Chicago is experiencing one of the hottest springs ever: NBC Chicago

Astronomical spring won’t technically last another two weeks, but the city of Chicago just experienced one of the warmest meteorological springs on record.

Meteorological spring runs from March 1 to May 31, and according to the National Weather Service, the month was one of the warmest since records began in 1871.

According to NWS data, the average temperature in the spring was 53.8 degrees, 4.1 degrees above normal. According to officials, the average temperature represents the average between the high and low temperatures on a given day.

That average temperature is the fourth warmest ever recorded, according to officials.

The month of May played a big role in this, as the city saw an average temperature of 64.8 degrees at O’Hare International Airport. That figure is 4.2 degrees above normal and marks the third warmest May on record in Chicago.

These warm temperatures could continue this summer as a La Niña pattern could potentially develop if the El Niño pattern comes to an end. La Niña summers typically bring warmer temperatures to the Chicago area and the rest of the Midwest, with above-average precipitation during those months.

If that pattern continues, the fall season will typically be cooler than normal, according to researchers at the University of Illinois.
