[wxqc] Vantage-Pro Dew Point Calibration Question

[Steve Hatchett]

We had a fog event that lasted quite a few days. It was extremely foggy, and
everything was dripping wet. I was convinced it could get no foggier or more
saturated than it was. But my VP2 refused to go above 99%. I was somewhat
disappointed, and literally on the verge of bumping the calibration up by a
percent when it proceeded to get even foggier and more saturated than I
thought possible and the station began reporting 100% humidity. It stayed
that way for several hours until a system moved through and ended the
inversion. Now I'm glad I didn't do the calibration adjustment.
