• 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.

Applying the Eta-based MOS equations to output from the WRF model has produced less accurate guidance. There will be no WRF-based MOS guidance. Verification results comparing the operational GFS and Eta MOS guidance to Eta-based MOS equations applied to WRF model output are
available at http://www.weather.gov/mdl/synop/wrfmoseval.htm .

To allow users to transition to the GFS-based MOS guidance, the NWS will temporarily run a 32km Eta model at 0000 and 1200 UTC which will serve as input to the Eta MOS. No direct model output from this interim version of the Eta model will be transmitted or made available on NWS servers. More details on this situation are available in NWS TIN 06-40 http://www.nws.noaa.gov/om/notification/ti...s_nmm_final.txt

As always, please contact us with any questions or comments you may have.

Question Rob, since you seem to know a bit more about the WRF here than I do...

To which forecast hour are they running it? I thought it was going to be to 90 or 108 hrs but I see that grid format will only be available to 84 hrs I think so I am unsure. I could've sworn I heard it was running longer than the NAM.

Thanks!
 
As the short range model of interest, the NAM runs operationally out to 84 hours. This has always been the case - now that the WRF has replaced the Eta as the NCEP operational mesoscale model it will not change. I would expect MOS guidance from the new system to be available in 6-8 months after all of the bugs get worked out and new regressions can be calculated.
 
When did the change occur? I still see the NAM running 4 times a day with the WRF only out to 48 hours. Did I miss something? I thought it was the 12z runs today...hmmm. Unless of course the new WRF is still labeled NAM and they just haven't changed it yet.
 
What might be nice is a "MOS lookalike product" using data from the soundings, so no massaging with equations but simply taking the BUFKIT type data and making it look like MOS for an easier overview...
