2015年五月和春季圣克劳德天气摘要
2015年五月和春季圣克劳德天气摘要
Rain, rain, and more rain. That's what dominated May 2015. Going into May, St. Cloud had only 2.可测量的降水量为61英寸，比全年少3英寸多. However, May produced 6.03 inches of rain比平均水平高出3英寸多一点. 总降水量是1 - 4月的两倍多. 2015年5月也是圣路易斯市第12个最潮湿的五月. 云降水记录可以追溯到1894年. Both 2012 (8.76英寸，第二潮湿)和2014年(6.74英寸，第八潮湿)排名更高.
有7天至少有半英寸的降雨，有两天是连续的, May 16 and 17, with over 1.4 inches of rain. The 1.5月17日的降雨量为41英寸，打破了此前1英寸的日记录.10 inch, set in 1910. 然而，5月16日的总降雨量为1.48 inches. 那些天还产生了15次龙卷风 包括赖特县达尔文附近的一次着陆，损坏了一些谷仓.
The big rainfall allowed St. 云要快赶上年降水量. At the end of the month, St. 云的1 - 5月降水量已攀升至8.64 inches, 0.36 above average.
部分地区的降雨量甚至更大 位于明尼苏达州中部、中西部和西北部 这个月的降雨量为6-8英寸.
降雨模式是由于北美风向模式的重大变化造成的. 而不是持续的从西北到东南的气流模式，使天气相对干燥, 在俄勒冈州和加利福尼亚州，有时会有更多的风暴进入美国，还有一些北部风暴向南推进，穿过落基山脉，导致所有平原州都更加潮湿, producing the 德克萨斯州和俄克拉荷马州的洪水问题 the second half of the month.
到月底，所有的雨水都 大大改善了明尼苏达州大部分地区的河流流量 ，界水的一部分除外. The US Drought Monitor 在明尼苏达州北部三分之一的地区，以及从东部双城东南到红翼的地区，仍然保持中度干旱, still a large improvement over the previous 6 weeks. At this point, 是否存在地下水短缺(不受少雪季节的影响，因为融化的雪在地面融化之前就离开了)或地表水短缺，现在重新补给的溪流是值得怀疑的.
大雨带来的一个大问题是，适合完成农活的日子很少. The week ending May 24 only had 2.8 suitable days and the current week summary will be out later today.
持续的云层使五月的气温下降
5月整体多雨(14天可测雨量). 由于持续的云层覆盖，云确实控制了气温. 圣保罗的平均高温. Cloud was 66.3°F, 2.5°F cooler than average. 五月份的平均气温是55度.1°F, 1.4°F cooler than average. 有20天的最高气温低于70度. The first 80-degree high 该赛季的比赛被推迟到5月27日. 这是自1997年(5月31日)以来最晚的80度高温，也是有记录以来第11次在5月27日或之后出现80度高温. 这与3月上半月相对较早的60华氏度和70华氏度的高温形成了鲜明对比, 主要是由于缺乏积雪覆盖.

寒流也很明显在5月10日和11日以及5月16日至17日的风暴过后，最高气温在50度以下. 18日，红河谷地区飘起了雪花，伴有十几、二十几度的风寒，还下了一双St. Cloud frosts on May 19 and 20.
春天结束时有点温和和潮湿
5月31日也标志着气象春天的结束, 因为气象上的夏季被定义为一年中最热的三个月(6月1日至8月31日). 总体而言，今年春天的气温略高于平均水平.6°F, 1.比平均水平高出1华氏度)，而5月份非常潮湿，使三个月的降雨量达到8.05 inches, 0.98 inch above average. The only spring snowfall was 3.3 inches in March, and 1.0 inch in April. The 4.3 inches was 6.比3月至5月的平均值低7英寸，与过去两年的降雪形成了巨大的对比.
圣保罗从来没有下过霜. 6月1日以后会有云，所以现在应该对所有的植物都是安全的.
