SQL server convert datetime using LINQ - sql

Question

I have the query I need in SQL server but I'm using Entity Framework and would like the same results using LINQ. Here is the SQL:
select convert(varchar, date_recorded, 12), MAX(outdoor_temp), MAX(wind_speed)
from weatherdata
group by convert(varchar, date_recorded, 12)
order by convert(varchar, date_recorded, 12) DESC ;
This converts my datetime column to a correct format that allows me to group properly. Basically I need to be able to convert my SQL datetime to yymmdd format.
Many thanks

class Program
{
static void Main(string[] args)
{
var entries = new List<Entry>()
{
{new Entry { Date = DateTime.UtcNow, Outdoor_Temp = 10, Wind_Speed = 5 }},
{new Entry { Date = DateTime.UtcNow, Outdoor_Temp = 5, Wind_Speed = 10}},
{new Entry { Date = DateTime.UtcNow.AddDays(-1), Outdoor_Temp = 15, Wind_Speed = 7}}
};
(from e in entries
group e by e.Date.ToShortDateString() into g
select
new
{
StringDate = g.Key,
MaxWind_Speed = g.Max(entry => entry.Wind_Speed),
MaxOutdoor_Temp = g.Max(entry => entry.Outdoor_Temp)
}
).ToList().ForEach(Console.WriteLine);
}
public class Entry
{
public DateTime Date { get; set; }
public int Outdoor_Temp { get; set; }
public int Wind_Speed { get; set; }
public override string ToString()
{
return string.Format("Date : {0}, Outdoor_Temp : {1}, Wind_Speed : {2}", Date, Outdoor_Temp, Wind_Speed);
}
}
}
