Brendan Jones, forecaster with MeteoGroup UK, the weather division of the Press Association, said temperatures "significantly" higher than the average for this time of year, by nine or 10 degrees.
Warm air coming from the Mediterranean has caused the good weather, but comes at the expense of western areas of the UK, where the weather front is sitting.
Mr Jones added: "There are some really nasty storms across Scotland however. Strathallan, in Perth and Kinross, recorded 12.2mm of rain in one hour.
"Those sorts of volumes are capable of causing flooding."
Scotland was not the only place affected, with London, Manchester and Milton Keynes experiencing thunder storms.
