Snow tire mileage

Just installed new Blizzak snow tires on my new 2018 Volt and my MPGE on my regular commute to work and back dropped from 120 down to 100.
Is this normal? Not sure if this matters but the temps here in Oregon is still mild 45-55.

I may be hallucinating, but the car actually feels like the tires are sticking to the road.
The interesting thing is the mileage drop is about the same as the the heating drop. If I don't run the heat I can gain almost what I lost on the snow tires.

However when the weather changes and the ground begins to freeze, you will require more heat in the cabin to keep it comfortable.

Up here in Northern Ontario, my range dropped to about 25 mile in the 0F temps. And that was with just enough heat in the cabin to keep me comfortable. I am sure part of the loss was also due to the cold soaked battery.
