Weather Spark used to be my favorite weather website. It had an interactive plot displaying a bunch weather data, historical, forecasted, historical min/max, and historical standard deviations. This was all in a side-by-side pane with a map view that showed radar data and temperature measurements at individual stations, and you could click different stations to see all of their historical data. It was the best interface to view forecasts and get a sense for how the recent weather stacks up against past years, IMO.

I have not seen any other weather site that comes close to it. The WeatherSpark team made a post to explain why they had to drop the old interface, but I forget the reasons now. The new interface is nothing like the old one -- static plots with buttons to switch to past dates / years, similar to Wunderground.
