Waco area cloud cover predictor

Using NOAA weather maps, some time ago I made a little online Waco area cloud cover predictor, which is now hosted on a better server than before. It shows data for about a week ahead of time (unlike the otherwise superior clear sky clock), every couple of hours, and it shows a mini map of the area. The numbers are percentage cloud covers. My experience is that small numbers are overestimated--about 20% on the map equals to the sky looking clear.
