I've just added a new page which records snapshots of the 500hpa 12z
forecast every day on the 00z run.
This feature now lets you see how consistent the GFS is at forecasting
today's weather from a period of up to 8 days away. Quite interesting how
the GFS managed to forecast a ridge of high pressure over the UK
consistently since last Thursday but problems with Fabian are evident.
