Of course on 4/27 these parameters were on a larger scale... Link to comment Share on other sites More sharing options...

1900hurricane Posted April 2, 2017 Author Share Posted April 2, 2017 I don't like the situation surrounding that cell headed for Vicksburg. That mesocyclone is embedded in very high reflectivity and KDP. If there is something there, nobody is probably seeing it. Link to comment Share on other sites More sharing options...
Indystorm Posted April 2, 2017 Share Posted April 2, 2017 Does make me wonder if gamblers on riverboats on the Mississippi receive a warning or if management provides any shelter in a situation like this. Link to comment Share on other sites More sharing options...

I have no idea if there's anything on the ground, but it looks pretty decent now as it's in some impressive parameters. It's a shame storm mode is so messy, this could've been an even more impressive event. Link to comment Share on other sites More sharing options...
Torchageddon Posted April 3, 2017 Share Posted April 3, 2017 Just got on and saw it was a High Risk...why? I read the outlook and still don't get it. SRH is extremely high and what else? There isn't even a single sig report in the prelim. list. I didn't see the radar in the middle of the afternoon but was there any discrete activity where the high risk was outlined?

I'll use the example Patrick Marsh did on twitter with 4/26/2016. There were 3 tornado reports day of, ended up with over 40 tornadoes. Also, there are areas that are sparsely populated where the strongest radar signatures were. The reports will come in and I have no doubt that the outlook verified.

The image below shows the tornado emergencies issued (3) -- white icon with the black circle around it. It shows the spotter network reports (the white triangle outlines) and the radar confirmed tornadoes (the slighly transparent red / black icons) ... black was warning indicated LARGE tornadoes. There was definitely some real activity in the high risk area. The BRIGHT red triangle is an LSR. There is a lot we know and none of it is logged as local storm reports yet.

I'd add that not every high risk area has to turn into a massive event with several dozen tornadoes, particularly in this case with the *relatively* small high risk area as was mentioned earlier.

Not so much a delay, but I can speak from experience... when you're busy throwing out tons of tornado warnings and follow up statements, writing down reports... getting an actual LSR on the computer out in the middle of the outbreak is the least of your concern. The local offices likely have a ton of LSRs they haven't submitted and will not submit until everything dies down. Its simply not as important as actually warning people about the ongoing threat.
