Weather.gov U.S. Current Weather Conditions

Get U.S. location specific current weather data from Weather.gov.

WGOVCWC(SID) queries the XML Feeds of Current Weather Conditions as
provided by NOAA's National Weather Service (http://www.weather.gov), and
returns a struct containing current weather conditions for the area
specified by the corresponding four char SID(s) (Station ID(s)).

Data is available only for a limited number (about 1,800) of locations
across the United States and U.S. Territories. To determine the four char
Station ID(s) of the relevant location(s) and for more information, visit
http://www.weather.gov/data/current_obs/.

The input argument SID can be a single Station ID, or a char or cell
array of Station IDs.

Data is acquired in XML format, after which it is converted into a struct
using the xml_parse function. This function is available in the XML
Toolbox by Marc Molinari on the MATLAB Central File Exchange (File ID
4278).

EXAMPLES:

Example 1: Using a single SID.
wgovcwc('KNYC') returns a 1x1 struct containing fields (among others):

location: 'New York City, Central Park, NY'
observation_time: 'Last Updated on Mar 13, 5:51 pm EST'
weather: 'Fair with Haze'
temp_f: 57
relative_humidity: 78

Example 2: Using a char array of three SIDS.
wgovcwc(['KNYC';'KJFK';'KHPN']) returns a 3x1 struct.

Example 3: Using a cell array of three SIDs.
wgovcwc({'KNYC';'KJFK';'KHPN'}) returns a 3x1 struct.
