Substantial tornado event, Tuesday 2/28 into Wednesday 2/29

[andyhb]

The two cells in E OK and SW MO are going to become the main show in the next bit it appears

[tornadotony]

A couple of intense circulations in Barry County...

[Hoosier]

We'll have to see...but I think Lebanon may have escaped with only a weak tornado at worst and may have spared center of the city. TDS disappeared as it moved through...and that would have drastically changed if something really serious happened...

Does TDS stand for tornado debris signature? Still learning about dual-pol and trying to follow along.

The line moved over the radar site right as the tornado was approaching Lebanon so I think it's hard to make any conclusions from the returns we were getting.

A couple of intense circulations in Barry County...

Northern circulation has TDS now...very confident...but circulation weakened so possibly another brief one...

CC *shouldn't* have been affected by attenuation...but we'll await the reports...

This cell is looking ugly after a quick recycle. Good possiblity of a TOR on the ground.

Does she have a cell phone or is this a land line? Does she have a portable landline phone that requires external power?

If it's a cell phone, use SMS.

I have been keeping an eye on this activity. I'm in SE Missouri. Do you all think this will hold together through the next few hours? Haven't seen any meso disc covering our area yet. Pro met / forecaster opinions appreciated.

Yes. per SPC meso discussion 176 a tor watch is coming soon for your area.

[andyhb]

Trailer park hit in Dallas County, MO, people injured...

Shear continues to be incredible across the area and further east in the MD area.

[Macintosh]

Yes. per SPC meso discussion 176 a tor watch is coming soon for your area.

Just saw that. Looks like 3 to 4am for us.

[Wx 24/7]

Bennett Springs has been hit by high winds. 15 trailers were impacted... some of them have been damaged/rolled.

[Thrasher Fan]

not sure why the southern most storm isn't TOR warned. Looks to have good signature on SRV.

[tornadotony]

One of the keys to what is going on right now is that surface winds have stayed more backed across the warm sector than the models had indicated.
