• 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.

Tornadoes Hit Philadelphia & New Jersey 7/29/21

That video was taken from a Buffalo Wild Wings in Quakertown looking south (maybe) ... probably not the one that hit Philadelphia. The last PNS I saw said they have confirmed 9 tornadoes (with possibly another one in the Pine Barrens in an inaccessible area, so, if they confirm it, it would be an EF-U ). There are some videos of some of the other ones, but, I have not seen really good structure video of the EF-3, which, may be what you are looking for
 
@Lou Ruh Thanks for those clarifications. I put some questions about the damage at Washington Crossing Park under the other thread, can you take a look? I know you participated in the damage surveys for the event, and even if you didn’t do that specific one you certainly have damage survey experience.
 
I went back to the Washington Crossing site again and found an additional area of uprooted trees. I am still confused because just about all the damage was north of the path as drawn, and the trees were lying in a SE direction, indicating a NW wind. This seems to imply either an anti-cyclonic tornado, OR the path was drawn incorrectly. I saw maybe one tree lying SW and only one lying in a northerly direction.

Appreciate any insight on what many have happened, or how my thinking might be incorrect….
 
On occasion, especially during significant outbreaks, damage surveys often get assistance from non-NWS personnel who do not have write access to the DAT tool (I used to before a security update removed my access). Detected DIs often don't make it into DAT (for many reasons) and a rough line is drawn in DAT (assuming it even makes it into DAT ... I am not sure if DAT usage is mandatory ... it at least used to be optional).

Another piece of the puzzle could be inferred from this excerpt of the PNS ...

THE
TORNADO PATH THEN CROSSED WASHINGTON CROSSING STATE PARK. FURTHER
DAMAGE WAS OBSERVED JUST SOUTHEAST ALONG BEAR TAVERN RD. IN FACT,
SOME OF THE LARGEST DOWNED TREES WERE OBSERVED IN THIS AREA.
HOWEVER, BY THIS POINT DAMAGE BECAME INCREASINGLY UNIDIRECTIONAL
AS THE STORM'S REAR FLANK DOWNDRAFT LIKELY WRAPPED AROUND THE
TORNADIC CIRCULATION. SUFFICIENT EVIDENCE OF TORNADIC WINDS STILL
EXISTED IN THE BEAR TAVERN RD AREA

I'm not sure what your confusion is. The surface flow near a tornado is never purely tangential (i.e., circular). There is always a component of radial inflow (outflow in some dying tornadoes). If you're north of a cyclonic tornado, you're going to experience winds backing from some degree of NEly through N through NWly and probably to the W and eventually SW as the tornado passes you, if it is going SW-NE. If it is moving NW-SE, then you'll get NW winds persisting behind the tornado.
