In the spring, the snow gets warm and wet in the afternoon and then freezes over night. To get the best snow conditions, it's a good idea to start on Heavenly's Nevada side and work your way over to the California side. This is because the sun hits the Nevada side first and softens up the hard snow. When the snow on the Nevada side starts to get too warm and mash potato like (around 10:30 or so depending on the day), you can keep moving west and play on the California side, which will just be getting hit by direct sunlight. If you time it right, you should be able to have snow that is in the spring sweet spot between icy and mushy.
