La meteo

la météo = (short for météorologie) is the weather or weather service. E.g. la météo est pourrie = the weather sucks.
It can also be an adjective, as in les predictions météo = the weather forecast

Météo France is the organization responsible for weather forecasts in France. Ironically, as the weather has been disrupting Roland Garros (the French Open), Météo France recently ordered a new NEC supercomputer that should allow greatly enhanced precision in its forecasts.
