CHICAGO (WLS) -- If you still need to mail that Christmas gift, you might be in luck.
Most Chicago post offices closed early Wednesday, but the Main Post Office at Harrison will close at 5 p.m.
If you must get your gift there by Thursday, remember to ask for Priority Mail Express, cross your fingers and hope for good weather.
The U.S. Postal Service says it will be delivering on Christmas Day, but only mail with specified Christmas Day delivery.
The post office will also be open the Friday after Christmas, New Year's Eve and the day after New Year's Day.
