2021年2月和冬季2020-2021年圣克劳德，MN，天气摘要
注:本文为冬季气象摘要, 指一年中最冷的三个月(12月1日至2月28日). Astronomical winter ends on the spring equinox, which will be on March 20 this year. 在那一天，我们又回到了12小时的白昼. Also, 请注意，冷季可以用来指明尼苏达州一年中下雪的那部分时间(通常是10月至4月), 但可以更长)或供暖季节(7月1日至6月30日). 不，土拨鼠在明尼苏达州没用.

在经历了极其温和的十二月(6.0 degrees above average) and January (8.0 degrees above average), 在2月的前三周，北极空气涌入了落基山脉以东的美国大部分地区. 那次爆发的后果对我们的南方很严重, 德克萨斯州出现了创纪录的低温和两场大暴风雪, Arkansas, Oklahoma, and Tennessee, producing major accidents, power loss, 死于交通事故和体温过低.
However, for the Northern Plains, 这将是典型的北极爆发, 只有寒冷的长度接近记录长度. 气温连续5天保持在零度以下, the longest streak since 1996, 而且是在史上最长的17连胜记录之内. 气温在零度或零度以下的8天几乎是季节平均值的两倍. 连续13个早晨的最低气温为零度或更低, 这是自1月3日至15日以来的最长纪录, 1999, 也是史上最长的45连胜之一. 包括2月14日的零下28度在内，零下20度及以下的最低气温有5次. 然而，没有破纪录的低温. St. Cloud did manage to break a couple of record cold highs (12号-6,13号-5)但那是因为 old records were relatively mild (-5 on the 12th, -2 on the 13th).

Through February 20, the St. 云二月气温低于-1度，这将排在附近 2nd coldest February on record. However, 在北美的主要北极气源被拉入美国并变暖之后, 再也找不到北极的空气了. 气温急剧下降，使2月份的平均气温降至7摄氏度.6度，是有记录以来第19个最冷的二月. 寒冷被前两个月抵消了, 所以冬季气象平均温度是8.4 degrees, 1.4 degrees milder than the average. The Twin Cities also had a 低温:温度在零度以下的长时间 (St. Cloud doesn't have hourly records, 因为在20世纪80年代自动化之前没有每小时的温度测量).
During the arctic cold, 主要的风暴路径仍然在我们的南部，从落基山脉中部到墨西哥湾沿岸或南部平原, then to the Mid-Atlantic States. 这使得两场冰雪风暴袭击了美国中南部, 但却把大部分的雪挡在了明尼苏达州之外, until the last day of the month, when a poorly forecast snow band dumped 4.4 inches on St. Cloud and 6-9 inches just to the south of St. Cloud. That was the largest St. 云降雪自初季降雪起 October 20 (7.0 inches) and November 10 (7.2 inches). 那场雪使月死亡人数达到8人.4英寸，季节性降雪将持续到2月28日至37日.1 inches. There were an additional 2.3月1日早些时候，另一场暴风雪将达到2英寸，将季节性降雪量推至39英寸.3 inches. 到2月底的平均气温是34度.2 inches.
在我们这个地方，真正考验冬天长短的是我们盯着雪看多久. St. 从12月24日开始，地面开始出现至少一英寸厚的积雪，并一直持续到3月3日. 这是连续71天，地面上至少有一英寸的积雪. The St. 平均云量为连续86天. 我们不太可能达到平均水平, 因为三月的前十天天气温和.
