Quickly on the heels of a storm that produced heavy snow and blizzard conditions along the Yukon Delta on the 2nd into the 3rd, another storm impacted the area on the 5th into the 6th.  A 986 mb low near the Pribilof Islands at 0600AKST on the 5th strengthened to 976 mb near Nunivak Island by 2200AKST on the 5th.  The low moved into the lower Kuskokwim Valley during the early morning hours of the 6th and began to slowly weaken.  The low produced heavy snowfall across much of the Yukon Delta.  Snow accumulations of around 8 inches were observed at Emmonak, Marshall, Mountain Village and Scammon Bay.  The snowfall was estimated due to strong winds. Snow drifts of 2 to 4 feet were observed at Mountain Village.  Blizzard conditions were observed from approximately noon AKST through 1600AKST on the 5th at Mountain Village.  The wind gusted as high as 42 kt (48 mph) at the Mountain Village AWSS and the visibility was reduced to one quarter mile or less in snow and blowing snow.  It is also likely that there were blizzard conditions at Marshall at times during the afternoon on the 5th; however, the visibility sensor on the AWSS was inoperable.  There was a peak wind gust of 42 kt (48 mph). A peak wind gust of 42kt (48 mph) was also observed at Saint Marys, however, the visibility as the Saint Marys AWOS only briefly dropped to one quarter of a mile.

An area of low pressure formed over Oklahoma during the day on the 8th and advanced northeast across Missouri.  There was strong support in the upper levels of the atmosphere as a negatively tilted shortwave lifted northeast out of the southwest US.  A large deformation zone formed to the northwest of the low pressure.  Snow began to fall over southwest Iowa by evening and spread into the central counties by mid to late evening.  Snowfall amounts of 2 to 4 inches were common.  Concentrated areas of heavier snow occurred in and along the center of the deformation zone, with a band of heavy snow extending from near the Lamoni area of south central Iowa, northeast to Winterset.  In Winterset for example, 6.5 inches was reported by shortly before 0300 CST.  Numerous power outages were reported in the area due to the heavy wet snow.  The snow was heavy enough in Union County to topple high tension power lines.  Temperatures were near freezing at the time the wet snow fell, causing it to cake on trees, which still had part of their leaves remaining.  Power outages occurred in many areas, even with only 3 to 4 inches of snow due to tree damage.  Damage was fairly extensive in portions of the metro Des Moines area, as was the case in most cities.  At one point, nearly 10,000 customers were without power in portions of the Des Moines metro area, with over 500 still without power 24 hours later.  Several hundred customers per county remained without power southwest through Madison, Union and Ringgold Counties as well.
