British Isles weather, June 2015

On the 28th two bands of frontal rain crossed the British Isles from the W - the final one along a cold front clearing Kent in the evening. As the rain moved E'wards the rainfall amounts tended to decrease. Most places had some sunny period s- but the best of the sunshine was to be found in S Ireland and W Wales. (Gravesend 22.9C, Fair Isle 12.4C maximum, Lerwick 6.7C minimum, Eskdalemuir 21.8 mm, Cork Airport 10.6 h.)

Pressure rose from the SE on the 29th, rising above 1020 mb across most of England by 2400 GMT. It was a sunny day in Cent S and SE England and in East Anglia - it was also warm in this area away from coast. Elsewhere, skies were cloudier - and quite dull in much of Ireland and W Scotland. There were outbreaks of rain and drizzle in these dull areas. (Gravesend 26.7C, Lerwick 13.3C maximum, Aboyne 6.0C minimum, Kinlochewe 11.8 mm, Wattisham 14.8 h.)

Warm air from the near-continent moved into England and the Channel Islands 30th, leading to maximum temperatures of 28-30C in many parts of England, and at Jersey St Louis 32.9C made it the hottest June day since records began over 120 years ago - just 3 degC short of the highest figure ever recorded in the Island. In the evening the heat led to thunderstorms that spread from the Channel Islands into Cent S England. [Note that at some places as far N as Aviemore and Tiree the maximum temperature at 0900 GMT/1 July was higher than the 06-18 GMT maximum on 30 June. However at Guernsey Airport these two values were 29.4C (maximum) and 16.5C (0900 GMT/1st temperature).] Scotland and W Ireland were cooler with outbreaks of rain or drizzle - although falls became more scattered and weaker as the day developed. (Jersey (St Louis) 32.9C, Lerwick 13.3C maximum, Frittenden 7.5C minimum, Stornoway 17.2 mm, Waddington 15.7 h.)
