The visible satellite loop above shows the development and explosive growth of thunderstorms across southern Ontario, Ohio, western Pennsylvania and western New York on the afternoon of May 31, This two day series of Daily Weather Maps (courtesy NOAA/NWS) shows the eastward progression of the cold front; from near Chicago on Friday morning May 31, Precipitation looks like a hook on the radar returns; showing. Please try another search. Nothing like it has occurred so far removed from the prime tornado zones since, and the Philadelphia region in all likelihood would not see anything similar, Brooks said. SOUTHERN LAKE ONTARIO Thomas P. Grazulis Ted Fujita), or meteorological research institutions (i.e. The combination of moisture, instability, lift, and wind shear were present across a large area of the northeastern U.S. on May 31st. Twenty-one tornadoes tracked across Northeast Ohio and Northwest Pennsylvania during the evening of May 31st. Nine people were killed in the business district of Niles. As we travelled along the road, we broke out of the tree cover and came across the Moshannon State Park F4 tornado path that was over one mile wide. Nineteen buildings on two farms reportedly "vanished". At the same time, conditions in the upper atmosphere continued to become more favorable for an outbreak of severe weather. Cars flipped around every which way. Everybody should take cover! Can Pennsylvania get tornadoes? - Think Real State That evening while watching television (Superman IIto be precise; back in those "old days," the networks aired movies on Fridaynights), a crawl ran across the bottom of the screen that listed several counties in the viewing area that were in a tornado watch (these would have been counties in the northern part of the Harrisburg viewing area). I constantly post weather tips on my FB page and am a certified NWS spotter. Questions? Seconds later the tornado touched down just beyond the house and tore a path to the next town, destroying homes and blowing a train off of the railroad tracks.

As the tornado continued east along its 45 mile path of destruction, it crossed the state line and slammed into the community of Wheatland located in Mercer County, Pennsylvania. The main issue was the timing and location of the primeingredients. 1985: A Tornado Goes Through the Neighborhood! **(With - YouTube Worldwide, a total of 67 tornadoes have been officially rated F5/EF5: 59 in the United States, two each in France and Germany, and one each in Argentina, Australia, Canada, and Italy. This was mine. An EF5 tornado is the strongest designation a tornado can receive. Preparedness I drew on that experience numerous times in the decades ahead, mostly in storm-prone central Illinois. Stories of heroism also emerged. Soundings are created by plotting the data reported by weather balloons that are launched by the NWS each day all across the country. However, much changed during the evening hours. Kane, PA F4 Tornado May 31, 1985 Highways & Hailstones First Amendment: Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances. In its post-storm report, the National Oceanic and Atmospheric Administration stated soberly: Perhaps the lesson to be learned from the 1985 outbreak is that under the proper atmospheric conditions, major tornadoes can occur irrespective of the location or terrain.". EMA Response & Technology of the Day, The 1985 Tornado Outbreak Revisited, Forecast At bit later, storm development southwest of the original tornado watch prompted the issuance of another that included much of the remainder of Ohio; a third watch was issued later in the shift into eastern Pennsylvania. The residents of Ohio and Pennsylvania will long remember May 31st, 1985. An embedded "ball image indicated that it had ingested massive quantities of debris, recalled Greg Forbes, at the time a Penn State professor who later would become one of the countrys most visible severe-storm specialists. It wasn't until the following day when I surveyed the damage with Greg Forbes and others that I realized that I was probably within about a mile of the giant tornado. Natural Disaster Survey Report to the Administrator of NOAA. Thank you. At the time of the call, I did not know who Greg was, or that he had been one of the few PhD candidates of Dr Ted Fujita. Resulting in 34 deaths, the Xenia tornado was the deadliest of all tornadoes from this outbreak and remains among the top 10 costliest U.S. tornadoes on record (approximately $250 million in 1974). But the physical processes responsible for the deviant motion of supercells relative to the mean flow --- and their sustenance in relatively "hostile" thermodynamic environments such as that present (at least the surface) over north central Pennsylvania --- were not widely known. Climate Prediction Center This sounding is quite impressive for a late-May morning and quite favorable for tornadoes. The initial thunderstorms in the state occurred between 3 and 4 p.m. near Cleveland. After graduating from PSU, I attended the University of Oklahoma for graduate school (1996-2000), where I studied tornadogenesis, and since 2001, I've been back at PSU as a professor now making a living studying tornado formation. Rescuers from the Shenango Valley were dispatched north. Farms "entirely vanished," with debris carried for miles. Jefferson County also indicated no reports of severe weather until golf ball sized hail was reported in Brookville as the storm rapidly exited Jefferson County and moved into southern Elk County about 7:20 PM. That day, that week forever etched in my mind. Tornadoes in Pennsylvania | William Chittester This flight was about an hour long and again the tornados path was easy to see from the air. They made an about-face when reports of a second twister came in less than two hours later. Tornado watches in Philadelphia are new to this region. We were spared but others were not so lucky. I worked