###

			pushEvent body

###

###
exports.temperatureOverThreshold = ( city, tempThreshold ) ->
	getWeatherData city, ( err, resp, body ) ->
		if err or resp.statusCode isnt 200
			log JSON.stringify body
		else
			#If temperature is above threshold
			if body.main.temp_max - 272.15 > tempThreshold
				pushEvent
					threshold: tempThreshold
					measured: body.main.temp_max - 272.15
