The extreme cold freezing over Chicago won't stop United States Postal Service employees--but you can give them a break.
The postal service says mail carriers will attempt to deliver for every customer, but if you don't need your mail delivered right away, you can request to put a hold on your mail.
The parcels will be held at your local post office until you're ready to receive it.
"Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds," the postal service's unofficial motto reads.
Admirable--but it's going to be really, really cold Wendesday. So much so that Illinois Gov. J.B. Pritzker issued a disaster proclamation for the entire state as Chicago prepares to see the coldest day on record this week.
So, if you don't need that mail right way, consider giving them a break.
The USPS website has more information on how to do that.
