Among the little goodies I have on this website (and really never mention or link to) is Weather Plotter. Every hour, 24/7, this program goes out and gets the current conditions from all the official reporting spots in Connecticut and other areas of interest to me.
Weather Plotter does just what its name implies. To website visitors, it’s pretty versatile. You can set the time span and parameter you want plotted.
Since West Palm Beach is one of the cities I archive data for, it is possible to plot the barometric pressure over the last few days and see Hurricane Frances. A hurricane is an area of very low pressure and Frances shows in the plot.
What’s even more impressive is to see the hurricane in the context of a month.
