Oh, that's great that he show up on time. The timing is getting into him and I think it's cold and snowy, that's why he came knowing there's food for him here.
Is there a way to put a shade or shelter over the entrance of the hot house? So that the snow won't be blown in that much?
The other thing is while he's eating, sit with him and keep talking to him and praise him 'good boy'.
Have you tried while he's eating, you leave him alone with the sliding door closed and see how he reacts being alone there. See if he is restless or scratching the door to get out. If he stays calm, chances are he can be locked in. Otherwise he'll hurt himself trying to bash through the glass door. But then again, it's a risk you'll be taking and this might freak him out.
Every step must be a careful step. Inch his hot house closer and closer to the door and it's a little troublesome to bring in the hot house evert time during feeding but it may help.
