RE:RE:RE:From Russia with love! This will slow down production. For Feb/March long-range forecasts, the US national weather service updates in the middle of the month. Next update is Jan 16th.
ECMWF is also a place to look, forecasts are for each future week and you can select the date the forecast was done. I don't really spend that much looking at the weather, so I usually just look at the US weather service forecasts.
