Of these twenty-one, one was rated an F5, and six were rated F4's. This is the story behind the F5 tornado. W. VA The tornado finally lifted near Tionesta (Forest County) after destroying 371 homes. Like about everything else these days, tornadoes are behaving somewhat peculiarly, said Brooks, and that might be related to climate change, but they are directing some of that toward guarding their secrets. The tornado destroyed nearly the entire town of Wheatland, and seven more people were killed. Twenty-one tornadoes tracked across Northeast Ohio and Northwest Pennsylvania during the evening of May 31st. One book led to another and another and another, and the rest is history. Acres of ground were "swept bare" in some parts of town. This tornado produced possible F5 damage to a "large new home," killing the couple inside. Then it started to rain very hard and the Sheffield volunteer fire departments siren began to blow. The larger the number, the more instability is present, with CAPE of 2800 J/Kg , measured Friday evening being a moderate to high value. Marine He landed in a PSP helicopter and we talked about the relief efforts underway. Phone calls and people saying that tornados were hitting all around us. 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). It was a blur of activity for about three hours and then just as suddenly as it began, it wasover. Farms "entirely vanished," with debris carried for miles. It appeared that one of the tornadoes had touched down north of Tionesta, crossed the Allegheny River, hit the German Hill area, then north of Marienville near the Abraxas Center, and travelled on toward Kane. A tornado rated an F5 had winds great than 261 MPH. Thomas P. Grazulis Ted Fujita), or meteorological research institutions (i.e. The F5 rating is widely accepted. One station I was updating was WKZA in Kane, a daytime only AM station (it no longer exists). 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. My father always listened to the scanner at night and his room was across from mine. An extremely powerful tornado, rated T10. I worked at Weather Services Corporation from 1980 until 1988 before starting my own business. The strength of the front and the degree of instability lead to the erosion or breaking of the cap and thunderstorms exploded with violent results. With vast landmasses beneath subtropical, moisture-laden air surging from the Gulf of Mexico and its polar opposite sagging from Canada, the United States is a world capital of tornadoes. I graduated in 1993 from the University with my BS in Meteorology, and in August of 1993 I began my National Weather Service career in a small Weather Forecast Office in Wichita Falls, TX. I was a grad student at Penn State during the Moshannon tornado outbreak on 31 May 1985. An entire section of the town was swept away. NWS Pittsburgh. 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). Unfortunately, the tornadoes that hit Warren, Forest and Venango Counties on that fateful night thirty years ago were very destructive in terms of property and life. These storms were heading toward Kane and had produced tornadoes that created considerable damage and injuries in western Pennsylvania. They had their hunting camp in Clearfield County near Parker Dam State Park. I never saw such yellow, greenish tint to the sky as I did that day. They were still looking for survivors in townand also in Niles as well. Over a thousand homes and businesses were damaged or destroyed in the county. 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. Around 10pm, during one of the top-of-the-hour commercial and news breaks, the top story was that there had been deadly tornadoes earlier that evening in Ohio and Pennsylvania, though details remained sketchy at that point. The second F4 to affect Erie County touched down between Wattsburg and Corry in eastern Erie County. The winds estimated by the Fujita Scale are estimated values and have not been verified scientifically. The three ingredients needed for thunderstorms are lift, moisture and instability. As mentioned earlier, wind shear, or more importantly wind shear of the right magnitude and direction, will cause thunderstorms to rotate, which is a precursor to tornado development. Jamestown, Wheatland, Niles Oh. This is a map and list of tornadoes since 1950 which the National Weather Service has rated F5 (before 2007) or EF5 (equivalent, 2007 onward, the most intense damage category on the Fujita and Enhanced Fujita damage scales. [I previously wanted to be an astronomer; I subconsciously was probably already looking for new areas though, because as I learned more about astronomy, it became clear that the days of visual astronomy (i.e., looking through eyepieces and making discoveries) were long gone.] An F3 tornado killed two people in Centerville with an F2 killing one person near Linesville. I was already deeply interested in weather and hoping to go to college to become a meteorologist. Nature can be very, very powerful. Retrieved from: https://www.weather.gov/ctp/TornadoOutbreak_May311985#MeteorologyM. The scale ranks tornadoes from F0 to F5, with F0 being the least intense and F5 being the most intense. Tragically, three