Severe weather outbreak - May 29-31

[Category 5]

That could easily be an EF4 or EF5 tornado on the ground...

I wouldn't jump to that conclusion without daylight. We didn't know how bad Greensburg was until the sun came up. Reports are indicating a violent tornado, but I want to see it lit up first.

10:45 but the hook seems to be merging into the bow...

What happens when it does this ?

Hopefully the cell becomes absorbed and I can go to bed.

Base velocity is showing some 65-70 kt winds at 4500 ft with the bow echo in Republic County.

Omaha radar still shows a couplet, but maybe not as impressive as a few minutes ago. Headed in general direction Beatrice.

[Bunkertor]

*OT* Oh no, now 2" hail over here.

*OT* Oh no, now 2" hail over here.

Not really OT, thread title just has severe and a date period.

The 5 cm hail is falling in Hamburg?

[btangy]

Beatrice is a relatively large town (pop: 12,921). I agree that the rotational couplet is decreasing in intensity, but there still could be a significant tornado on the ground. Now it is rain wrapped and well after dark so it remains a very dangerous situation.

Not really OT, thread title just has severe and a date period.

The 5 cm hail is falling in Hamburg?

No, not in Hamburg, near Cologne / Düsseldorf. The cell was travelling from the swiss border to the north throughout the night and finally delivered...reports from skywarn and UWZ.

It carried violett warnings the whole time which is little under MDT in U.S 4 unconfirmed tornado reports, yet.

Beatrice is a relatively large town (pop: 12,921). I agree that the rotational couplet is decreasing in intensity, but there still could be a significant tornado on the ground. Now it is rain wrapped and well after dark so it remains a very dangerous situation.

Latest warning says it is West of Beatrice, and moving East, but says mainly rural areas will be effected. Not quite sure of that reasoning.

I guess, technically, the 'otherwise' means they are including Beatrice, but usually warnings are more explicit.

[Category 5]

It appears to be fully merging into the line, signs of rotation are starting to diminish.

[Ed Mahmoud]

It appears to be fully merging into the line, signs of rotation are starting to diminish.

But a small, but impressive, bow is starting to head for Beatrice. Wind damage seems probable, and a tornado may still be on the Northern tip of that bow, from viewing NWS radar without any cool software.


One of these days, maybe for the 2009 season, I might look into that...
