• 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 didnt really know where to put this topic, so I put it here, if its in the wrong board, please forgive me. Anyway, does anyone know where I can find and bookmark up to date severe weather indicies such as K Index, Lifted Index, Showalter, SWEAT, all the different CAPES, cross totals, total totals, and the bulk richardson? If you know of one website in which all of these were on them that would be great, however multiple websites would work too, as long as they get me the information I need. Thanks!
 
A quick Google search turned up numerous sites, though the following sites and publications will provide for some good reading:


NWSFO LSX (Saint Louis) Convective Indices


NWS Louisville: Convective Parameters and Indices

Ohio State Severe Weather Products

Guide to Thunderstorm Stability Indices

Explanation of SPC Severe Weather Parameters


Rasmussen, E. N., and D. O. Blanchard, 1998: A baseline climatology of sounding-derived supercell and tornado forecast parameters. Wea. Forecasting, 13, 1148-1164.

A Baseline Climatology of Sounding Derived Parameters Associated with Deep, Moist Convection (Craven, Brooks, and Hart, 2003)

Davies, J.M, 2002: On low-level thermodynamic parameters associated with tornadic and nontornadic supercells. Preprints, 21st Conf. on Severe Local Storms, San Antonio, TX , AMS , 603-606.

Estimations of CIN and LFC Associated with Tornadic and Nontornadic Supercells (Jon Davies)

There are also many other good publications that deal with indices, though you (or your institution) needs to have an AMS online publication login...
