Why not just use ForecastAdvisor?
ForecastAdvisor uses the National Weather Service's Digital Forecast Database for its forecasts. This is the National Weather Service's most accurate and detailed forecast. Our clean, easy-to-read format is easy on your eyes, and you can keep tabs on who provides the most accurate forecasts for your city.
The National Weather Service's Digital Forecast Database is not available via a web page, but it's used as the basis of the National Weather Service's weather.gov site. Because weather.gov doesn't provide an easy way to link to a specific city's weather forecast when you know only the ZIP code, if you want to continue on, you'll need to enter in your city or ZIP code on the NWS main page.
