在冬天的第一个半月里, 北半球最冷的冷空气被锁在格陵兰岛, Siberia, and the Arctic Ocean, 只是偶尔会到达哈德逊湾. However, 把冷空气留在一个没有阳光的地方多一个月，冷空气就会变得更冷. 因此，如果这些空气被推向中纬度地区，影响可能会更大.
During the second half of January, 北极气流被推进到加拿大中南部和东南部, the Northern Plains, Great Lakes, Mid-Atlantic and Northeast. 1月最后15天的平均气温为零下2度.8 degrees (avg. high 6.7 degrees; low -12.4 degrees), which would rank as the 6th coldest January in St. 云记录，如果它保持整个月. This included St. 自2009年1月16日以来，首次出现两次零下30度或更低的云层, 1月30日的最低气温为零下34度，是10年来最冷的气温, 气温连续三天低于零度, the 7th coldest high temperature in St. Cloud records (-17 on January 30), and 连续15天气温低于零度或更低.
有三股来自加拿大中北部的北极气流. 第二次高峰在1月27日，在Kabetoagama地区出现了零下49度的低温, Minnesota and -21 in St. 云与几个地区站低于零下30度. 安大略省西北部部分地区的气温低至零下51度. 在1月31日第三次飙升的高峰期，棉花进入市场 northeastern Minnesota 卡贝托伽马的最低温度是零下53度，而温度是零下50度. 离我们更近的地方，布雷纳德的最低气温为零下43度，而长草原和小瀑布则达到零下36度. At the St. 云区机场最低气温为-34℃，如上所述.
29日和30日，第3次寒潮袭来，同时刮起了强风. 明尼苏达州中部亚历山德里亚最冷的风寒为零下63度，圣路易斯市的风寒低至零下59度. Cloud.
One person died in Rochester, 由于上周日夜间的暴晒，在爱荷华大学校园里发生了一起寒冷天气死亡事件.
这次感冒爆发被描述为一代人中最冷的一次，但这有点言过其实. 连续16天零度或更低的最低气温(包括2月1日), ties for the 15th longest in St. Cloud records. 然而，1996年有连续20天的最低气温为零或更低. 记录是1936年从1月17日到2月22日连续37天. 1899年1月28日至2月4日，气温全天保持在零度或零度以下的最长记录是8天. 1996年的感冒爆发造成了连续5天如此寒冷的天气. There have now been 5 days with a low of -20 or colder几乎是整个季节的平均水平.
然而，整个一月份的平均气温是8度.0 degrees, 3.6 degrees colder than average. Why relatively mild? 在1月的前16天，平均气温为19.5 degrees (high 28.9 degrees, low 10.1 degrees), 11.6 degrees above average. That would have ranked as the 10th mildest January on record if it had held up. 12月和1月的平均值仍然是1.比平均温度高1度，因为这两个月的前四分之三都很温和.
1月大部分时间都没有雪，但也有6个月.这个月最后11天的降雪量是1英寸. The most was 4.1 inches from January 26 through 28. 这些额外的雪在第三次北极涌流中被吹得相当大, 是什么导致了漂流和结冰. St. 云错过了这个月最大的降雪， narrow band of heavy snow 2019年1月18日，明尼苏达州东南部部分地区降雪量达到10-12英寸.
For the season, St. Cloud has only 21.2 inches of snow, 6.3 inches below average. Of course, 从去年冬天以及2012-2013年和2013-2014年的冬天我们知道，2月到4月期间我们会下很多雪.
The total moisture in the snow was 0.41 inch, 0.24 inch below average.
1996年1月底至2月初的寒流仍然是近年来最冷的时期. Cloud records. Numbers in blue are daily temperature records. 2月2日的零下20度，追平了美国历史上最冷的温度. Cloud. 2月2日的零下40度是上一次气温降至零下40度. 气温连续6天低于零下30度甚至更低创下了纪录. 连续20天的最低气温为零度或更低(第四多，也是1979年以来最多的). 1996年2月2日，塔还以零下60华氏度创下了明尼苏达州的低温记录.