or four people were killed (I think a man living in mobile home and two teenagers out in the woods), but I was amazed at how many were not hurt after viewing the destruction. The residents of Ohio and Pennsylvania will long remember May 31st, 1985. A clear echo was evident, the calling card of a powerful tornado. The following diagrams, called soundings, show the amount of instability in the atmosphere that afternoon. We lifted off and the tornados path of destruction was easy to follow from the air. At the same time, conditions in the upper atmosphere continued to become more favorable for an outbreak of severe weather. Beginning in 1971, tornadoes were rated by the NWS using on-site damage surveys. Because the distinctions between F4/EF4/T9 and F5/EF5/T10 tornadoes are often ambiguous, the official ratings of numerous other tornadoes formally rated below F5/EF5/T10 or equivalent have been disputed, with certain government sources or independent studies contradicting the official record. People were hurt from flying debris. Homes were swept away, with only a bathtub remaining on one of the foundations. This tornado is considered the only F5 on record in Arkansas. 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 31st. 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. PORTIONS OF THE NORTHERN PANHANDLE. Well-built homes were swept away in four counties with F5 damage in the town of Pomeroy. Cars flipped around every which way. Winds WSW at 10 to 20 mph. We assumed that this would be a dynamics drivenevent and the greatest dynamics were located closer to the surface low moving over Sault Saint Marie. TOWARDS THE EAST AT 35 MPH. Greg Forbes, myself, Fred [Gadomski], and Paul [Knight] were mesmerized by the radarand, out of the dead silence, Greg pronounced that "People are dying right now." Around here, the ideal air masses are present in summer, said Brooks, but the ideal winds tend to occur in winter. More on that later. From that point on through the evening, weather conditions worsened. The sounding of Figure 6 shows a small capping inversion near the surface and an inversion from roughly 850 mb to 550 mb. Some tornadoes form independently from supercells. As the first reports of damage trickled in to the National Weather Service offices in the area, it quickly became clear that a tornado outbreak of an unprecedented magnitude was taking place across the region. 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 Wheatlands businesses and industries were destroyed or badly damaged including Yourga Trucking, B&D Trucking, Steel Trucking, R&J Trucking, Sharon Metal Fence, Wheatland Tube Co., two plants of Sawhill Tubular Products, N/S Corp., William Orr Co. and a Bell of Pennsylvania maintenance garage. May 31, 1985 changed my life forever. Parts of Oakville "vanished," with house debris scattered for miles. By the end of the evening, a total of forty-one tornadoes had occurred in the United States and Canada. One notable survivor: 1 year old Elvis Presley", 10.1175/1520-0493(1939)67<176:tcmt>2.0.co;2, "Top Ten Deadliest Oklahoma Tornadoes (1882-Present)", F5 Tornadoes in the U.S. since 1950 (SPC/NOAA), Climatological Risk of Strong and Violent Tornadoes in the United States (Paper 9.4, Second Conference on Environmental Applications), Severe Thunderstorm and Tornado Climatology (NSSL), List of strong tornadoes from 1879 to 2000, https://en.wikipedia.org/w/index.php?title=List_of_F5_and_EF5_tornadoes&oldid=1149715856. Low around 35F. ANOTHER TORNADO SOUTH OF SPARTANSBURG MOVING INTO WARREN COUNTY AND ONE NORTH OF OIL CITY MOVING INTO NORTHERN FOREST COUNTY. Some of them 1/2 mile wide. Back on May 31st 1985, the state of Pennsylvania was the epicenter of a severe tornado outbreak, the deadliest in our state's history. Der Omaha F5 war der strkste Tornado, der jemals durch Nebraska gerissen wurde. Many other tornadoes have never been formally rated by an official government source but have nonetheless been described as F5/EF5/T10+ or equivalent, often by independent studies. "If I'm going to die, I'm not going to die alone," I said to myself, and off I ran to my neighbor's home. These indications can come from the United States government, Doppler on Wheels, tornado experts (i.e. I can also remember all the tornado warnings that were issued for the area as the storms moved in. Radar images dont show the actual tornadoes themselves (see the videos in the next section for that), but instead show structures or signatures within the storms that produce tornadoes. The sky even seemed to have a dark green color to it. Valley Baptist Church and at least 50 homes in Wheatland were wrecked; 70 homes in Hermitage were destroyed or damaged; and at least 46 buildings were destroyed or damaged in Lackawannock Township. SOUTHERN LAKE ONTARIO I lived in Camp Hill, just west of Harrisburg, so I was too far southeast to experience the storms firsthand. Twenty-one tornadoes tracked across Northeast Ohio and Northwest Pennsylvania during the evening of May 31st. Thornburgh returned on Tuesday with Vice President George H.W. In all, 43 tornadoes touched down between about 4 and 11 p.m. that Friday in an unstable weather front stretching from