Preliminary Snowfall Totals January 23 - 25 2010

Another somewhat unusual winter storm has brought blizzard conditions to portions of the northern plains, after a wild weekend of rain, snow and sleet. There was upwards of 10 inches of snow in the far northern sections of North Dakota and parts of northwest Minnesota. Below is an image representing the preliminary snowfall totals. Remember, these are based on 3 days worth of information from Friday morning, January 22nd through Monday this morning, January 25.

Snowfall totals were greatly reduced due to the periods of rain, sleet and freezing rain falling for a prolonged period early in the storm.  Rain and freezing rain began early on Friday in western North Dakota, and spread eastward into the Red River Valley and west-central Minnesota by Friday evening.  Freezing rain changed to sleet and then snow through the overnight hours, producing ice and slush accumulations ranging from one half inch to and inch or more in the Red River Valley, with snow accumulations pushing 6 to 8 inches across the Devils Lake Basin.  Saturday morning saw additonal 3 to 6 inch snow accumulations  across northeast North Dakota and much of northwest Minnesota.  Strong gusting winds and additional 2 to 4 inch snow amounts Sunday night into Monday produced blizzard conditions across central and eastern North Dakota, into western Minnesota, and portions of eastern South Dakota.  

Total snowfall for the weekend was generally less than forecast.  However, the combination of rain, sleet and snow resulted in a total liquid equivalent precipitation generally between an inch and an inch and a half... which was quite close to what was originally expected. 

The above graphic is based on preliminary information from NWS Cooperative Weather Observers, as well as other state and local weather reporters. The information is designed to show where the more significant snows accumulated, and does not account for the significant variations that can occur in a snow storm.

As the low departs the region to the east, winds have gusted to over 50 mph in many locations. Below are some of the peak wind speeds across the region for Monday January 25th. These are peak wind speeds in miles per hour since midnight. The time of the peak wind speeds below represent the first occurrence.
