• 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.

Heavy Snow Warnings with a Severe Thunder Storm Warning in the middle of it all. How often does this happen?

Lots of time when I see this , it turns out the snow warnings are for higher elevations.. I saw it a few times already this year, with these strong lows, where the rain snow cutoff is sharp.
 
We did have the severe thunderstorm warnings issued on the convective snow cells, or whatever you want to call them in Illinois a few years back (2003 or 2002).

Warnings were issued for high winds with small little snowbursts.

This brought those "snow rollers" across the area which occur rarely when winds of 60 mph or so accompany the heavy wet snow. Actually looks like people rolled them in the fashion you would when making a snow man.

From ILX:
Once the initial "seed" of the roller is started, it begins to roll. It collects additional snow from the ground as it rolls along, leaving trails behind it. The appearance is similar to building snowmen, except the snowball is more log-shaped rather than spherical, and many times they are hollow. They can be as small as a golf ball, or as large as a 30 gallon drum, but typically they are about 10 to 12 inches in diameter.

When I lived in Boulder, Colorado back in 1992 there was a spring severe thunderstorm that actually was associated with snow downbursts, hail, and lightning. It was one of the weirdest things I've lived through. But it does happen.

Thunder snow can occur during strong convective events (you can see these during particularly systems that evolve in fall and spring) and rarely can produce "snownadoes" (though these are typically waterspouts over relatively warm bodies of water). The other stuff above, however, is pretty cool :)
 
A friend sent this to me and thought I would share the NWS link of recent shots of snowrollers, which I had not heard of before. I did a search and found you had discussed them before but thought you'd still like to see these since they are rare.

At least this thread answered some of my questions such as how high the wind would have to be to start one of these.

Glad spring is here though and the weather that accompanies the increasing temps.
