Latest Forecasts and Weather Maps
NB: NW3 is an observation site, which means it cannot provide its own detailed forecasts, and therefore uses those that are externally produced.
Proper forecasting relies on running sophisticated computer models on large supercomputers using data from a wide array of sources, including land-based observations sites like this one.
A full discussion of this can be found here.
Below are the latest forecasts and weather maps provided by external weather services.
