A site that provides us with interactive weather charts, WeatherSparks.com is a great resource for getting multiple forecasts for any single location, and to compare everything with any other city in our country, or even with any other city in the world.
That is possible because Weather Spark gets its information from weather stations spread throughout the Earth. The data is always presented to you as a series of easy-to-understand graphs, and if you live within the US you will be able to get up to three local forecasts at the very same time (that number is lowered to two forecasts if you are not in America).
In any case, the reports generated through Weather Spark can always be printed and consulted when you are offline. Or stuck somewhere anybody can see them.
Searches can be carried out both by the name of the city you live in (or are interested in, either because you have relatives there, or you are giving it a visit soon), and by ZIP code.
