Seeing effective deep layer shear up to 45 to 50kts over the E central OK area now. Because of light anvil level winds, cells will probably go HP pretty quickly, but perhaps we can get a spin up or two over the next couple of hours.

Yeah, it is just along that boundary (per Mesonet and radar)...if it can converge the sfc vorticity, we might be SOL on the nowcast for this thing, Jeff. :lol:

Looks like the west-of-Kearney cell is fizzling. Another cell is firing to the north of it. The 700mb temps down here are a bit higher than they are up north -- ~9C.mikegeukes

5 reports of tornadoes in Colorado so far, nothing has been reported the last time I looked at the LSR out of Tulsa, a storm chaser reported tennis-ball size hail (2.50 inch).
Reading a Severe Weathe Statement it mentioned:
Time is MDT, not CDT

Just my luck..5 tornado reports ~100 miles away and I have to work. I will be interested to see if the faster storm motion and HP nature of the northeastern CO storms made the tornadoes "chaser-friendly". Let the monster hail, wind and downpours of the MCS begin across eastern CO and eastern OK. I wouldn't be surprised to hear of some significant flooding in northeastern NE as those cells have been training over the same area along that meso-low boundary all afternoon. The latest radar loop shows them now backbuilding. Upper-level flow was just too marginal to get any classic discrete supercells this afternoon, instead congealing the convection together into large MCSs. The only supercell that looked like it could be decent to chase via radar was that northwest of Akron, CO...and even it dove SSE and merged into the MCS, likely making for short-lived tornadoes.

Tornado Warning Leflore county in OK....egh!!! That wouldn't be fun chasing that one!

There's a good example of anvil-level / tropopause gravity waves being generated by the storms in eastern OK right now. You can see them nicely emanating from the occassional overshooting tops atop the intense updrafts.Mike Johnston

Interesting on the gravity waves, Jeff. Would they be propogating upstream or downstream of the existing convection - and do you think they might be strong enough to trigger new convection elsewhere in the vicinity later on, given the heights and boundaries around?Shane Adams
Can anyone confirm the "very dangerous" tornado in Sequayah, CO OK? I can't find the severe weather statement on CoD's log that was pasted in tis thread, and SPC's tornado reports show zilch for OK. Any chasers get this tornado?Mike Johnston

No, Shane, I wasn't on it, but you can find the severe weather statement quoted above here:

Just saw 2 different views of a funnel on a local station here in Tulsa, Not sure which county it was in. Damage videos didn't show enough to tell if tornado or straight line winds
I ended up chasing the storm from Okmulgee to Henryetta. Got 1.5" hail, and well-defined wall cloud but the circulation did not tighten enough to produce a tornado.David Schuttler

These two photos near Okmulgee and Henryetta, OK aren't even worth posting, but here they are anyway:
