Installation

npm install weather-gov-graph-parse

Usage

Require the module.

var gp = require('weather-gov-graph-parse');

Fetch and parse the weather graph.

gp(pos.latitude, pos.longitude, function(err, data) {
	// data is an array of data points
});

Or fetch and parse the weather graph, promises style.

gp(pos.latitude, pos.longitude).then(function(data) {
	// data is an array of data points
});

Data

The data variable that is returned is an array of data points. Each data point has the following structure. All fields are always present unless otherwise noted.

{
	// The date of the prediction data point.
	date: [date]

	// The predicted temperature.
	temperature: number

	// The predicted dew point.
	dewPoint: number

	// The predicted heat index, if available. This may be 'null' if no heat
	// index is available. The weather.gov weather graph assumes that if no
	// heat index is available, it is the same as the temperature.
	heatIndex: number

	// The predicted wind speed.
	windSpeed: number

	// The predicted wind direction. This will be either 'N', 'NNE', 'NE',
	// 'ENE', 'E', 'ESE', 'SE', 'SSE', 'S', 'SSW', 'SW', 'WSW', 'W', 'WNW',
	// 'NW', or 'NNW'
	windDirection: string

	// The maximum predicted wind gusts, if available. This may be 'null' if
	// no gusts are predicted.
	gust: number

	// The predicted sky cover, in percent. This will be between 0 and 100.
	skyCover: number

	// The predicted precipitation potential. This will be between 0 and 100.
	precipitation: number

	// The predicted relative humidity. This will be between 0 and 100.
	relativeHumidity: number
