The mercury has climbed above 30 degrees in recent days, and a final peak of 31 degrees will follow on Friday. But then it’s over quickly: on Sunday the temperature drops to 22 degrees, and the nice weather won’t return until June 10. Weatherman David Dehenauw explains why 30 degrees in May is not that unusual, how sharply it will cool down soon and what the chances are that the summer of 1976 will have an encore after 50 years.
