The UK's Scorcher Weekend

From the weather diary on this website:

The 28th was another generally dry day due to an anticyclonic ridge extending from the N over much of the British Isles. This ridge meant a mostly cloud-free start to the day - although there were some showers over SW England before dawn - and an air frost in parts of N Scotland; however, in parts of S Ireland minimum temperatures remained close to 10C. Early cloud in NE England soon cleared - although it returned in the evening - and away from S Ireland most places had a sunny day with little cloud. The afternoon and evening also brought cloud to N and E Scotland (Lee-on-Solent 24.4C, Altnaharra -3.5C, Isles of Scilly 1.8mm, Kinloss 14.4h.)

Generally dry and anticyclonic conditions continued into the 29th. Parts of Cent and N Scotland had an air frost under clear skies, although much of E Scotland and E and Cent England had a cloudy start to the day. Thunderstorms affected the Channel Islands overnight and into the morning. Showers also affected Kent and parts of W Ireland. In most places the early cloud in the E soon cleared although W Ireland and NE Scotland remained rather cloudy during the day. (Lee-on-Solent 23.7C, Aviemore -0.9C, Pembrey Sands 0.8mm, Kinloss 14.4h.)

So, the scorcher weekend saw an absolute high of 24.4C in all of Great Britain ... and it still dropped below freezing in Scotland!
