GEFS: 35-day 10 hPa 60°N [U]

Oct 24th: Problems with NOMADS are currently preventing this site updating.

The new GEFSv12 now features a 35-day run every day at 00Z. Shown here is the output from the previous day’s run, due to the time taken for the data to appear on NOMADS.

Note that, because of the length of the forecast, systematic model biases are more likely to impact the output. These are not accounted for here.
