• 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've read that the La Nina this year is going to stay through the spring. Does anyone know what effects the La Nina will have in the plains this spring? Does it make for a more active storm season, or does it do the opposite and make for a quiet, storm free spring?

Thanks in advance guys/gals...

My thoughts on a typical La Nina spring include some research and my personal experience. For me La Nina is the least productive for tornadoes, although I've had some very spectacular chase days in La Nina years.

- More drylines - hot and dry SW US - stronger cap firing late or east
- Less chase days and opportunities on the classic plains and high plains
- Tornadoes more common near and east of the Mississippi and eastern US
- More night tornadoes over plains (some research to support this but not conclusive) result of stronger cap
- Cold season tornado events and outbreaks (already seen this recently)
- Big Outbreak - some of the biggest outbreaks have occurred during La Nina springs. If this big day occurs and you miss it you may miss much of the season. Examples: 1974 April 3/4 Midwest US - 1974 June 8th Oklahoma. 1999 May 3rd.

Generally my La Nina years are the leanest for tornadoes unless I nail the outbreak. Outside of those years my worst chase years have been La Nina springs such as 1988, 2000.
