Precipitation in water equivalent not inches of snow (at 20,000 feet (6060 meters) 0 to 0.50 inches (12.5 mm). 15% chance of getting up to 0.50 inches (12.5 mm). Also 70% chance of getting less than 0.10 inches (2.5 mm) . Not sure why some models are showing up to .50 inches (12.5 mm) given northwest flow.
A basic conversion is 0.10 inches (12.5 mm) in water equivalent is equal to about 1 inch of snow<
Summit Clouds: Not many perhaps just a few early.
