You want to know the temperature of the snow T0 (guess -10C), the latent heat of melting of water c_l, the heat capacity of snow c, the top area of the dome A, the predicted snowfall depth per hour, and calculate it

In Dallas we get many more ice storms than snowstorms. Once I was given the task of calculating electrical de-icing for a shop-built radar antenna made from plywood ribs and wire mesh skin, about 20 feet in diameter. The objective was to prevent ice formation, which would cause the dish to become a sail. I did some lab experiments with the goal of maintaining 34 deg. F in the wire mesh with a 20 mph wind. I figured it would take at least four large welding generators. My boss asked me how sure I was of my figures. I told him "If I'm a little off and I get the mesh up to 36 degrees, no one will ever know. But if I only get it to 31 degrees, everybody in town will know."

It didn't get installed, and during the life of the radar test program we were ice free, so I'll never know (thank the Lord).

The result will be an enormous, cost prohibitive, number.
