A weather expert has warned parts of Ireland could hit highs of 30 degrees - just three short of the highest ever recorded.
The mercury hit a record 33.3 degrees in Kilkenny Castle in 1887 which has not been exceeded since. There were some close calls last July when 31.3 degrees was recorded in Armagh and Tyrone.
The current stretch of hot weather is down to a "hot plume" of air coming from the south. It comes as a much more severe heatwave is set to hit England and continental Europe with France potentially seeing highs of 46 degrees.
