From The Journal:
TWO EUROPEAN NATIONS recorded their hottest day on record today as the sweltering heat continues in Central Europe.
Ireland may have cooled down (although not for long, seemingly), but high temperatures continue to pulse across the continent. Slovakia, Croatia, and Hungary recorded temperatures in the high 30 and low 40 degrees. Hungary experienced an all-time high temperature of 42 degrees today (107.6 °F), beating the previous 2007 record of 41.9 degrees. The heat was focused on northern Hungary, near its border with Slovakia.
