Another regional jet crash

I wonder what part the snow played in keeping this aircraft from being fully engulfed in flames after it flipped and the wings were sheared off. The lack of a catastrophic post-crash fire is what prevented this incident from taking many lives. Most commercial jets land with about 45 mins of fuel remaining onboard. When skidding down a runway, you want to be as far away from the fuel as possible. Whatever fire ensued, it was both isolated and quickly contained.
Isn't fuel stored in the wings? Maybe that had something to do with it?
