Jeff Duda has agreed to assume ownership and lead management responsibilities during what is anticipated to be a 3-12-month interim period while we perform some updates to the site, including changing the hosting. The staff will do their best to provide timely and transparent updates throughout this transition period.

  • A website update occured last week that rendered some of the page display styles obsolete. If you have logged onto the site and are experiencing a strange or messy appearance, it is likely due to this factor. An inadvertent mistake in the meantime likely made this issue worse. It has hopefully now been fixed. See this thread for details on the fix. --Jeff

Website With Synoptic Data for Major Historical Tornadoes

When I was reaching my book Warnings from 2005-2010 there was a website that had synoptic data and patterns for various historic tornadoes (e.g., Udall, Woodward, Ruskin Heights, etc.). I cannot seem to find it today. Does anyone know if it still exists and, if so, the URL?

Thanks, everyone!!
Tornado Archive – The Ultimate Tornado Data Viewer

This is the only one that exists at the moment that I'm aware of (the tornadohistoryproject went under a couple years ago). Click on "data explorer" and there is a ton of stuff going way back. Also take a look at SPC's tornado environment browser as well, it is pretty good along with their "violent tornado webpage" which highlights events that produced F/EF4+ tornadoes.

Here are the links for those:
