Severe Weather Threat April 1-4

[Kds86z]

Mesocyclone appears to be strengthening on radar. Has a TBSS from large hail but certainly has a look of something possibly tornadic...

Def has the look

 

[Tennie]

There's a supercell near Woodstock, IL, whose mesocyclone seems to be strengthening. It should be watched for severe potential.

The cell near Ottumwa, IA, has an impressive TBSS on it. It matches up well with an equally impressive hail shaft that Max Velocity showed on his stream a few minutes ago. I wouldn't be surprised to see reports of hail over three inches in diameter coming out it.

Inflow ramping up. Hook echo forming

It looks like the Iowa line is starting to make contact with the Keota cell (particularly in the upper levels). We'll just have to wait and see what effects this incoming nudge ends up having...

Oh.. hook

I'd watch cells here as well:

It's the claw!

 

[Tennie]

The cell north of Washington, IA, is starting to form a noticeable hook echo. It may be preparing to go crazy, or it may not. Let's see which it is.

The ML rotation track has very consistent rotation from Ottumwa to present; very surprised it has not dropped anything yet. Seems to be gearing up.

OTG per Copic's stream I'm watching

Dropped right on top of him. That was nuts.
