Just checked the elevation of Alturas, according to Wikipedia it is over 4300 feet. My parents are in Oak Run, CA at about the same elevation. They will get heavy snow that will last the entire week or more on the ground, even after it has been plowed. They have spent 17 straight days without electricity.
I live in the Rogue Valley, Illinos Valley in southern Oregon, we have many micro-climates here. Right now it is hailing outside but local weather called for showers. We get twice the rain totals they report on the weather, it's just where we happen to live and the way the storms blow in.
They have temperatures on Accuweather also that may help if you have town names.
