weather – know which way the wind blows
weather [ air ] [ st ]
Weather prints the local conditions and seven-day forecast most recently reported at the US airport with the three–letter location identifier air. Given a two–letter US state abbreviation st instead,
weather prints a table of air location identifiers known for st.
The arguments are mutually exclusive and case–insensitive. If neither is given, air defaults to location identifier
ewr, designating the Newark, NJ, airport near Bell Labs, Murray Hill.
