That signature is almost as impressive as the two beasts last week.

OK Purvis has about 2400 people. Hattiesburg has 46000 & isn't that far from the storm's path.

I won't be surprised if a tornado emergency gets issued for this monster.

 

[KoD]

Hoping this doesn't jostle north and brush into south Hattiesburg.

It's definitely fighting a battle with storm mode and seems embedded now... violent inflow but I wonder how much longer it holds on as a major tornado producer

It's definitely taken a little jog to the left on these last two scans.

Velocity signature is weakening a bit now.

It's definitely taken a little jog to the left on these last two scans.

Usually a sign of occlusion and weakening. But we'll see.

 

[TornadoFan]

Curious, what is velocity folding?

 

[vanni9283]

This is what it looked like a few mins ago. This looks even more intense than last Sunday!!!

 

[Richardjacks]

Curious, what is velocity folding?

Basically where the velocity scale starts over as it has been maximized...only seen on strong tornadoes

I'm surprised they haven't already done so.

Was hoping we wouldn't see another of these MDs for a while.

Areas affected...Portions of Southern Mississippi

Concerning...Tornado Watch 123...

Valid 200042Z - 200115Z

The severe weather threat for Tornado Watch 123 continues.

SUMMARY...Based on recent radar and environmental data, a strong to
potentially violent tornado with potential peak winds of 120 to 170
mph EF3+ is likely ongoing.

DISCUSSION...Recent radar signatures from KLIX as of 838 PM EDT
reveal an intense supercell characterized by a 0.5 degree rotational
velocity between 60 and 69 kt. A tornadic debris signature has also
been noted on recent radar scans. These signatures are occurring in
an environment characterized by STP between 3 and 4. Previous
signatures within similar environments produced
tornado-damage-estimated wind speeds from 120 to 170 mph and
confidence is high for a strong to potentially violent tornado. A
potential long-track tornado is ongoing and may continue based on
the rotational velocity duration and the storm moving within a
favorable downstream environment.

I wish that we had this tech & data 9 yrs back.

 

[BayouWeatherGeek]

Might pass to the north side of Purvis but it's gonna be really close.

 

[buckeye05]

Couplet looks pretty broad now. TDS is gone too. Doubt it's still on the ground.

 

[J-Rab]

Went just south of me. I have a friend near Purvis who I’m currently worried about. So much precipitation falling.
