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.

This is the time of year when I get the absolute worst range: cold temps and all-season tires still on. I'll see the GOM duck into the high 20s regularly, and get actual range into 25 miles for a whole charge. As soon as I put the winter tires on, that'll just back up to 30 or 32 until it gets cold enough that ERDTT starts happening and ruins all good tracking....
