Решение с тернарен оператор:

namespace Weather
{
    class Program
    {
        static void Main()
        {
            string weather = Console.ReadLine();

            string print = weather == "sunny" ? "It's warm outside!" : "It's cold outside!";

            Console.WriteLine(print);
        }
    }
}