the 4pm-midnight shift on May 31st. The second F4 that went through Corry in Eastern Erie County touched down at 5:25 PM. This tornado took nearly the same path as the next one, below. During that time period I have gotten to see plenty of severe weather, both on radar and in person. Atlantic was just about totally wiped out. The tornado moved across the northwestern tip of Crawford County and then entered Erie County near Pennside. All NOAA, A slow-moving storm system will continue rounds of low elevation rain showers and higher elevation rain/snow over the Ohio Valley and Northeast through midweek. Most of Europe, on the other hand, uses the TORRO tornado intensity scale (or T-Scale), which ranks tornado intensity between T0 and T11; F5/EF5 tornadoes are approximately equivalent to T10 to T11 on the T-Scale. This day remains the deadliest tornado outbreak ever documented in Pennsylvania. We knew we had windsbacking with height from southeast to southwest aloft and increasing with height. Wereturned home that night, and I told my parents that I had made a decision that is still with metoday: I wanted to chase tornadoes. We pondered these ideas as we briefed the incomingmidnightshift. For much of the area, this Friday was the last day of the school year, but by early afternoon it felt more like the middle of July than the end of May. I stayed two hours beyond my normal shift, through peak heating, andthen went home. Created by: Maria Chairmonte December 15, 2022 Retrieved from: https://www.weather.gov/media/cle/Wx_Events/85outbreak/1985%20Tornado%20Final%5B1%5D.pdfNOAA National Centers for Environmental Information (2019). I remember about 4:00-4:30 in the afternoon a few coming into the Penn State weather station to check on whether the anticipated severe weather outbreak had gotten going. In addition to the Newton Falls-Niles tornado, other somewhat weaker tornadoes affected the counties in Northeast Ohio. We flew over Kane which was directly hit. In fact, since May 31, 1985, only two tornado days have been deadlier in the entire United States. This tornado is officially rated F4; however, the Polish Weather Service estimated winds at 246 to 324mph (396 to 521km/h), potentially ranking it as an F5. This is a dynamic list and may never be able to satisfy particular standards for completeness. I can vaguely remember the unusual heat and humidity that was around for that time of the year. The tornado destroyed nearly the entire town of Wheatland, and seven more people were killed. On June 3rd, the Federal Government declared a state of emergency for the state of Pennsylvania. Hundreds were left homeless. It brought home just how quickly and tragically a tornado can change lives. Never again will I be caught off-guard. Just before dawn on May 31, 1985, a warm front lifted across the Ohio-Pennsylvania border and temperatures soared into the 80s in Cleveland and Erie, according to the National Weather Service account. Established in 2009. In 1987 we went on a family picnic with him to Parker Dam and he took me on a little road trip through Moshannon State Park. In Ohio, this was the worst event since the April 3-4th, 1974 outbreak that killed 37 in Xenia (NWS, 2019). US Dept of Commerce Unseasonably warm and humid air moved northward into Pennsylvania and much of the eastern U.S. ahead of the cold front, setting the stage for strong thunderstorms and tornadoes. Of the 59 tornadoes in the United States, 50 are officially rated F5 on the original Fujita scale (with dates of occurrence between May 11, 1953, and May 3, 1999), and nine are officially rated EF5 on the Enhanced Fujita scale (with dates of occurrence between May 4, 2007, and May 20, 2013). A car was thrown a block and a half. We'd love to hear it! This was my first severe weather shift as a lead forecaster. The low tracked across the northern Great Lakes during the afternoon, while the cold front progressed eastward across Indiana and western Ohio. The Last EF5 Tornado Struck Over 8 Years Ago And That's the Longest Tornadoes are among the most violent known meteorological phenomena. "TORNADO!" The true enormity of the31 Mayevent would not, however, become apparent to me until the following day when I awoke to radio news accounts from the devastated region. I had just been promoted to lead forecaster in March of 1985. Thinking that someone might need help, we circled over the area for several minutes trying to locate someone but were never able to find anyone. Quoting the original survey report produced by NOAA in 1985, perhaps the lesson to be learned from the 1985 outbreak is that under the proper atmospheric conditions, major tornadoes can occur irrespective of the location or terrain. Most of these tornadoes occurred prior to 1950, before tornadoes were rated according to standardized damage assessments, and their unofficial classifications as F5/EF5/T10+ or equivalent have been made in retrospect, largely on the basis of photographic analysis and eyewitness accounts. After issuing the early Convective Outlook, I went home to bed. Cochranton, Cherry Tree, Cooperstown and Tionesta were also hard hit. Many homes in town were destroyed, some of which were swept away with very little debris left. A barn was destroyed and trees still standing were denuded, a flatbed truck rolled over, a car was torn apart with only the frame remaining nearby. The second F4 to affect Erie County touched down between Wattsburg and Corry in eastern Erie County. This might have been the same tornado that struck north of Tionesta but I am not sure. I attended PSU for a B.S. 5:45 pm EDT - Tornado Warning It was extremely hot and muggy. Hailstones the size of golf balls damaged countless vehicles in areas completely untouched by the twisters. These indications can come from the United States government, Doppler on Wheels, tornado experts (i.e. But the state also experiences tornadoes of EF-3 category and above.

