Major tornado outbreak Sunday...the aftermath..

[jkt21787]

Looks like we definately have at least two F-4 tornadoes (Dyer County, Tennessee, and Marmaduke, Arkansas).

Dyer County is an F3, not an F4 as the recent storm survey indicates. It could change as its preliminary but as of right now it would be just one F4.

I know; however, the Dyer County damage in spots looks very much like an F-4.

The problem with the Dyer county storm is it hit mainly wood frame buildings, which can be flattened just as easily in strong F3's as in f5's. However, I could have sworn the tree damage in places was of F4 intensity. There were clusters of trees on the video cut off at the stumps with foliage displaced some distance. These weren't small trees either. We'll see what else they find tomorrow. They must have a huge area to survey.

NWS Memphis is absolutely swamped. Last I heard they had 18 potential areas to survey (some from the same cells/tornadoes mind you though)

I can't find anything on the NWS local office sites...

Looking at pictures, Dyer County is definitely not an F5...agreed that it was at the most a mid-range F4 (230 mph). Marmaduke looks like it very well could have been F5...at least at the very high end of F4. Fortunate that there was still light out there or we could have seen double-digit death tolls there too.

Update on Marmaduke situation, this is from a KAIT TV met on the broadcast met board who confirmed the report that they said Memphis was going F-4 possibly F5, now he is reporting this...

"update... Despite what they said on TV, I just talked with Memphis NWS and they are preliminarily going with strong F3.

They "may" go with F4 after further evaluation."

If the Daylight Savings changes had occurred one day later, that death toll could've easily been increased.

Very true!

[Matt-hurricanewatcher]

Whats the latest confirmed count?

[CrazyC83]

Whats the latest confirmed count?

Death toll? 27

[Matt-hurricanewatcher]

Tornadoes I know there was 12 confirmed in one of the reports...But that was only for one area.

[CrazyC83]

It's hard to say as the reports keep flying around.

I have managed to get definite Fujita scale ratings for 14 tornadoes so far. I'd say the final tornado count will be in the 30-40 range.

[CrazyC83]

I think, ultimately, they will upgrade the Dyer-Gibson tornado to an F4. I'm not sure about the Marmaduke tornado; it's quite tough to upgrade to F5. They should go back and look at the structures involved.

Uh, not really. The tornado would still have occured at the same actual point in time, it just would have been, for example, 6PM instead of 7 on the clock. changing the hour on a clock does not change the point in time at which a tornado strikes, only the timestamp on the warning.

Good point in that, I got confused on that. But had it occurred an hour later, there would've many more deaths, that was the point I tried to get across.

[Beam]

Yeah, that's undeniable.

[wxmann_91]

Can anybody host a couple of 2 mb radar loops? They are going to be posted on many forums... but if somebody is able to please PM me.

[CrazyC83]

Looking at the photos from the big cell, there is NO WAY that Marmaduke was hit with only an F3 tornado. Those photos from the NWS had F5 written all over them...at least a strong F4 if the buildings were weaker. My guess is that was an initial rating and it will be increased to F4 or F5.

[thunderchief]

an f3 may level a wooden frame house but it takes an f4 to wipe the foundation clean like some of those shots show...

throw in the thrown cars and I doubt its less than an F4
