A few notes:
Severe thunderstorm watch #28 was issued by SPC for northeast OK and northwest AR at 5:10pm effective til 11:00pm.
Saying a storm is "high-based" does not imply that the storm is not "surface-based". High-based, to me, means surface-based but with a very high LCL/LFC (whereas "elevated" to me, means the parcels lifted into the storm's updraft are not surface based). So the storms in eastern Oklahoma are high-based but surface-based storms.
The dewpoint depressions are still quite high (20+F) at 7:15pm, and so far the hook echoes and low level shear signatures have been transient and/or weak, so I'm not too pumped about the tornado threat.
Back to watching radar.
Perhaps tornadoes will not occur from these storms, but at least there's some good structure out there according to the spotters. Too bad it's getting dark now.
The storm just sout of Tulsa just got a storm warning for it. Okmulgee County
There are now 5 confirmed mesos. My Swift WX is showing a nice j hook from cell ID A1. Good luck for those chasing and get a twister for me. :lol:
Don't fall into the trap of relying solely on what a computer software package is constantly feeding you.
I would be very surprised if there were ANY tornadoes from today's events.
Karen, you are right in saying they mean very little. Mesocylclone and tornado detection algorithms are far from accurate...in fact, they tend to be more off the mark than they are on.

I spoke too soon. I would think from what i learned i would not jump to conclusions like that. There are mesos though but i have been informed it is mid-level rotation and i will now be surprised if we get one. I think i jumped to conclusions because i am now suffering from SDS (Supercell Deprivation Syndrome) But 2 inch hail is possible in this storm.
what is a V notch?
A radar reflectivity signature seen as a V-shaped notch in the downwind part of a thunderstorm echo. The V-notch often is seen on supercells, and is thought to be a sign of diverging flow around the main storm updraft (and hence a very strong updraft)
