You're making the assumption that winter snowpack has a dramatic effect on farming success. Sure, it helps fill the aquifers when it melts, but farmers depend on rainfall (at least in the US) as much as they do on irrigation. Heat also makes it hard for crops to grow successfully, regardless of how much water they get through irrigation.
