted just outside, near the Three States of New York, New Jersey and Connecticut.
In Connecticut, Connecticut, a particularly courageous group has developed a "donut hole" type signature, also called a weak echo zone or BWER. This indicates that strong upstream winds prevented rain from falling in this area, also associated with significant rotation and a possible tornado.
The same cell crossed the Long Island Strait and headed towards Long Island, creating several small circulations that could have dropped tornadoes. At least one tornado was confirmed by the NWS this morning, the most eastern tornado that took place on Long Island was reported so late in the year in modern history.
It was not just the tornadoes that Mother Nature had in the arsenal during this event.
Hail, the size of a golf ball, hit places like Lamar, in Clinton County, Pennsylvania. Five dozen gales have also been reported.
Once the sun went down and the heat was lost during the day, most storms merged to form lines that produced a prolific light show. More than 30,000 Flashes of cloud on the ground lit up the northeast, sometimes making the clouds of the storm flash, seemingly nonstop like a candle.
