Jorge,
I work for the National Weather Service and I suggest visiting www.weather.gov
You can enter your city or zip and you will be taken to the proper weather forcast office web site serving that area. Once at that site you can get the latest forcast. I am not sure if all individual sites have the same info but I know I just checked my office site and I was able to link to "model data". Model data is the raw data that the Meteorologist use to make the forcast. I believe there is more info than you care to look at.
There are also links to contact people for more info.
Remember the NWS is your federal government working for you. If you have a question please contact your local office.
Hope this helps
Dave
