Motivated by adventure, science, and awe at the power of nature, stormchasers are risking it all to get closer to tornadoes than ever before. The tornado that touched down in an open field at 6:03 P.M. on Friday, May 31 took the name of the town El Reno, but it was not a single tornado in the traditional sense, nor was it confined to one municipality.

Locally strong thunderstorms will once again take aim at the northeastern United States later today. The same storm responsible for Tuesday’s thunderstorms will bring a renewed threat of locally violent thunderstorms this afternoon and early evening. While the above areas are at greatest risk, it is not out of the question for an isolated strong thunderstorm to rattle other parts of the Northeast and mid-Atlantic into the evening. More of the thunderstorms will disrupt outdoor plans and create slower travel. Remember that as soon as thunder is heard, the risk of being struck by lightning is present. The risk of strong thunderstorms will finally wane on Thursday as drier and less

On the evening of May 31st, 1985, a devastating and deadly tornado outbreak struck the Northeastern United States and Canada. 43 tornadoes and numerous damaging thunderstorms tore across Ohio, Pennsylvania, New York, and Ontario.  This event was the deadliest tornado outbreak of the 1980’s; killing 89 people in total, injuring more than 1,000 others, and racking up more than $600 million in property damage. In fact, since May 31, 1985, only two tornado days have been deadlier in the entire United States. The thunderstorms were supported by a cold front moving east across the northeastern U.S. ahead of a low pressure system moving northeastward through the Great Lakes region.  Unseasonably warm

Storms are expected to form by around noon across western PA and NY along the front, and will develop and move relatively slowly northeastward during the afternoon, possibly reaching Vermont by evening. The primary storm mode is expected to be cellular, but small lines may eventually form with outflow mergers. Hail is expected to be a main threat, with strong wind gusts eventually as well. Long hodographs along with weak but veering winds with height in the low levels suggest a few supercells are possible. A Slight risk cannot totally be ruled out in later outlooks, although marginal moisture and instability along with the overall weak surface pattern look to temper

While Monday’s rain will be accompanied by an increase in humidity in the southern mid-Atlantic, the concern for thunderstorms to produce isolated damaging winds should mainly be confined to the South. As Monday’s rain departs, residents will want to take full advantage of the milder and drier Tuesday that will unfold. More rain spreading into the mid-Atlantic on Tuesday will indicate that the dry spell will not last long. At the same time, another band of rain and thunderstorms will rotate into the Ohio Valley and Great Lakes at midweek before slowing swinging through the rest of the Northeast Thursday into Friday. Once again, residents will be facing disruptions to travel
