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.

I wish I waited to put them on but I got a good deal.
I wonder if the tire millage will get better once the ground gets colder and the tires start to harden?
That seems reasonable. As the tires harder the rolling resistance decreases thus giving a slight (if even noticeable) increase in mileage.
