That is powerful. Link to comment Share on other sites More sharing options...

blackjack123 Posted November 12, 2011 Share Posted November 12, 2011 I just couldnt help but wonder if the Tipton tornado may have been nearly as violent as the Piedmont(EF5), Chickasha(EF4), and the Goldsby(EF4) on May 24th. I know that their may certain variables on how violent a tornado is and feel someone else who understands radar better than me could answer this question. Some stormchasers were stating the Tipton tornado had some extremely intense circulation. TWC was comparing it to the Philadelphia, MS(EF5) on April 27, 2011, but I dont the Tipton tornado dug a two feet deep trench. It just seems like a violent tornado for Oklahoma in November seems very impressive. Link to comment Share on other sites More sharing options...

andyhb Posted November 13, 2011 Share Posted November 13, 2011 It was comparable to Chickasha, or at least looked very similar to it. I also strongly believe that the Canton tornado was more intense than an EF3 at it's peak intensity, the motion in that thing was ridiculous.

blackjack123 Posted November 13, 2011 Share Posted November 13, 2011 It certainly could have been, the error bars on a damage survey are probably on the order of 1 EF-scale. Its just when you see a slab swept clean it almost makes you want to think EF5, but then you must take the structural integrity of the building into account. I was just really impressed that a tornado that powerful could hit in Oklahoma in November. Link to comment Share on other sites More sharing options...
blackjack123 Posted November 13, 2011 Share Posted November 13, 2011 It also makes me wonder if EF5 tornadoes are possible during the month of November. I dont know if there ever has been any but maybe there was years ago. Link to comment Share on other sites More sharing options...
andyhb Posted November 13, 2011 Share Posted November 13, 2011 Any intensity of tornado is possible at anytime of the year... F5's hit Vicksburg, MS on Dec. 5th, 1953 and Murphysboro, IL on Dec. 18, 1957. Link to comment Share on other sites More sharing options...
brettjrob Posted November 13, 2011 Share Posted November 13, 2011 It's certainly possible. However, while I'm aware that appearance and visible motion cannot accurately a tornado's intensity, I personally feel that video of the Tipton tornado does not look as impressive in terms of either vertical or tangential motion as any of the four significant tornadoes from May 24. (That's just an observation regarding its appearance; I'm not implying anything about its real strength). Here's some very good footage from veteran chaser Martin Lisius, for anyone who's not yet seen it: Link to comment Share on other sites More sharing options...

OceanStWx Posted November 13, 2011 Share Posted November 13, 2011 It certainly could have been, the error bars on a damage survey are probably on the order of 1 EF-scale. And this is key. The more data (i.e. damage indicators) you have, the better the resulting survey will be. In this case, fortunately for this area of Oklahoma, there was only one significant structure in its path. Without knowing what the original structure looked like, I can't form any sort of opinion on that picture of the damage. I know it would be difficult to rate it an EF5 based off just one location and nothing to compare it against. Link to comment Share on other sites More sharing options...
