Saturday was a very, very cold day as the thermometer so very slowly managed to get above freezing for just over an hour with a maximum of only 0.6C at 13.27, being a significant 7.3C below the 39-year average, before dropping back down to -0.6C at 14.30, then continuing further down to a minimum of -3.5C at 18.30 and hovering around that point until 22.00. At that time thin cloud was observed beginning to cover the moon that heralded the major change as by 22.30 the temperature had risen to -1.0C at 23.15 and +0.6C at 01.30 Sunday. By 08.00 on Sunday the thermometer read 4.2C. A very brief rain shower had deposited 1.4mm at 02.00.
Sunday dawned damp and dull with very low cloud shrouding the Marlborough Downs and Savernake Forest limiting visibility to around 500m. The air flow will today vary between southwest and southeast later in the day as a deep depression meanders towards us along the English Channel, but again very light.
