• 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.

The winter storm discussion over the Northeast now has a new variable to it. Apparently, Rutland, Vermont experienced a major wind damage event as a result of a gravity wave or entrance into the warm sector where 50kt + winds mixed down. The entire city is without power and numerous trees and power lines are down as well as some roofs and siding of some houses. See Discussion on this thread below.

Good day,

I have seen this happen.

This is where the strong winds aloft, at the top of the boundary layer are mixed and momentum reaches the surface (example: low level jet).

This is called a NON-CONVECTIVE DAMAGING WIND event.

It occurs either from sinking air and / or mixing in the boundary layer where there is a lot of friction before the mixing occurs. This is why during a nor ' easter, there are 40-50 MPH winds at the coast, and almost no wind inland (the wind is higher up, a couple of hunderd feet or so).

Mix these winds down to the surface, especially in an elevated terrain, and you have winds at the speeds (or near) the low-level jet at the surface = wind damage!
 
Good morning,

A gravity wave is not related to the low-level jet...

That is correct, a gravity wave is more or less like an ocean wave, forming on pressure / temperature (aka density) "surfaces" which are different in the atmosphere.

These waves can, however ... Especially if the gravity wave is within the boundary layer ... Allow a strong wind aloft to become closer to, or even reach, the ground.

I was under the impression that this was a downslope windstorm and the mountains were a major contributing factor.

The wind damage was isolated in a corridor along US-7 between Rutland and Brandon, an area that runs close to the western slopes of the Green Mountains.
