CHICAGO (CBS) — This weekend might be the coolest ever in July for the Chicago area, with low temperatures dropping into the low 50s on Saturday night.

CBS 2 Meteorologist Megan Glaros reports Friday’s high temperature of 78 degrees will be as high as things will get, as a cold front moving through Friday afternoon and evening will mean a very cool Saturday and Sunday.

Saturday’s high temperature is expected to be about 70 degrees, barely above Chicago’s lowest recorded July 27 high temperature of 69 degrees, seen in 1981, according to the National Weather Service.

The low will drop to about 52 degrees Saturday night, which would match the record set in 1985.

Sunday won’t be much warmer, with a high of about 74 degrees. The lowest recorded July 28 high in Chicago was 66 degrees, also in 1981.

Temperatures should be up to the high 70s on Monday and Tuesday, and back in the 80s by Wednesday.
