Indystorm Posted March 25, 2021 Share Posted March 25, 2021 I must admit I am a bit baffled. We have had many tornadoes, some long tracked. The current surface low is 1002 mb in southern IL, currently deepening but not as fast as expected. I always thought a number of svr parameters were tied to the strength of the surface low, yet we have had extreme values with a low pressure not 990 or lower and many svr reports.

The environment that's been in place across Alabama has been high-end for much of the day despite models completely missing with their handling of surface evolution further west. Certainly worth discussing why it seems like models continue to miss on key details after this is over. 1 Link to comment Share on other sites More sharing options...

The tornado, at some point in its life cycle, was capable of producing EF5 damage. I have absolutely no doubt about that. However, did the tornado hit anything capable of being rated EF-5 while the tornado was at its most violent? Who knows. 5 Link to comment Share on other sites More sharing options...

Moderately Unstable Posted March 25, 2021 Share Posted March 25, 2021 There's no specific requirement not to discuss ratings--I think it's reasonable to expect somewhere along path you'll see EF4+ reports...but remember that radars, unless they're DOWs are not measuring the wind AT THE GROUND. That's super critical and why you can't take "wow look at this gate to gate shear" stuff verbatim--that's what's happening a few k feet up. Friction is real, yo. El Reno was an EF5 according to DOW...it's rated EF3. Why? No structures were hit that verified EF5. Same for the Bassfield tornado. Had an EF5 signature at times and would be super easy to believe a monster that big, on the ground that long, produced EF5 winds in a sub vortex somewhere...but clearly didn't do so over a place for which EF5 criteria could be applied. This long track, fatality producing tornado...seems rather clearly destined for EF4+ status with a special wikipedia subsection dedicated to it within the discussion about the overall event. EF5 could have verified if the tornado had gone straight through Brent...looked particularly nasty around then. It may still verify...that's what damage surveys are for. In general though..remember that velocities do not tell you what's happening at the ground unless you're right next to the radar site like now, or using a DOW. It's useful to know what the G2G is, but really the better measure is how high up debris gets lofted. There's a somewhat direct correlation btwn debris height and strength of the tornado. 5 Link to comment Share on other sites More sharing options...
