My outdoor thermometer is still showing 10 below like it did most of the night. Nearest NWS stations show -15 to -17 overnight but warming up. In the temperature range above freezing this mechanical thermometer tends to agree with those weather stations 25 miles east and west. Between about zero and 32 it tends to be 4 degrees colder. then below zero it tends to show 3 or 4 degrees warmer.
