Wednesday afternoon's heat in Yellowknife beat a record set in 1965.
The temperature as measured at Yellowknife Airport reached 24.6°C in the early afternoon, becoming the hottest May 23 on record in the city.
Thursday came nowhere near as close, puttering to around 15°C by the afternoon.
The record daily high for May in Yellowknife was set way back in 1948, when the city's instruments recorded a temperature of 26.1°C.
The record low for May? Minus 22.8°C, set on May 1, 1959. (And don't get too complacent now we're closer to June. The record low for June is -4.4°C, on June 3, 1967.)

Meanwhile, the Northwest Territories has recorded its first forest fire of the 2018 season.
A small one-hectare fire was reported just inside the territory's south-western border, around six kilometres from Yukon on the western bank of the Liard River. It's not clear what caused the fire.
Fire danger is listed as extreme in the Yellowknife and Fort Smith areas, very high in Fort Providence, and moderate in Hay River.
