I'm at work so will be in and out for awhile...will grab what I can.

that is fine I am not going to post any svr warnings unless they are significant because already we have a lot of them so I will post tornado warnings only

I usually post only tornado warnings unless thunderstorm winds (thunderstorm warnings) are at 80+ mph or the warning is near a members home location.

I usually post only tornado warnings unless thunderstorm winds (thunderstorm warnings) are at 80+ mph or the warning is near a members home location.

I figured that I was just posting them all because the outbreak was just getting going and I also figured I would post if it states something has been observed

what is the difference between ETVS and TVS

[brunota2003]

Watch any storms in SD/WY that travel right of due north (or NNE/NE). According to GR, all the storm tracks have the storms moving to the NNW/NW, except 3. One was the Kimball tornado warned cell, one was the one over Gering (which is now tornado warned), and one is south of Kimball (not tornado warned...yet, but I think it will be around the time it hits Kimball.)

yea the NNW indication means that those storms will not block inflow of the storms moving NE

what is the difference between ETVS and TVS

ETVS is a tornadic signature that is likely not reaching the ground (stable wind layer at the surface).

I think ETVS is Elevated (notice it says the base is around 12300 I believe)...could be wrong though.
