✈️ METAR parser
===============
Parse METAR information into structured JavaScript object. The structure of the returned object is closely related to the [API response of CheckWX](https://api.checkwx.com/#metar-fields).
Installation: `npm install aewx-metar-parser --save`
Functionality
-------------
This METAR parser returns the following parts of a METAR string:
* ICAO code
* Date / time
* Wind speed (in kts, mps) & direction
* Visibility (in meters and miles)
* Weather phenomena
* Clouds
* Temperature (in °C & °F) & humidity
* Barometer pressure (in InHg, kpa & mb)
Code example
------------
```javascript
'use strict';
const metarParser = require('aewx-metar-parser');
const metarObject = metarParser('KSFO 070121Z 19023KT 1 1/2SM R28R/6000VP6000FT -RA BKN004 BKN013 OVC035 15/12 A2970 RMK AO2 T01500122 PNO $');
```
…returns:
```javascript
{
raw_text: 'KSFO 070121Z 19023KT 1 1/2SM R28R/6000VP6000FT -RA BKN004 BKN013 OVC035 15/12 A2970 RMK AO2 T01500122 PNO $',
