Mid-Summer Dry Period Won't Show in Summer Records 的 8月26日有强降雨 drowned out the dry conditions we've had for most of the summer. During the period of 6月 15 through 8月 25, rainfall in 圣人云 was four inches below normal. 雨量不足, which was concentrated from Willmar through 圣人云 east and southeastward to Pine City and the northern and western suburbs of the Twin Cities Metropolitan area, 最能看出的是 8月22日生长期雨量图 from the Minnesota State Climatology Office shows rainfall 20%-30% below normal from 圣人云 south and east to the northern and western suburbs of the Twin Cities. 暴风雨过后(八月二十九日雨量图), only much of Sherburne County and northeastern Wright County have seasonal rainfall 10-20% below normal. 的 rest of the dry conditions are limited to the Saint Croix Valley and northeastern Minnesota. Without the first two weeks in 6月 and the big 8月 27 rainfall, 九周的总数, 整个夏天都能保持, 会被列为 圣克劳德历史上第二个最干旱的夏天. 相反，整个夏天以1美元结束.比正常低62英寸. 的 actual effect of the dry spell was worse than the numbers show due to both the intense heat (increasing water usage) and getting a lot of rain on a few days (more rain runs off into rivers and lakes, 但进入土壤的较少). 请注意 8月23日干旱监测 from the National Drought Mitigation Center shows only that a few areas in extreme eastern Minnesota and the Duluth-Two Harbors area are part of the moderate drought conditions that dominate Wisconsin, 上密歇根州, 和爱荷华州东部. 的 last significant dry spell that was similar to this year was a 10-month dry period from 7月 15, 2003 through the rest of the 2003 growing season and continuing through mid-可以 2004 after the ground thawed. 的 rainfall deficit from mid-summer 2003 through 4月 2004 in 圣人云 reached more than six and three-quarters inches until the rains came. Although this 10-month dry period could not compare to Minnesota's last major drought during 1986-1989, the period was intense enough to cause much of the state to be classified in the moderate to severe drought categories
