  • Temperature and barometer data recording started on January 28, 2000.   Wind and rain data started on October 23, 2000.   Relative humidity data was added on September 30, 2001. Therefore, there is no wind chill data prior to October 2000 and no heat index data prior to September 2001.

  • Graphs for more than a few months may take several seconds to be created. Please be patient.
