Your JSON isn't in the correct format for the arrayToDataTable method to
use. Try this:
var rows = [['Label', 'Value']];
json = JSON.parse(json);
rows.push(['TempOut', json.TempOut]);
rows.push(['FeelsLike', json.FeelsLike]);
rows.push(['HumidityOut', json.HumidityOut]);
rows.push(['WindAvg', json.WindAvg]);
rows.push(['WindGust', json.WindGust]);
rows.push(['Rain', json.Rain]);
rows.push(['AbsPressure', json.AbsPressure]);
var data = google.visualization.arrayToDataTable(rows);
