A common misconception resurfaces as temperatures drop: cold air makes people sick. Despite old sayings like “wear a coat, or you’ll catch a cold,” the truth is that frigid air does not transmit viruses.

High temperatures on Thursday rose above 10° for the first time since Saturday. This does not mark the end of this bitterly cold stretch though. Friday morning will once again have air temperatures near -10° with a wind chill in the 20s below zero.
