Speaking of weather, most all weather apps and sites suck. They either take too long to load (waiting for www.weatherunderground ) or they give out false readings. It's currently 67F where I am, but my weatherunderground site says it's 80F. I googled why this is and came upon some op-ed articles explaining why. It's a bit too technical to go into here. BTW, the Weather Channel owns Weatherunderground.
You have to pick your weather station if you want to get somewhat accurate data on weatherunderground, keeping in mind that the "weather station" could be in somebodies backyard. It may not be set up right, and may not be properly maintained.
