NAME
weather - command-line tool to obtain weather conditions and forecasts
SYNOPSIS
weather [ options ] [ alias1 | search1 [ alias2 | search2 [...]]]
DESCRIPTION
This command-line utility is intended to provide quick access to current weather conditions and
forecasts. Presently, it is capable of returning data for localities throughout the USA and some select
locations globally by retrieving and formatting decoded METARs (Meteorological Aerodrome Reports) from
NOAA (the USA National Oceanic and Atmospheric Administration) and forecasts/alerts from NWS (the USA
National Weather Service). The tool is written to function in the same spirit as other command-line
informational utilities like cal(1), calendar(1) and dict(1). It retrieves arbitrary weather data via
precompiled correlations or custom-tailored aliases (system-wide or on a per-user basis).
Behavior can be determined by command-line options and specification of zero or more location aliases and
search terms.
Aliases are defined in weatherrc(5) files, as a convenient means of grouping URIs together using a short
name. Specifying multiple aliases or location search terms on the command line causes the utility to
output data for each, as if it had been invoked multiple times. If none are specified, then an alias of
default is checked for a defargs option and any alias names listed within it (comma-separated) are
applied instead.
Searches utilize location correlation sets in INI-style text files named airports, places, stations,
zctas and zones. A precomputed copy is distributed with the source, but can be rebuilt from updated data
sources as needed by placing them in the current working directory and running with the --build-sets
option (see the comments at the top of any location correlation set file for instructions on where to
find updated data sources). Positive search results are cached and sourced as aliases on subsequent runs
for as long as the correlation sets remain unchanged, and are cleared automatically once the correlation
sets are updated.
Retrieved data is also cached automatically for a short period of time, adjustable with the cacheage
configuration option or --cacheage command-line option. This helps throttle load against NOAA/NWS
servers in case the utility is repeatedly re-run requesting the same data, but can be overridden with the
cache_data configuration option or --no-cache-data command-line option.

EXAMPLES
weather
View output for the default alias, if one has been defined (otherwise display usage/syntax similar
to --help)
weather rdu
Display weather conditions at the airport with IATA/FAA code RDU.
weather --info raleigh
Show a list of FIPS codes for United States Census Bureau places containing the word raleigh (or
the proximity information if only one match was found).
weather "^ral[ie]{2}gh city.*nc$"
Get the current weather conditions from the nearest station to the Census place name matching the
regular expression provided.
weather -fv fips3755000
Get the full decoded METAR from the nearest station, and the forecast data for the nearest zone to
the Census place with FIPS code 3755000 with no special filtering or formatting.
weather --forecast --no-cache-data 27613
Ignore any recent cached METAR or forecast data and display fresh output for the nearest station
and zone to the Census ZCTA (essentially USPS ZIP code) 27613.
weather home work
Show current conditions for both the home and work aliases in that order.
weather 35.878573,-78.727813
weather 35-52-43n,78-43-40w
weather "35-52n, 78-43w"
Display weather conditions for the nearest station to an arbitrary set of global coordinates in
latitude,longitude order either in decimal format or degree, degree-minute or degree-minute-second
formats, optionally using signed or cardinal hemisphere designations with or without spacing.
Note that the cut-off for maximum acceptable distance is hard-coded at 0.1 radians (roughly 637km
or 396mi).
INPUT FILES
weather may additionally obtain configuration data from a system-wide configuration file, a per-user
configuration file, and a local directory configuration file. The file format and configuration options
are described in weatherrc(5). They are aggregated in the following order:
/etc/weatherrc or /etc/weather/weatherrc
the system-wide configuration
~/.weather/weatherrc or ~/.weatherrc
the per-user configuration
./weatherrc
the local directory configuration
