With more thin cloud on Sunday than the previous the maximum temperature was down on Saturday peaking at 18.1C at 13.25. Thicker cloud arrived on the weather front in the afternoon that halted any further increase,the peak being 1.0C below my 40-year average. Around 18.30 there was a very brief, light shower of drizzle, not measurable. It was a much milder night with a low of 11.2C logged at 07.20 early Monday.
The sun was weak after sunrise due to thin cloud on the eastern horizon but by 08.00 had risen above that and gained in strength to shine strongly.
The jet stream for the past three days has been looping to the north of the UK thus allowing the warmer air to arrive as the high pressure developed. However, the centre has relocated towards Scandinavia and grown, in area that has meant the air stream change from west to northeast, which will continue for the next few days.
