In case anyone is curious, my favorite weather website is Weather Underground. I really like to go there when there is a possible Tropical Storm or Hurricane headed our way because it shows me the computer models and detailed forecasts.
I also occasionally check www.weather.com for the hour by hour forecast. For example, tomorrow at 11am there is a 70% chance of rain. They are also charting the temperature throughout the day now, so that is a nice feature.
Day to day, my default is just to look at my google homepage or type "weather 77380" into my handy google search box and it pops up in the search results!
