A strong low pressure system affected western and central North Dakota October 11th and 12th last year. This system was a "Colorado Low" since the low pressure developed in Colorado before moving into northeast North Dakota on the evening of the 12th. Above freezing temperatures existed in the lower levels of the atmosphere across central North Dakota with this storm. Enough instability within the warm air existsed across the James River Valley to cause thunderstorms with pea size hail to occur in southern Stutsman county on the 11th. Therefore, predominatly, rain was seen along and east of Highway 83 with this storm, with a trace of snow in Minot. Accumulating snowfall was seen along and west of a line from extreme western Sioux through extreme western Renville counties where sub freezing air from Canada was drawn into the western side of the low. The snowfall totals for the event are shown below both within a table and a snowfall map. The highest snowfall total received by the National Weather Service was 11 inches in Beach.
