MINNEAPOLIS (FOX 9) - Sunday marked the hottest day of the year so far in the Twin Cities at 99 degrees. That record lasted about 24 hours.

Minnesota hits 100 degrees

What we know:

According to the National Weather Service, parts of Minnesota hit 100 degrees air temperature on Monday.

Officials say it’s the first time the state has had a high temperature in the triple digits in more than four years.

The last time it happened? June 20, 2022. The record high for July 27? We set it in 1931, at 104 degrees.

The National Weather Service said that after an extremely humid start to the day, dew points dropping to around 60 degrees in the afternoon played a big role in the air temperature rising to 100. Drier air warms more efficiently than humid air.

Holy humidity
