Just a quick tip, in visual studio, there's a built-in feature to convert json to C# model.

You can find it in Edit\Paste Special\Parse Json as classes

About your question, your model is invalid, try this.

public class WeatherItem
{
    public City city { get; set; }
    public string cod { get; set; }
    public float message { get; set; }
    public int cnt { get; set; }
    public List[] list { get; set; }
}

public class City
{
    public int id { get; set; }
    public string name { get; set; }
    public Coord coord { get; set; }
    public string country { get; set; }
    public int population { get; set; }
}

public class Coord
{
    public float lon { get; set; }
    public float lat { get; set; }
}

public class List
{
    public int dt { get; set; }
    public Temp temp { get; set; }
    public float pressure { get; set; }
    public int humidity { get; set; }
    public Weather[] weather { get; set; }
    public float speed { get; set; }
    public int deg { get; set; }
    public int clouds { get; set; }
    public float rain { get; set; }
}

public class Temp
{
    public float day { get; set; }
    public float min { get; set; }
    public float max { get; set; }
    public float night { get; set; }
    public float eve { get; set; }
    public float morn { get; set; }
}

public class Weather
{
    public int id { get; set; }
    public string main { get; set; }
    public string description { get; set; }
    public string icon { get; set; }
}
