Howard et al: Pilots get their weather forecasts from the NOAA National Weather Service thru the FAA and from some private sources. These forecasts are prepared according to ICAO and FAA regulations and requirements.
Observations can come from a variety of sources; however the FAA sets the rules, regulations and standards for aviation. The FAA purchases automatic weather observation equipment for major airports in the US and some smaller airports.. Numerous weather observations come from private and public sources beyond the FAA. These are used as input to the NOAA-NWS analysis, forecast and warning system. Observations are exchanged and disseminated including the FAA, radio and TV stations, newspapers, private meteorologists and others including private companies which support all kinds of people, activities, events and organizations who wish to pay for personalized service. ICAO and the FAA (in the US) are the organizations that dictate the units and standards for weather information used in aviation.

I have no clue where they get their weather data from but since its probably from the airport and the National Weather service stations there it is probably provided in English like all the other data they receive. At domestic airports I can not imagine the pilots demanding the ground computers send up the data in English so they do not have to worry about converting it. Nice thought but the pilot was probably just multitasking at the time (reading instruments, sipping coffee, snoozing (haha).
