DOWNTOWN — In case you thought the snowy, chilly Halloween that just happened was just a fluke, we’ve got some bad news: Warm weather is officially gone.
The warmest day this week will be Monday — but even then, high temperatures will just scrape the 50s in Chicago, said Jake Petr, a National Weather Service meteorologist.
From there, everything will get colder: Tuesday and Wednesday should hang around the 40s, while Thursday and Friday will be in the 30s. Temperatures will trend below normal later in the week, Petr said.
“I wouldn’t expect necessarily a ‘warmup,'” Petr said, laughing.
The average temperatures for Chicago this time of year are in the 50s.
“We’re right around normal for [Monday], but as we head into the next day, four to five days, things will be mostly below normal,” Petr said.
In comparison, October started out warmer and wetter than normal — then got colder than usual before ending in a record-breaking snowfall on Thursday.
You can blame Alaska for the cold: The far northern state has been “abnormally warm,” Petr said, which leads to cold air coming down from Canada into Chicago.
“We’ve been locked in this pattern for a little while here, and that’s what’s caused all these cold temperatures,” Petr said.
