Temperatures reached 12C in Reigate yesterday and stayed above 10C overnight. This is very warm for December! The reason is shown in the latest NOAA high resolution satellite taken this 10.15am Sunday. The bank of cloud shows the warm funnel of air brought from the SW by a vigorous jetstream. North of this stationary front are blobs of cumulus cloud shown catching the sunshine. South of the front is a big High pressure giving Spain clear conditions. Also, spot the snow on the Pyrenees. The jetstream turns South over Europe and is bringing cold conditions over places like Greece where snow has fallen over Mount Pelion on the Aegean coast.
