Another vote for weather.gov. The National Weather Service pages are good. No ads, of course, thanks to your/our tax dollars, and the hourly breakdowns, both forecast and past conditions are easy to find and chock full of information - temp, humidity, wind, wind chill, etc.

Quick Forecast, which I just found a link to while looking at it again to make my recommendations, seems to tie almost everything you're looking for together.