National Weather Service An additional component to the magnitude of the thunderstorms on May 31st was the presence of a significant elevated mixed layer (EML) , a common supporting ingredient in severe weather across the northeastern U.S. (Banacos and Ekster). On May 31st, 1985 I was a wide eyed 14 year old boy living in Punxsutawney, PA. At that time I was still trying to figure out what I wanted to do when I got out of High School and had to go to college. We were aware that thunderstorms already were occurring in Ontario as we arrived for work on the 31st, although I do not think we knew that they already had produced tornadoes. He said researchers have seen a change in tornado variability. At 500 mb, a negatively tilted trough was positioned over the Midwest (Figure 3) with strong westerly winds in excess of 80 knots directly in front of the trough. There were so many warnings the teletype got backed up a good 10-15 minutes. In spring 1993 I had the opportunity to drive through the path of the Moshannon tornado with fellow Penn Stater and NWS forecaster Bill Gartner. Weather Link copied to clipboard A tornado outbreak killed 64 people in Pennsylvania 35 years ago. This was the first time I'd ever heard/seen the term "tornado watch," and I distinctly recall asking my parents what it meant (I think they gave a decent answer, though some of the details now escape me). 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. The wind took him away, but the youngsters were spared. I expected to meet a PSP helicopter but instead an Army or National Guard helicopter arrived. Three farms were obliterated, with all buildings and several inches of topsoil swept away. A well-built home shouldn't be at risk, but a tornado of this intensity might be capable of moving a mobile home or caravan. [6] The Enhanced Fujita scale is used predominantly in North America. Part II: Comparison of Observed Damage and Radar-Derived Winds in the Tornadoes", "Tuesday's Tornado Near Bennington, Kansas, a Dj Vu From a Weird Tornado Path 5 Years Ago", "Why was El Reno, Oklahoma tornado downgraded to EF3? Eight years after the event, the path of the nearly mile-wide monster storm remained nearly devoid of trees --- in stark contrast to the richly green forest surrounding it. Following are several images of what the thunderstorms looked like to meteorologist on radar. This tornado impacted several farms, including one where a "fine new residence" was swept completely away. Considered to be a probable F5 by Grazulis. Note the dewpoint temperature of 71 at Bradford, PA! Sorry, the location you searched for was not found. At 4:20 PM SELS issued the tornado watch 211, valid at 5pm. After 8 PM, the outflow from the Big Beaver storm initiated a new storm that produced an F1 short track tornado in East Sparta, OH just west of the Pittsburgh WSR-57 radar. National Oceanic and Atmospheric Administration An F5 tornado rated years ago is still an F5, but the wind speed associated with the tornado may have been somewhat less than previously estimated. Tales of being in their homes or yards and having little time to react. Figure 7 depicts a modified sounding depicting the CAPE at Pittsburgh, PA at 7:00 pm. At any rate, I immediately decided I wanted to be a meteorologist. State College, PA328 Innovation Blvd, Suite 330State College, PA 16803(814)954-6440Comments? Many other hospital workers and I went in, and we opened a floor to take in victims. W. VA Twenty-one tornadoes tracked across Northeast Ohio and Northwest Pennsylvania during the evening of May 31st. Homes and entire farms were swept away, and cars were carried for hundreds of yards. After leaving Kane we flew westerly over another tornados path which hit the Tionesta Scenic and Natural Area and the Hickory Creek Wilderness Area, both of which are located in the Allegheny National Forest. (BACK TO TOP), Beaver County Times - Collection of 30th Anniversary Articles, Cleveland Plain Dealer - 25th Anniversary, Pittsburgh Post Gazette - 20th Anniversary, Tornado Watch Number 211 by John G.

