Weather Challenge Begins Soon

I am going to start writing about the Weather Challenge on this website for the foreseeable future. I want to write out some of my thinking without giving my numbers away, so if you are in the challenge please feel free to read this, but don't expect to get actual numbers. For now, I am just going to jot down the MOS numbers for the next couple of days to see some trends and look at actual numbers compared to the forecast numbers. Doing this gives you a little hint as to how well MOS is doing for this forecast location with the current airmass. However, if a different airmass moves into the area the first day of the forecast, doing this can often cause you to react incorrectly. So don't take the trends as a golden rule, it doesn't always work...but it can be handy. The first city is Charleston, SC:
