avwx metar KHSV --json       # JSON output

Output includes: flight category (VFR/MVFR/IFR/LIFR), wind, visibility, clouds, temperature, altimeter.

TAF (Forecast)

avwx taf KJFK                # Terminal forecast
avwx taf KHSV,KBHM           # Multiple stations
avwx taf KJFK --raw          # Raw TAF text

PIREP (Pilot Reports)

avwx pirep                   # Recent PIREPs
avwx pirep --hours 4         # Last 4 hours
avwx pirep --limit 50        # More results

Includes turbulence, icing, and weather observations from pilots.

SIGMET/AIRMET

avwx sigmet                  # All active
avwx sigmet --hazard TURB    # Turbulence only

avwx sigmet --hazard CONVECTIVE  # Thunderstorms

Full Briefing

avwx brief KHSV              # Complete weather briefing
avwx brief KHSV,KMDQ,KBHM    # Multi-airport briefing

Combines METAR, TAF, and active SIGMETs in one report.

Flight Categories

Category	Ceiling	Visibility	Color
VFR	>3000ft	>5 SM	Green
MVFR	1000-3000ft	3-5 SM	Blue
IFR	500-1000ft	1-3 SM	Red
LIFR	<500ft	<1 SM	Magenta

Common ICAO Codes

Use 4-letter ICAO codes (not FAA LIDs):

• US airports: Add K prefix (HSV → KHSV, LAX → KLAX)
• Alaska: PA prefix (PANC = Anchorage)
• Hawaii: PH prefix (PHNL = Honolulu)
• International: varies (EGLL = London Heathrow, LFPG = Paris CDG)

Data Source

All data from NOAA Aviation Weather Center (aviationweather.gov). Updated every minute for METARs, every 6 hours for TAFs.

Installation

No dependencies required (uses Python stdlib only).
