It has been a record 290 days since Chicago's last measurable snowfall of 0.3 inches on March 4 but at 6:30 pm the city's official observation site at O'Hare International Airport officially recorded the city's first measurable snow of the season recording 0.1 inches.
This delayed first measurable snowfall has established two new records for the city.
The latest first measurable snowfall in a season... the old record 0.3 inches on December 16, 1965
The longest snow-free period from the last measurable snow in spring to the first measurable snow in the fall... the old record 280 days from March 1-December 5, 1994.
