Severe Weather 3/15 - 3/16

[Clancy]

Ok but isn’t that supercell done.

Far from it, it's reintensified over the last few scans actually.

 

[UncleJuJu98]

Well usually when they issue a mesoscale discussion for a individual supercell it never ends well. Seen this a few times and tornado usually follows or a significant one at that.

This

Looks to have sort of folded in on itself, so hopefully that will at least lessen the sigtor risk on it for the moment.

Looks like it could be close to the squall line too possibly

The cell actually looks to have intensified again and looks a bit more organized.

Watching our erstwhile poster @Fred Gossage on TN Valley Weather. They called the Columbia storm a few minutes before the NWS warning went out.

Powerflashes in Columbia, Tennessee. On Max's stream.

HUN doesn't like to issue TORs that they think aren't going to produce. They don't like a higher false alarm rate.

 

[Clancy]

Definitely looks like it could be producing. Robust and persistent couplet.

 

[Equus]

The gust front is starting to outrun the line a little south of about Aberdeen; that'd be a good trend if it continued, hampering the tornado threat along that part of the line at least. Velocities have come down a little on the last few scans along that part of the line BUT it's getting closer to the radar, so I'd expect winds to drop a little on velocity anyway as we scan lower in the storm instead of the higher winds aloft

Was wondering if it was producing. The couplet is tight
