Forecast temperature anomalies in Celsius for the next 5 and 10 days. The forecasts are generated by comparing reanalysis data from 1981 - 2010 with the latest run of the
Global Forecast System (GFS) model.
The charts are updated 4 times each day at approximately 05:30, 12:30, 17:30 and 22:30 GMT.
The lower grid resolution of the reanalysis data means local variations may not be well identified.
