I have heard of the temperature mechanism you discuss, but I have no
knowledge of the details of the airport temperature readings.  Weather.com
gives the past two nights temperatures for Moscow at 12 and 10 F., new
record lows by a wide margin.  But I had 6 F. and 7 F those two nights,
though I do live in a "draw" as some call it, so cold air might settle into
the area where my thermometer is located, as you described.