Ontario, Canada, through New York, Pennsylvania and into southern Ohio. It was MemorialDay weekend and the traffic was lighter than usual for a Friday. Full, unedited video of a rare, western Pennsylvania, F5 tornado filmed by Ron Alfredo as it made it's way through his parents-in-law neighborhood on may 31, 1985. Hurricane Camille in 1969 down in Mississippi, and I saw Hurricane Agnes in Wilkes-Barre, Pennsylvania. They were. We also install outdoor concrete tornado shelters. Thirteen small businesses were destroyed including the Shenango and Ohio Street hotels, Yankevich Auto Recycling, Valley Radiator and a Peter J. Schmitt food warehouse. The company gave $100,000 for a borough disaster fund and the other $50,000 established a Valley Baptist Church Rebuilding Fund. I recall being fascinated by how the weather could be so interesting yet so deadly. I was amazed at how that night produced the only F5 tornado to strike PA. That statistic remains so even today. Please try another search. Call us today to receive your Free Estimate! Click on a tornado name in the table below to view more details about each tornado. After the F5 tornado hit on April 3, 1974, ten sirens were installed across the area. Then, sirens. Even though my immediate area wasn't impacted by a tornado, the power of those storms as they moved through really peaked my interest in weather. Over a dozen tornadoes occurred in Ontario, with at least four F3s and two F4s reported. This was my first severe weather shift as a lead forecaster. It was rated F4, traveled more than 60 miles across rough terrain, and at times had a damage path width of around 2 miles. May 31, 1985 Tornado Outbreak: 34th Anniversary. Very early the next morning (probably around 3-5 AM) , the remnants of the storms moved across southeastern PA. That was the end of the convection for the evening and just as suddenly as the event started, it was over. Among the hardest hit communities were Newton Falls and Niles, Ohio; Albion in Erie County; Atlantic in Crawford County; and Wheatland and Hermitage in Mercer County. [15][16] From 1950 to 1970, tornadoes were assessed retrospectively, primarily using information recorded in government databases, as well as newspaper photographs and eyewitness accounts. On May 31, 1985, many Pennsylvania residents faced injury, property damage, and even death due to a huge tornado outbreak, the largest and most intense tornado outbreak ever to hit this area of the country. Twenty-one tornadoes tracked across Northeast Ohio and Northwest Pennsylvania during the evening of May 31st. But the state also experiences tornadoes of EF-3 category and above. Farms were leveled and a truck was thrown 300yd (274m). What followed was atmospheric fireworks. And Im sure the carpet cleaning crew wondered why the weather station was so busy on a Friday night in between semesters. According to Sleptzoff & Dunkle (2009), on June 1st, the Governor of Pennsylvania asked for federal relief to help with the damage left by the May 31st tornado outbreak. Thomas P. Grazulis Ted Fujita), or meteorological research institutions (i.e. Eleven farms were completely leveled or swept away. That all changed during the afternoon and evening hours of May 31st. Summer president Brian Orzel updated all of the CWSs radio stations with tornado watch information hours before the storms hit. The storms seemed to just explode in the matter of minutes and the radar returns were much stronger than any I had ever seen at that distance on the Penn State radar. Dry, gusty winds will promote critical fire weather over southern Arizona Monday. Precipitation looks like a hook on the radar returns; showingrain, hail and sometimes debris caused by the tornado, spiraling inward around the tornado circulation. Getting something as big as far east as you is really hard, he said. Tragically, these tornadoes killed 66 people in Ohio and Pennsylvania. We could see supercells developing north of Lake Erie and racing northeast. Richard Thornburgh visited the Shenango Valley over the weekend and at his request, President Ronald Reagan issued a federal disaster declaration on Monday. Nine years later, I left home to pursue a degree in meteorology from the University ofOklahoma. Twenty-one tornadoes tracked across Northeast Ohio and Northwest Pennsylvania during the evening of May 31st. After causing considerable damage there, the tornado slammed into Albion leveling the town. Questions? We were unable to track a subsequent, deadly tornado that roared through the Elimsport/Watsontown areas. This was the deadliest tornado outbreak of the 1980s, killing 89 people, injuring more . Tornadoes get their spin when winds blow in different directions in a column of air. This page will focus on the tornadoes that impacted northeastern Ohio, far southwestern New York, and Pennsylvania. The following sounding is from Dayton, Ohio (DAY) the morning of the 31st. 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. Cochranton, Cherry Tree, Cooperstown and Tionesta were also hard hit. Another was carried for 200yd (600ft). I have never seen a sounding in Pittsburgh look so bad. Another measure of instability is the Lifted Index (LI). Erie County, Pennsylvania was also affected by devastating tornadoes. 