        xmlHttp.setRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:221.0) Gecko/20100101 Firefox/31.0");
        xmlHttp.send( null );
        resp = xmlHttp.responseText;

    return resp;
}

The web address has been updated to use https://

For Android replace getCurrentConditions() function with following

function getCurrentConditions(lat, lng) {
var url = "https://forecast.weather.gov/MapClick.php?lat=" + lat + "&lon=" + lng + "&FcstType=json";
var resp;
var xmlHttp;
 
    resp = "" ;
    xmlHttp = new XMLHttpRequest();
 
    if(xmlHttp != null)
    {
        xmlHttp.open( "GET", url, false );
        xmlHttp.setRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:221.0) Gecko/20100101 Firefox/31.0");
        xmlHttp.send( null );
        resp = xmlHttp.responseText;
    }
 
    return resp;
}

The main post has been updated to include the following line in the function to set the User-Agent request header.

xmlHttp.setRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:221.0) Gecko/20100101 Firefox/31.0");
