Query regarding fog in forecast

Just a bit puzzled why I always seem to get fog in my forecasts when it virtyually never happens at least at this time of year. I have tried lowering the fog setting and now have it at 25 but it still often says fog. I read that I can turn off the fog routine during a run with an interrupt or something but if I set the fog routine to 0 does that accomplish the same thing permanently?

Well I just answered one question setting fog sensitivity to 0 does seem to turn it off.

I am still puzzled as to why WXSim seems to suggest so much fog for my location, I did try lowering the sensitivity but it seems to have to go to extremely low before fog disppaeras from the forecast.
