• 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.

A grid to help you find the "7 pm CDT" maps on the GFS forecast model

I thought I'd post this to assist other noob forecasters with reading the medium/long range forecast models of the GFS. Apologies up front if this has been covered elsewhere, please add links to the other threads if it has, thanks!

So I guess I'm showing my old-school tech savvy here...I'm sure someone's got an app or something more trippy that will calculate this quicker and easier...I'm just old fashioned (relatively speaking) LOL...

I don't know about anyone else, but for me one of the challenges of learning forecasting is to read the GFS medium/long range computer models and which ones are of the 7 pm CDT time slot (few things worse than looking at a map and suddenly figuring out your looking at a 7AM or a 1PM map forecast).

So after going over the numbers in my head multiple times over the last 2 years and getting tired of it, I finally sat down and put together this simple grid to show which hours to look at, depending on the run (00, 06, 12, 18). I checked my math and believe it's correct. If not, please let me (us) know so it can be corrected. You are welcome to copy/paste it for personal use if you like. (sorry for any formatting alignment problems...seems copy/paste of text or .odt documents alters the column alignment).
