2008 - Barometric Pressure & Temperature.

2008 - Dewpoint.

Note Regarding the Relative Humidity and Dewpoint: On October 2nd the Humidity Sensor rose beyond it's normal high and seemed to be stuck at 100% even though the conditions seemed to not reflect that. The Humidity Sensor was adjusted downward by 3%. All readings after that reflect the 3% reduction.
