MOST DEATHS IN A SINGLE BUILDING -- about 70 at the Copper Pants Factory in Gainesville, Ga on April 6, 1936. The building was hit by the tornado, doors were probably locked. It caught fire and burned to the ground, along with nearby buildings. The total of 70 is an estimate.

The May 2, 2021 outbreak qualified it as an "insignificant" outbreak with only one F2 tornado, putting it under the 1000th most intense outbreak since that 1950. The NBC Al Roker type of hype is really unnecessary . Zero killed, zero injured tells us the whole story.

19 years of research on Louisville tornadoes will come up with better numbers, for sure. SIGTOR 1680-1973 WILL HAVE 115 deaths at Louisville in 1890. I knew that 14 ago. Kevin was nice enough to send me a copy of his book.

66 tornado reports for November 29/30, 24 actual tornadoes. 5 EF2 2 EF3 ...that's a score of 20. Just barely made it significant. Is there a report of an EF4 in there ?? Nothing listed on wiki out of Iowa State .

AN OUTBREAK !..FINALLY.. After 111 days since 3/25/2021, Iowa, but a "SMALL" one. NOT SIG 1 EF3 and 2 EF2s (46 EF0/EF1 don't EVER count). Since 2011-present each 2-year period has fewer sig outbreaks. THIS WINTER ?/ NEXT YEAR ? WILL IT BE LIKE 1986-1987 ? OR 2011 ? MUST WAIT

THOSE F5 RATINGS WERE DONE AT A VERY DIFFERENT PERIOD IN TORNADO DOCUMENTATION, AND NOT BY ME, REALLY. THEY WERE DONE BOTH BY TED FUJITA AND THE STUDENT IN 1973, REPORTING TO NSSFC. BOTH GAVE THEM AN F5 WITH NO REAL ON-SITE STUDY, SO BE CAREFUL.

So much for May 15th, the 17th is the target date, then on to record territory. Strange weather since mid-1980's. What's not strange is the 70 EF0's and EF1's this month. As chasers and tech get better, more of those show up. Last true outbreak was March 25th.. 50 days ago.

56% of SIG outbreaks since 2012--in COLD weather. After the polar vortex of 1985, 7 of 7 SIG outbreaks--ALL in COLD weather. WE NEED A CLASSIFICATION SYSTEM TO KEEP TRACK. 2021 - March 27 + April + May to June 7 -- 72 days with no SIG outbreaks. You'll have a system in 2 weeks

post 3 of 3 Kickstarter began 2009. Indiegogo 2007. My version in 1992: SIGTOR 1680-1991 was $65 if willing to wait a year. Goal was 200 books, or forget it. My goal now is 200 books at $145, free shipping. Higher price at a future date. Goal not reached- $ returned- I quit

November 4th--the first true "outbreak" in 4 months. Climate change! The idea that what's coming up in SIGTOR is "Volume 1" is now gone. It will have a major revision of how we classify outbreaks. Still hoping that Kickstarter comes though. All time high temp in VT for all Nov.

WORST OUTBREAKS IN MAY. No major outbreaks in 14 years. COMING SOON: JUNE ... Slowly becoming a month of landspouts ... courtesy of extra CO2 , methane, water vapor, and other greenhouse gases. With nothing I would call an actual "outbreak". Once was a great month.

Yesterday--no book post. Walk in the woods on a nice early climate change day. 40 degrees, blue sky, perfect alto cumulus. Mud season starts tomorrow. What's ahead? Floods, high heat, drought, more ticks, frightning TCs. I'll try to enjoy 3 straight months with record highs.

POST #1 of 2 SIGTOR 1680-1991 was $65 in 1992. Too broke to print. Deal was somewhat like"Indiegogo". Needed 300 customers to send $65 and wait 6 months. You would get the book or get your money back. Got 300+ orders. The price went to $95 in 1993. Printer went bankrupt in 1999

Having viewed 25 rotating TX LP supercells, I think it's OK to say May 17 had no significant outbreak ... no 4 EF2 ... no 2 EF3 ... no 1EF3 and 2EF's ...nothing to make a SIGNIFICANT day. May 26 is the day for a new milestone for climate change. ..61 DAYS ... .no real outbreak

@tornado_talk @NWSJacksonMS Every F5 rating before 1980 is an "educated wild guess". From 1880-1979 I looked at the tornadoes that seemed the most extremely violent and took a guess at the ones that were really compelling, but it was still just a guess. The gut feeling on Vicksburg was poor construction
