Parsing Soap request in XML C#

I am trying to get the values out of the Soap request I made. It comes in an XML format, for some reason I cant get just the values. How can I? How would I get just maximum and minimum temperature values? 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WeatherData.Weather_Gov;
using System.Xml.Linq;

namespace WeatherData
{
    class Program
    {
        static void Main(string[] args)
        {
            ndfdXMLPortTypeClient client = new ndfdXMLPortTypeClient();


            weatherParametersType weatherParams = new weatherParametersType();

            string weatherData;

            decimal lat = (decimal)(31.5452);
            decimal lon = (decimal)-109.468;

            weatherData = client.NDFDgenByDay(lat, lon, DateTime.Now.ToUniversalTime().AddDays(-1), "2", "e", "12 hourly");

            var myElement = XElement.Parse(weatherData);

            Console.WriteLine(weatherData);
            Console.ReadKey();
        }
    }
}

This is the output what I got in my console application window.

How do I pull out, for example, the Daily Max Temp?

  <temperature type="maximum" units="Fahrenheit" time-layout="k-p24h-n1-1">
      <name>Daily Maximum Temperature</name>
      <value>94</value>
  </temperature>

So once you've parsed your XML to an XElement, you use the LINQ to XML API to query it:

var max = element.Descendants("temperature")
    .Where(e => (string)e.Element("name") == "Daily Maximum Temperature")
    .Select(e => (int)e.Element("value"))
    .Single();

var min = element.Descendants("temperature")
    .Where(e => (string)e.Element("name") == "Daily Minimum Temperature")
    .Select(e => (int)e.Element("value"))
    .Single();

If you had multiple values, then you could iterate through a sequence of integers:

var maxTemps = element.Descendants("temperature")
    .Where(e => (string) e.Element("name") == "Daily Maximum Temperature")
    .SelectMany(e => e.Elements("value"))
    .Select(e => (int)e);
