When I lived in Laramie, Wyoming, I learned that April doesn't mean that spring has really arrived. Wednesday looks like a day like that, with the possibility of a significant snowfall as a powerful low pressure system forms in the lee of the Rockies. Let's predict the 24-hr accumulated precipitation amount (the liquid equivalent, not the depth of snow).
