We have an electric sign for our building, and one of the display options is weather. The sign company uses Yahoo Weather as its data source. Several of us have noticed a large discrepancy between the reading on the sign, the temperature as indicated on a close by thermometer, or by our car indicators. Can vary by as much as 10-15 degrees. This begs the question, how does one find out the location of the temperature sensor used by Yahoo Weather for its listed locations.
