A moderate area of low pressure was positioned over the central and southern Great Basin and central Rockies. A strong storm moved north-northeast from the Great Basin to "close off" over western North Dakota by November 1st. This low deepened and slightly retrograded and wrap-around precipitation occurred over far southeastern Montana. A lack of a cold air source proved to be a factor as the precipitation began as rain over southeast Montana the night of October 31st and continued as rain the morning of November 1st. A change over to rain occured later November 1st...as cold air moved into the area. Snow and increasing wind resulted in blizzard conditions over southeast Montana. The snow eventually ended the night of November 1st.
