Merger of Two Storms Will Spark Heavy Rain and Snow Across Rockies and Plains

Two separate storm systems are forecast to merge over Christmas weekend as they meet up over the Rockies and the Plains states.

This merger will trigger a number of major weather impacts heading into the busiest stretch of the holiday weekend. Here is what you need to know about this potentially disruptive forecast.

The first storm is currently dumping significant amounts of rainfall in Southern California and the Desert Southwest. The second system is setting up over the Pacific Northwest with the threat of rain and snow.
