A strong low pressure center will produce significant snow for the first half of the holiday weekend. Travel headaches are ahead for early Christmas holiday travelers. The large storm will be far reaching, as every state in the west will likely be affected by the storm. Watches, warnings, and advisories extend from the West Coast into the High Plains.
The first wave of energy will move through the region today, bringing a round of snow into the region. Snow will gradually increase and heavy rain will move through the Southwest. Flood Watches continue for the desert areas in California and Arizona. Flooding is possible with some storms today as an inch of rain could fall in some areas.
As the main wave of energy moves across the west Friday, snowfall will increase. The Cascades and Sierra will see the snow first, expanding in coverage throughout the day. Rain will move through California.
On Saturday, snow will push through the rest of the western mountains. The Wasatch, Tetons, Bitterroots and Rockies will see snowfall increase throughout the day.
Well over a foot of snow will fall in the Cascades into the Salmon-Challis range. The Sierra could see nearly 3 feet of snow in the highest elevations.
A yardstick might be necessary to measure snow accumulations in the Wasatch. Up to 3 feet is possible, with around a foot into the Rockies and Tetons.
