Just to add some interest to the GPSL launch, it looks like the GFS forecast that everyone uses for prediction software is getting a major upgrade the Wednesday before. The announcement is shown below.  I am a little confused on exactly what is happening to the existing files (0.5 and 1.0 degree) that most systems use.  Since there is a new directory structure it would be nice if both systems could be up for a while but it doesn't sound like that is in the cards.

The pessimist in me says we should all be prepared for none of the prediction software working Friday or Saturday.  The best and most likely case is everyone will get the software converted over with a little down time on Wednesday.  I plan on working on mine so it is ready but will be traveling on Wednesday so it might be interesting.

If any of you have contacts at Hahhub or any of the other prediction systems it would be great to hear their plans.

Mark Conner, if you have any insight it would be great to hear that as well.

Summary

* GFS will have a major upgrade with the 12z cycle June 12. Starting with the 12z cycle June 12, GFS data will move to the new directory structure of gfs.YYYYMMDD/CC/ from gfs.YYYYMMDDCC/. Data will not be backfilled.

* Grib filter for the parallel GFSv15 0.25 deg output is now on nomads.ncep.noaa.gov, listed at the bottom of the page. The script name is different to keep separate from current production, and will move back to the production names June 12.
