British Isles weather, September 2018

Pressure was high everywhere on the 28th - close to 1036 mb in W Ireland - as a cold front pushed S'wards, weakening all the time. The front produced little rain - although there were also some overnight showers in N Scotland. Parts of N Ireland, N England and S Scotland had a touch of air frost; away from N Scotland, many inland areas as far S as the Midlands had a ground frost. There was little rain during the day apart from a few showers across N Scotland. It was sunny in Wales and S Ireland with varying amounts of cloud and sunshine elsewhere. (Gosport Fleetlands 18.5C, Dalwhinnie 9.8C maximum, Katesbridge -1.6C minimum, Baltasound 4.2 mm, Aberdaron 10.9 h.)

A further cold front moved S'wards across N Scotland and N Ireland during the 29th while high pressure persisted in all areas. Overnight rain across Shetland spread into N Scotland during the day - with slight falls in N Ireland. There was an air frost in N and Cent England, and in parts of Ireland and Wales; in E Scotland and across Ireland, Wales and England there was a widespread inland ground frost. It was a sunny day across most of England, Wales and S Ireland. (St James Park 18.7C, Salsburgh 9.7C maximum, Katesbridge -3.6C minimum, Cluanie Inn 21.2 mm, Wellesbourne 11.0 h.)

The cold front gradually moved SE'wards on the 30th clearing the SE corner of England after midday. It gave little rain as it moved across England, especially in the S. Ahead of the front, under clearer skies, there was an air frost in E, Cent and S England while in the cloudier areas under the front minimum temperatures were closer to 10C. During the day it was cold, blustery and showery in the north, especially over N Scotland, with hail in places - and snow at the highest levels. There were sunny spells, particularly in E Scotland. After a sunny start in the south, most of England and Wales was cloudy and chilly with a few showers or patches of light rain, chiefly in N and W areas. (Langdon Bay 16.3C, Dalwhinnie 8.7C maximum, Santon Downham -0.9C minimum, Loch Glascarnoch 15.6 mm, Leuchars 7.4 h.)