Keep in mind that this F4 was on the ground for over 60 miles. Click on a tornado name in the table below to view more details about each tornado. When I got home, I sat down for some dinner and to watch a video I had rented for a Friday night movie. So many heroes. Atlantic was thoroughly devastated. And it is hard to tell the difference among them all, but I would say in terms of destruction, just total devastation, this is the worst I have seen." . EMLs act as a lid in the atmosphere, stopping convection from occurring unless the lid can be removed or sufficient lift is present. There was no grass. I was to work from the church. The same supercell dropped another tornado right across the state line in Pennsylvania 15 minutes later and killed 9 people in Big Beaver, Pennsylvania. For a couple of days leading up to May 31st there was talk in the Penn State weather station that the weather pattern was taking shape for a severe weather outbreak over Ohio and Pennsylvania. According to the NWS Cleveland, OH (2019), research has shown that this signature on a Skew-T is a good indicator of significant severe weather. I will never forget the young man who was at his grandparents farmhouse with his fianc (he was to be married the next day). The "single" deadliest tornado in U.S. history was the famous Tri-State Tornado of March 25, 1925. Nine years later, I left home to pursue a degree in meteorology from the University ofOklahoma. One station I was updating was WKZA in Kane, a daytime only AM station (it no longer exists). The former Peter J. Schmitt Co. and Golden Dawn stores donated 100 cases each of paper towels, personal care items, diapers and canned vegetables. 34 years ago today in my hometown of Niles, Ohio, this F5 tornado killed nine people. pic.twitter.com/61pK1ZSbT6. We suspected the Canadianstorms were bad, but had no way of verifying. This list includes tornadoes previously rated F5 or EF5 by the National Weather Service as well as tornadoes rated F5/EF5 by other branches of the United States government, tornado experts (i.e. This interactive map, which contains data from January 1950 to December 31, 2022, pinpoints where a cyclone touched down and traces its path of destruction. This list includes tornadoes with possible F5 or EF5 damage indicated by the National Weather Service as well as tornadoes with possible F5/EF5 damage by other branches of the United States government, tornado experts (i.e. After causing considerable damage there, the tornado slammed into Albion leveling the town. And Im sure the carpet cleaning crew wondered why the weather station was so busy on a Friday night in between semesters. Winds WSW at 10 to 20 mph. Compared with today, the radar data available to SELS' was rudimentary. That was the day I found my calling. I think it was around 5:00 PM when the Penn State WSR-74C radar starting showing returns (quickly strong ones) from Erie County which was at the edge of the 230-kilometer scan. A few, such as the Tri-State Tornado of 1925, are widely accepted as F5/EF5/T10+ tornadoes, despite not being rated as such in official records. They were being spotted everywhere and even in Greenville. Of these twenty-one, one was rated an F5, and six were rated F4s. Please note that Figure 11 and the following figures do not depict actual radar observations, but rather hand-drawn depictions of the supercells by NWS meteorologists. [2][3] In order to assess the intensity of these events, meteorologist Ted Fujita devised a method to estimate maximum wind speeds within tornadic storms based on the damage caused; this became known as the Fujita scale. Convective available potential energy (CAPE) at 1257 J/kg, helicity at 355 m2/s2 (which is favorable for the development of mid-level rotation) and energy helicity index (EHI) at 3.1. We heard on the radio and television that there were tornado warnings for all of northwestern Pennsylvania as tornadoes were spotted in several areas moving from the west toward the east. It's quite a privilege and honor to be entrusted by the public in this way (my research is primarily sponsored by the National Science Foundation and NOAA, i.e., taxpayer dollars). Totals vary wildly from year to year. I don't know if this fascination was because of this event happening right after we had just learned about tornadoes in school. The main severe weather feature that was unusual is seen in Figure 5 on the 700 mb chart. Farms were swept away, with debris carried for miles. Over the past 21-22 years, I have also worked in Birmingham, AL, Blacksburg, VA, and now as a Lead Forecaster in Columbia, SC. Most of these tornadoes are low-impact EF-1 tornados, causing minimal damage. Heavy wet snow on the backside of this storm could accumulate up to two feet through Monday across northern Wisconsin and the Upper Peninsula of Michigan. I lived in Camp Hill, just west of Harrisburg, so I was too far southeast to experience the storms firsthand. An ATM surveillance camera at the First State Bank in Parkersburg, Iowa, shows a house across the street being hit by an EF5 tornado with estimated winds of .
