Most of the data used n models are collected by weather balloons. a weather balloon will collect temperature , dew point Temperature which we can find the relative humidity from, the pressure as it goes up into the atmosphere. By tacking the balloon and where it is going, we can also calculate the winds at different levels. Weather balloons are launched twice a day at about the same time all around the world. The data collected are then feed into a computer and the forecast models will come out. But weather balloon are not the only data being from into models, other things like surface weather station reports, ship reports, air plane soundings, satellite sensor data, and wind profilers data are just some of the other data used too.

In addition to what UALog writes, I would like to add that the data from only one country isn't enough to draw the larger picture of the present weather since winds and clouds don't stop at the borders.
It is the World Meteorological Organization (WMO), a division of the United Nations, that is in charge to collect and redistribute worldwide observations. Little known, the United Nations is much more than a building in New York. What would we be without the ICAO that organized civil aviation, the IMO that takes care of seafarings and the WHO that works at preventing worldwide pandemics?

the kinds of data that are used to make weather maps and forcasts are ussually not anything you would know because its normally figured out by scientists that are looking in the sky, finding answers anyway they can and some of the data is that you can use warm water to make a forcasts and rocks.