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 depicts 2800 J/kg of CAPE in the vicinity, therefore indicating a moderate to high value of instability in the atmosphere for severe thunderstorms. This storm was headed directly for our office, but it collapsed and died completely before reaching the PA border with OH. Those lost never will be forgotten. What happened next is historyhistorical damage and destruction. Back in State College, interest focused on tracking a large supercell on radar that was paralleling I-80. [12][13], The tornadoes on this list have been formally rated F5 by an official government source. The outbreak produced the only F5 tornado on record in the state's history. 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. For a horrifying day, a tornado alley cut through Pennsylvania. Over a dozen tornadoes occurred in Ontario, with at least four F3s and two F4s reported. Several other tornadoes have also been documented as possibly attaining this status, though they are not officially rated as such. However, as the afternoon progressed, the thunderstorm activity developed south into northern Ohio. READ MORE: Storms disrupt SEPTA rail service; EF-2 tornado damages dozens of homes in Delco. He said researchers have seen a change in tornado variability. [9] Outside the United States and Canada, six tornadoes have been officially rated F5/EF5/T10+ or equivalent: two each in France, Germany, and one in Italy and Argentina. Tornadoes are among the most violent known meteorological phenomena. Twenty-one tornadoes tracked across Northeast Ohio and Northwest Pennsylvania during the evening of May 31st. Although we had access to single-site reflectivity data from some locations, there were no regional mosaiced products for us to "see the big picture." I have worked for the National Weather Service for 15 years now and still love thepower of the atmosphere and probably always will! National Hurricane Center It's far from clear what I'd be doing right now had it not been for the 5/31/85 tornado outbreak (and also perhaps had we not learned about tornadoes in school just before the outbreak). Tornado Warned Supercells In The Homeland Producing Hail +Beautiful structure, Tornado and huge hail Central Kansas 4/19/2023. It looked like it was bombed. This massive tornado swept away or leveled 235 out of 247 structures, more than 90% of the town, killing or injuring a third of the population. 10 violent (F4 or F5) tornadoes; 12 killer tornadoes 89 fatalities (65 in Pa.; 69 tornado deaths in Pa. in previous 50 years) Damage estimated in excess of $600 million ($1.5 billion in. But tornadoes have a long history of peculiar behavior. One entire farm was swept completely away. I worked the evening shift at "SELS" (the Severe Local Storms Unit of the National Severe Storms Forecast Center, as the Storm Prediction Center (SPC) was known in those days) on Friday, 31 May 1985. An EF-5/F-5 tornado has been documented in 19 states, ranging from as far north as Fargo, North Dakota, to as far south as Central Texas and as far east as Ohio near its border with Pennsylvania. I was especially saddened to find out that our favorite ice cream stand in Tidioute PA had beendestroyed by the tornado that passed through that lovely little town. This image, courtesy Greg Forbes via Paul Markowski, is from the radar that was atop the Walker Building, home of Penn State Meteorology Department, around 8pm EST. I was not working that day. At least 695 . REMEMBERA TORNADO WATCH MEANS CONDITIONSARE FAVORABLE FOR TORNADOES AND SEVERETHUNDERSTORMS IN AND CLOSE TO THE WATCH AREA. Only one F5 tornado has ever landed on the city. Farms were swept away, with debris carried for miles. Please select one of the following: Local KCLE Standard Radar (low bandwidth), May 31st, 1985 Tornado Outbreak The 30th Anniversary, EMA Response & Technology of the Day, The 1985 Tornado Outbreak Revisited, National Oceanic and Atmospheric Administration. The Black Friday Tornado Outbreak in Ontario [PDF file]. Following are several images of what the thunderstorms looked like to meteorologist on radar. Registering F5 on the Fujita scale, it remains the only F5 in . Storm Prediction Center, Weather Safety It's been a heck of a ride. The outlook from SELS [now the Storm Prediction Center] was a moderate risk of severe storms and tornadoes. My mother took me and my brother to the library regularly during the summer. The tornado finally lifted south of the town of Mercer after damaging or destroying more than a thousand homes. The increasing wind speed with height and change in direction, known as wind shear, is what helps thunderstorms to rotate and be capable of producing significant tornadoes. THEY ARE ALL MOVING TO THE NORTHEAST AT NEAR 35 MPH. With all that transpired, many survived. [6] The Enhanced Fujita scale is used predominantly in North America. The diverse air masses clearly have a whole lot to do with igniting the supercell thunderstorms that are the source of some of the most dangerous tornadoes, but indicting those ingredients alone would be a gross oversimplification, according to the Storm Prediction Center.
