Radtechwxman Posted April 16, 2020 Share Posted April 16, 2020 Wonder what's taking so long to get final survey on Bassfield EF4. Curious if final width will be greater than 2mi and if they bumped wind speeds up Link to comment Share on other sites More sharing options...

Radtechwxman Posted April 16, 2020 Share Posted April 16, 2020 I know I'm no survey expert but I really was thinking at least 180-190mph range for this tornado based on radar data and damage Link to comment Share on other sites More sharing options...

Not guaranteed by any stretch of the imagination, but it is being considered. I mean seeing stuff like the pic below, I can certainly see why...

JasonOH Posted April 16, 2020 Share Posted April 16, 2020 Up to 190mph and 3960 yards based on the viewer. Link to comment Share on other sites More sharing options...

This is getting interesting. Edit: Nevermind, I think they are finalizing as high-end EF4. Still extremely impressive though. Link to comment Share on other sites More sharing options...

I think at this point a high risk would have more than verified. Massive outbreak with numerous violent tornadoes. Glad they kept it at moderate and issued numerous PDS/TorE's for the day. 4 Link to comment Share on other sites More sharing options...

DanLarsen34 Posted April 16, 2020 Share Posted April 16, 2020 Between the total number of tornadoes, and the total number of strong tornadoes, this was one of the most impressive outbreaks we’ve had in the past 20-30 years. Link to comment Share on other sites More sharing options...

WhirlingWx Posted April 17, 2020 Share Posted April 17, 2020 So based off of what we know so far: this event has had the most tornadoes in one continuous tornado outbreak since the 2011 Super Outbreak (>115), has had the most violent tornadoes since Pilger, NE in 2014 (2 EF4's), the most EF3+ tornadoes since the 2011 Super Outbreak as stated above (12), and the most tornadic fatalities since April 27-30, 2014 or March 2-3, 2012 (with between 30 and 37, I'm struggling to get a handle on the exact number). Then again, I used Wikipedia to get exact numbers on tornadoes in outbreaks since 2011. Someone may correct me if I'm mistaken in this. Link to comment Share on other sites More sharing options...

WhirlingWx Posted April 17, 2020 Share Posted April 17, 2020 Were the two supercells that produced the southern Mississippi tornadoes the only sustained semi-discrete supercells of the entire outbreak? From radar I can't remember seeing any others that produced (maybe I'm missing some), as many of the tornadoes came from the QLCS (and embedded supercells within it). Edit: Actually looking again I guess overnight Saturday into Sunday there were some in Texas, but other than that I can't see any other noticeable ones apart from over southern MS Link to comment Share on other sites More sharing options...
