British Isles weather, September 2015

Pressure remained high (around 1038 mb in NE England at 2400 GMT) on the 27th. Mist and fog patches were widespread early in the morning but soon cleared. A few sheltered areas had a ground frost early in the day and there was some showery rain in the Western Isles during the day. However, for most places the day was a sunny one - away from W parts of Scotland - and also warm in many places. (Fyvie Castle 20.8C, Harris Quidnish 13.7C maximum, South Newington -0.5C minimum, Stornoway 1.4 mm, Jersey Airport 11.2 h.)

Many places in England in particular had some fog patches before dawn on the 28th; most of this soon cleared - except in parts of N Yorkshire - and a mainly sunny day followed. It was, however, rather cloudy across N Scotland; in the sunny regions it became quite warm in the afternoon. Clear skies gave a good view of the supermoon lunar eclipse in many areas in the early hours. (Porthmadog 20.8C, Inverbervie 12.7C maximum, Ravensworth 0.2C minimum, Normanby Hall 0.4 mm, Jersey Airport 11.5 h.)

Fog and low cloud again formed widely by dawn on the 29th under prevailing high pressure (1039 mb in parts of E England at times in the day). The fog was slow to clear in places but another warm, dry and sunny day followed once it did so. Parts of S Ireland, however, remained rather cloud (e.g. 0.1 h of bright sunshine at Cork). Mist and fog again formed widely in the evening, especially over N England and parts of Scotland. (Aboyne 23.2C, Lake Vyrnwy 13.6C maximum, Redesdale Camp 0.5C minimum, Alice Holt Lodge 0.2 mm, Jersey Airport 11.3 h.)

Early mist and fog was widespread on the 30th and was slow to clear over parts of Ireland. There was a widespread ground frost in sheltered parts of Scotland but all places had a dry and sunny day - except across parts of the Northern Isles. Both the highest and lowest air temperatures of the month occurred today (which was widely a warm day) - and both occurred at Braemar. Mist and fog reformed over parts of Scotland and Ireland in the evening. (Braemar 24.0C, Baltasound 12.7C maximum, Braemar -1.3C minimum, Gringley-on-the-hill 0.4 mm, Jersey Airport, Odiham, Yeovilton and Wattisham 11.1 h.)
