  7. If we had satellite and radar in 1953… • Using the 21Z Mt. Clemens (60 miles SE of Flint) sounding • NWS Detroit developed idealized simulations • Satellite • http://www.crh.noaa.gov/dtx/1953beecher/flash.php?image=3D • 2 KM radar • http://www.crh.noaa.gov/dtx/1953beecher/flash.php?image=rad2km

  12. Michigan/Ohio Tornadoes • Large F5 tornado passed through Flint and Beecher (Only F5 in SE lower Michigan) • Killed 116 people…last tornado to kill over 100 people in U.S. history • 844 injured, occurred at 830 PM EST • 27 miles long, over 800 yards wide • Three F4 tornadoes in MI/OH • Temperance/Erie; Deshler/Cygnet; Kings Mill • Four F3 tornadoes in MI/OH • $19M damage (1953); $127M damage (2002 dollars)

  17. Discussions at WBO Boston • Knew history of this weather system and saw potential of damaging/tornadic development in Massachusetts • Meteorologist Al Flahive and other staff met at 10 AM to discuss mention of “Tornado” for their next forecast issuance • Decided against it so not to be “unnecessarily alarming” • Opted for first-ever severe thunderstorm forecast wording in New England issued at 1130 AM • “Windy, partly cloudy, hot and humid with thunderstorms, some locally severe, developing this afternoon” (Credit: Chittick)

  26. Warning Issued! • Phone call made after 5 PM from Blue Hill Observatory (Milton, MA) to WBO Boston • Observer John Conover reported debris falling out of the sky • “…It’s coming from great heights, shingles, small branches, paper…boards several feet long…” • “I’m afraid there’s been a bad tornado somewhere.” • Forecaster Drebert agreed, issued first ever tornado warning in New England! • “…Caution advised on severe thunderstorms with isolated tornado activity in the Boston area between 6 and 8 PM this evening.” • Sent via teletype at 545 PM!!

  35. Worcester’s Final Statistics • F4 damage • On ground 84 minutes and 46 miles, up to one mile wide • 94 people killed, 1300 injured (#4 in U.S.) • 4000 buildings damaged or destroyed • Debris found in the Boston area and on Cape Cod • Frozen mattress found in Massachusetts Bay near Weymouth • Books and clothing found at Blue Hill and on outer Cape Cod (Provincetown/Chatham/Eastham <110 miles away>) • Reports of hail from Portland-Bangor-Eastport, ME • 1/4 to 3/4 inch in squall line, no tornadoes reported • $52.1M damage (1953 dollars); $1.14B (1997 dollars <adjusted for wealth & inflation>)

  36. Aftermath • Recently formed Weather Bureau Severe Weather Unit (SWU) in mid 1952 (SPC history) • Did well in forecasting the Iowa and Flint tornadoes, but “caught by surprise” by New England tornadoes on June 9, especially the severity of the Worcester storm • Renamed Severe Local Storms Warning Center (SELS) on June 17, 1953 • Reorganized in part because of these storms as well as Waco, TX in May (114 dead) • One forecaster and SELS supervisor requested transfer out of unit by end of 1953 • Moved to Kansas City from Washington in 1954 • Worcester Rating re-assessment • Blue ribbon committee held in summer 2005 to possibly re-rate tornado to an F5 • Only storm other than Hurricane Andrew that this was done for

  37. Aftermath • Eventual deployment of weather radar nationwide • Research radar at MIT saw Worcester tornado, only the 4th tornado seen on radar at that time • Warning system • Noted that several warnings were received by various agencies in central Massachusetts, but never passed on to other communities • Eventual development of warning system for emergency management and citizens • Improvement of radio and television communications

  38. Research • Cloud electrification of severe thunderstorms • Paper in Atmospheric Research in 1999 in honor of Bernard Vonnegut (Williams, et al) • Vonnegut researched severe storms, lightning and tornadic activity after his experience with Worcester tornado • Vonnegut and Bemus noted from 600-1200 flashes per minute in the Worcester storm • Only visual observation of stroke rate in nighttime tornadic supercell • Lightning from the storm could be seen offshore until midnight June 10 • Debris fallout from tornadic thunderstorms • Former Tornado Debris Project out of Oklahoma University • Used Worcester reports in their historic research for BAMS article in 1995 (J. Snow, et al)
