2-3 different storm systems remain possible next week across the Intermountain West. The first storm system will likely lose strength and snow potential as it battles the massive high pressure ridge currently anchored over the West. This will create wild fluctuations in snow forecasts through this weekend.
You can see the storm track (yellow), high pressure ridge, and storm systems lined-up in the infrared satellite image.
The first storm system essentially sacrifices itself to grease the atmospheric skids for the 2nd and potential 3rd storm systems.
How likely is the 3rd storm system? The data is split. The 2nd storm system could absorb the 3rd and become a single larger storm system. Time will tell.
