Several warnings issued for North Central and NE Okla. Giant MCS moving in on those areas.

After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.
I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.
For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.
From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.

That MCS may achieve derecheo-like characteristics intermittently today. The derecheo checklist is far from being met at 500 mb, mainly due to lack of a decent shortwave. However 700 and 850 mb warm air advection is in progress, which is on the checklist. Also the airmass is extremely unstable and exceptionally humid. SPC upgrade to MDT is clearly justified. Enjoy the show but be safe and respect the wind.

I agree with Jeff this storm is trucking along which is typically a characteristic of a derecho and just received a report of 85MPH winds near Tulsa and hail larger than 2" has also been reported near I35 in N Oklahoma. The SPC has issued an MD mentioning an upgrade to a moderate risk over Arkansas by the 1630z outlook and for good reason. I would also be watching those isolated cells developing along the boundary ahead of the MCS.
Edit: Supercell ahead of MCS has split and the right mover is riding the boundary.

Northern end of the MCS has just gone warned east of Adair OK. Showing 55kts of shear.
Darren Stephens
Southern end of MCS near the Northern portions of McIntosh County is bulging quite a bit more. Persons in that area should pay close attention.
Gotta love this: PDS Severe Thunderstorm Watch issued for the area downstream of the bow echo.

Wow, that bow echo is extremely impressive. Both SR and base velocity at tilt 1 showing winds between 70-100knts. That'd be awesome to intercept, that's for sure.

That is a really impressive derecho. It's been consistently showing a LEWP/ mesovortex on the southern edge, just about 30 miles west of Little Rock, could probably use a Tor warning if it wraps in any more.
Any bets on how far this thing goes? I wouldn't be surprised to see a big blue smear on the SPC reports page all the way down to Florida.

Here's a power outage map but it's not working at the moment:

Maybe too many people trying to get on
Tornado warning now on the northern edge. Looking for webcams now.

Any Chasers in AR??
Hmmmm... I don't see any active chasers in AR on TVN??
I have heard from other chasers that they don't like to chase storms into AR for the following reasons: 1. Too many hills 2. Too many streams to cross and lakes to detour around. 3. Roads that seems to be going NOWHERE! 4. Did i mention hills??
Unless they have extended the Vortex2 project by one more day, guess this will be the last chance chase for them or any other chasers to do for this week.
Sigh...

Clearly recognizable TVS signature just SW of Vilonia, AR at this time on the leading edge of the bow. Reminds me a lot of Kansas City tornado/bow echo nocturnal incident last year. Looks to pass just south of Vilonia.

I'm going to say central/eastern GA as the RUC shows decreasing shear down that way. Instability remains strong, however I do see a lot of storms developing rapidly in front of the system, which may act to slow down the cold pool.

TX should please be added for this thread. An active area of cu is starting to show up W of the DFW metroplex. Huge amounts of CAPE and good flow are present. Primary concern will probably be large hail, but spc has issued a large tor watch box for the area. I'll be camping up near Pilot Point, and will be watching things very closely this evening.

Very nice supercell in Jack County TX, just NW of DFW. A "developing tornado" already reported with this storm. So far I haven't found a live stream, but there have to be plenty of chasers on that cell.
Edit: SPC mesoanalysis is reporting CAPE over 7000 in that area now! Wow. I'm not sure I can remember ever seeing a storm actually go up in that kind of instability. The TX storms appear to backbuilding somewhat against the mean flow, they haven't budged much off the dryline since initiation. That can only help any tornado chances.
