2023年1月. 云天气摘要

到1月为止的第五个雪季

的 end of January is a little past halfway through the St. 云，明尼苏达州，雪季(通常十一月至三月 有时从10月到4月). 在这一点上，圣. 博彩平台大全，官方St. 云降雪点，已收到46个.3英寸的雪，20.比平均水平高出3英寸. 的 average for an entire snow season is only 1.高6英寸，是47.9英寸. 的 snowfall total through the January ranks as the 5日雪 雪季的前5个月. 云记录和1996-1997年以来的降雪量. 记录是54.2英寸，时间设定在1936-1937年. Elsewhere in Minnesota, there has been generally more than 3 feet of snow in the eastern two-thirds of Minnesota (设置 to season snowfall) with over 4 feet (red) in much of east central and northeastern Minnesota. Duluth has seen more than 80英寸 of snow so far this season.

2023年1月占了18个.6英寸厚的雪. 这一总数是美国的两倍多 8.平均8英寸 排名为 这是有记录以来的第10次降雪. ,其中包括 13.1月3-5日的降雪达8英寸, 圣路易斯市第13大降雪. 云记录，排名甚至高于 1991年臭名昭著的万圣节暴风雪 (13.3英寸宽. 云). 的 1月3日-5 storm is the second top 20 single storm snowfall of this season (December 13-18 was the other one). 它打破了每日的记录 1月4日降雪(7.0英寸). 1月3日 and 4 each had more than 5 inches of snow, bringing the 季节总计5英寸天 to 3. 的re had been only 2 days with at least 5 inches of snow in the past three seasons combined.

的re is more than a foot of snow on the ground (medium blue on the 明尼苏达州雪深图 from the Department of Natural Resources) with a foot and a half (purple) in the eastern half of north central and northeastern Minnesota

从11月到1月第三个最潮湿的月份

的 amount of liquid precipitation between November and January at the St. 云机场已经5年了.61英寸，两倍多 三个月平均值为2.92英寸. 这是 3rd highest November through January precipitation total in St. 云记录. 1月份的降水量为1.60英寸，只有0.还差12英寸 10个最潮湿的一月. 12月各月降水总量(1.90 inch) and January have nearly equaled the average 3-month precipitation for the entire winter (Dec 1-Feb 28), 2.32英寸. 现在是3.从12月1日到现在已经有50英寸了 10th place among the wettest meteorological winters 我们还有一个月的时间.

上次这么早就下雨了.....

1996-1997年再次保持着 11 - 1月降水量与6.54英寸. 所有的雪和湿气都进来了 1996-1997, with more than 100英寸 of snow in west central and northwest Minnesota for the entire season, 最终以 大福克斯最严重的红河洪水 （城市被水淹了一个月） second worst Red River flooding in Fargo-Morehead. 的 明尼苏达河 在那个季节也产生了严重的洪水. We don't have 100英寸 of snowfall yet in that area. 和, the camel that broke the straw back was an April 4-6 blizzard, which fell just as the frozen rivers were thawing. That snow, once it melted, pushed the flooding to record levels.

然而，1964-1965年，降雪量最大 寒冷的季节，所有在圣. 云(87.9英寸)，不出现在 到一月份前10个最大雪的季节. 这是因为近69英寸的降雨量 从二月到四月，包括51.1966年3月7英寸 圣. 云记录. 的 2012 - 2013赛季 (第四次降雪季节 与78年.5 inches) also had a major late season contribution with over 57 inches in the last 3 months. 另一个 近期降雪季节前5名, 2013-2014 (75.5英寸)，排名 10月10日- 1月降雪.

Steady Parade of Wet Storms That Stall Out Producing Heavy 降水

It requires a lot of moisture to be able to produce such high snowfall totals. 的 overall weather pattern in January produced a continued sequence of landfalling Pacific storms, some of which moved northeastward through the Plains. That allowed some Gulf moisture to creep into these systems. 的 extra step in these top 20 snowfalls was that the storms tended to intensify, 然后在威斯康辛州或爱荷华州附近停下来, 长时间降水的产生长时间降水的. It takes that extra time to be able to produce widespread snowfall of a foot or more in Minnesota.

温度 Were Running Near 记录 Warm Levels First Three Weeks

后不久 1月3-5日的风暴, the Pacific storm track split into two branches, one tracking from the Rockies through the Central Plains and Northeast or Mid-Atlantic, and the other well to the north in central Canada. This kept the really cold air trapped in Greenland for much of the month, allowing Minnesota to be at a near record mild pace through the first three weeks of January. 然而, the pattern changed to a northwest-to-southeast flow pattern during the last 8天 of the month. This allowed arctic air to move back into the central part of the Canadian Arctic Coast, 然后向东南移动进入平原. 那次降温不像那次那么冷 圣诞节前北极爆发，但停止了 低温条纹 nearly as mild as the average highs seen earlier in the month, and eventually produced 6天 with a 零度或更低, including three straight days in the minus teens. 的 last two days of the month had lows of -18, the coldest of the season so far. 所以，整个月的结果是17.平均2度，5.4 degrees above average, but merely the 22nd warmest January in St. 云记录.

一月温和的第一部分 4 record warm temperatures and a tie for the 5th. 的 low never dropped below 30 degrees on 1月15日-17, 创造了两项记录，并列第三项, and the average temperature on 1月15日 and 16 was 34 degrees, breaking the record warm averages for those dates.

总结到目前为止的寒冷季节

在雪季快过半的时候, the statistics show that snowier than average and wetter than average in much of Minnesota. 温度-wise, there have been enough major arctic outbreaks to produce nearly a season's worth of 零度或更低的温度 (4). 然而，计数 零度以下的低点包括1月31日在内，现在是21天. That's less than halfway to the seasonal average of 42.7天. 和, the November through January average temperature is 1.比平均温度低4度. 下表总结了更多

If you're looking for a prediction for the rest of the winter, note that the official 国家气象局 forecast was that the Northern Plains would be colder than average with no trend in precipitation. 也, there was unlikely to be enough precipitation to ease the major pre-winter drought conditions from the Mississippi River westward. 然而,, there has been major relief in the Dakotas into Minnesota and in parts of the southern Rockies, 包括内华达和加州. (设置 美国干旱监测的两周比较 to the latest versus November 22, the time of the forecast). 所以，我不会参加那个比赛.

在明尼苏达州, the improved water conditions will help river and lake levels substantially when the snow melts. 然而, ground water recharge will require spring rainfall after the ground thaws.
