Hi Keith,
For all the 0-180 hour time frames:-
GFS, 4 outputs a day, 00z released around 04:15-05:00, 06z, 10:15-11:00,
12z, 16:15-17:00 and 18z 22:15-23:00.
As for the 180+ time frames, generally about 1 hour after the 0-180's. So
for the 12z run, usually around 17:00-17:30.
Danny.

Out of interest what times do the GFS model update on the internet?
And secondly, there appears to be a varying time between the GFS T+0
to T+8 days and T+9 to T+16 days. I say this as the first lot have
recently changed this morning, whereas the second lot haven't, and
they are showing a very mild longer term ~ hence I'm hoping they will
change :-)
