That’s a rarity by mid-June standards, especially for a city often referred to as “hotlanta.” “Atlanta is used to temperatures in the 90s this time of year, but this is already the third latest start for the first 90 degree temperatures in the city,” CNN meteorologist Michael Guy says.

The pattern isn’t forecast to break until early next week as a cold front advances eastward.
