It is surrounded by the Appalachian mountains. In anticipation of issuing official public forecasts from Morristown, forecasters have regularly prepared a practice zone forecast product for all of our counties. This sensor difference should have little effect on the data comparison. It will be interesting to see how and if the temperature averages at Chattanooga change with this new technology. A linear regression was done using Quattro Pro with the high and low temperatures each month to detect a possible pattern.
R is the correlation coefficient.
This shows the strength of the correlation between the two groups of data. There are no Class A observation sites in the mountains of southwestern North Carolina and no specific forecast points. So the elevation for which the forecast is made is vague. A customary solution is to target the elevation near which most people live. This is roughly 3000 feet in the mountains, and is conveniently halfway between their peaks and the Tennessee Valley's elevation.
