Precipitation tapered off for the West Coast, but heavy snow persisted across the Northern and Central Rockies on Saturday.

A strong low pressure system moved off the Rocky Mountains and into the Northern Plains on Saturday. The system continued pushing a cold front through the Rockies, which allowed for more heavy snow to develop from Montana and Wyoming, into northern Colorado. Most areas of Montana saw another 2 to 5 inches of snow on Saturday, while parts of Colorado saw just over a foot of snow at highest elevations.

Snowfall rates at highest mountain peaks in Colorado were estimated at 1 to 3 inches per hour early Saturday morning. The northern side of the front advanced eastward into the Northern Plains and brought heavy snow with it. North Dakota saw snowfall totals from 6 to 10 inches, with up to 20 inches possible in some areas. Strong winds persisted along the cold front with gusts from 30 to 40 mph.

This created blowing snow and poor visibility, thus, the Northern Plains as well as the Northern and Central Rockies saw dangerous driving conditions. At the same time, a warm front stretched eastward from this system and moved over the Upper Midwest and into the Great Lakes.

Rain showers moved from Wisconsin and into Michigan and the Upper Peninsula of Michigan as temperatures remained above freezing. However, northern Minnesota saw snow showers turn to freezing rain and rain showers during the day as highs warmed from the 20s overnight to just above freezing by midday.

In the West, a few more rain and high elevation snow showers continued from the Intermountain West through the Great Basin and central California. The West remained cool as arctic air continued to pour in from the Gulf of Alaska.

ON THIS DATE....... Edmund Fitzgerald, considered to be the most famous ship sunk in the Great Lakes, was swallowed by Lake Superior on this date in 1975 during a horrific storm. Twenty-nine lives were claimed by the lake that day. Twenty-three years later, another storm took a similar path as the one that claimed the Edmund Fitzgerald and created waves 20 feet high on Lake Michigan.
