GEFS Mean Anomaly Charts

These charts show the average (mean) of all GEFS ensemble members as an anomaly, meaning how different conditions are expected to be compared with normal. Precipitation, 500mb height and 850hPa temperature anomalies help to highlight developing patterns, such as a blocking high, an unsettled spell or a cold plunge, over the UK, Europe and the Northern Hemisphere.
