• 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.

    Sincerely, Jeff D.

I was watching that on radar hoping it missed NY even though it was a day I planned on chasing, the reflectivity values were like a hail core even though it was a squall line, and the radial velocities showed 90mph outflow only a few kft up, with 80 mph outflow only hundreds of feet off the ground, it looked like cat 1 hurricane conditions with hail added

I'm still confused by reports of cars flipped, if they were not moving when they flipped this sounds more like tornado damage than outflow wind

I would not be surprised if there were some tornadoes embedded somewhere in the line at times. That is not unusual with derechos.

Me neither, it looked on radar like the updraft was right next to the gust front, with the extreme outflow winds producing a lot of shear where they met the inflow and even brief hook echos, But even so I am not used to QLCS tornadoes being strong enough to flip cars, around here they seem to all get rated EF1
 
Most QLCS tornadoes are on the weaker end of the scale, but occasionally they can be stronger. I know of a number of cases of EF-2 or stronger tornadoes associated with QLCS systems. Sadly, around 15 years ago, one took the life of the husband of a co-worker of mine when it hit a shopping area in Fairview Heights, Illinois. A tornado strong enough to flip a car is definitely possible in a derecho.

I'm sure it's possible, it just seems like an unusual and notable event in the absence of embedded supercells
