Notes: 1.  Rain Day = 1mm (0.04 inch) or greater rain during the 24 hour day.

            2.  Frost Day = The minimum temperature was 32°F (0°C) or below at sometime during the day.

            3.  Wind run is a measurement of how much wind has passed a given point in a period of time.  A wind blowing at                         3mph for an entire hour would give a wind run of three miles.
