In damper areas (and Pittsburgh, PA is definitely a damper area; the top of Laurel Mountain just to the east, which is the western edge of the Appalachian Mountains, is officially a temperate rain forest) - anyway, in damper areas, the humidity is mostly responsible for how comfortable one is when outdoors.
The best way to follow this is with the dew point.
While you can configure the System Tray tooltip to show the dew point temperature, it would be nice if:
One could have, as an option, the number in the system tray represent not temperature, not “feels like” temperature, but the dew point. It isn’t as good for instant measurements, but for tracking changes in the humidity over time, it’s probably the best.
It would be great to be able to see a graph of the dew point over the past few days or weeks right in Weather Watcher.
You know, the historical data display on WeatherBug is not very good. It requires Silverlight which won’t work under FireFox 3, and even in Internet Explorer, the historical display is (a) awkward, and (b) doesn’t work right - when changing ranges, you can’t get it to actually show you the latest data, the graph simply won’t extend to the most recent data when you drag the little sliders.
Having, as an option on the main tab of WW an option to display, say, the last 24 hours of data in 2 hour increments, or the last 3 days in 6-hour increments, or something like that, would be very, very handy.
