The Met Office Chief Scientist Professor Dame Julia Slingo OBE FRS reflected on this summer's weather in her latest blog commenting that "seasonal forecasts for this summer suggested that temperatures and rainfall would be near normal. However, as the season progressed all the leading models around the world failed to capture the signal for unsettled weather over the UK".
The weather in September looks set to be much more settled than the previous 4 weeks.
The Met Office Outlook for Monday 7 Sep 2015 to Wednesday 16 Sep 2015 notes: "… the settled conditions should become established across all parts, with some cool misty starts followed by dry and fine days. Temperatures will be close to normal and it will feel pleasantly warm in the sunshine and gradually trend upwards…"
The Met Office Outlook for Thursday 17 Sep 2015 to Thursday 1 Oct 2015 notes: "…a trend towards a northwest, southeast split, with the southeast holding on to the best of the drier weather, although with occasional unsettled spells developing here, while the northwest sees more regular outbreaks of rain and strong winds. Temperatures will be generally close to average…by the end of the month there is a small chance of some more settled warmer conditions becoming established again".
The Weather Network say that: "September looks likely to see high pressure dominating at times, bringing much of the UK some dry and settled weather… There will still be some unsettled weather, particularly across north-western areas later in the month, but overall September is shaping up to be drier than average".
