Another Summer-Fall Rain Shortfall
Sixth 干旱July-September
2013年9月 Saint Cloud 天气 Summary
September had a major rain event in mid-month, but continued the dry conditions 从七月初开始. 九月的雨量. 云是1.87英寸,1.59 英寸es short of the September average. 的 rain shortfall spans the months of July, August, and September. During that three-month period, St. 云只有4个.15英寸 sixth lowest total for July through September. 总的来说, St. 云是6.还差41英寸 从七月初开始. Last year's June-October shortfall was worse (9.比平均水平低08英寸), but the past three months ranks as the second worst in this series of dry spells during the growing season, which has involved 5 of the past 6 years.
的 result of the rain shortage is statewide topsoil that ranks as being short of moisture over 60% of Minnesota. About two-thirds of the sub-surface moisture is ranked as being short. 的 low water supply has led the upper portion of the Mississippi River to rank among the 10 percent of lowest stream height, 根据双方 USGS Minnesota River Gauge Network 和 明尼苏达州DNR地图. 的 worst conditions are from Brainerd and Aitkin upstream past Leech Lake and Grand Rapids.
的水位 Mississippi River level below the University Bridge dam 只有4.4英尺. 的 three lowest river stages at that dam begin at 3.76英尺. 的 Sauk River at Rivers Edge Park in Waite Park 只有1.6英尺. 最低记录是0.1936年的05英尺.
然而, the first major rainfall since the heavy rains ended in June developed on 9月14日. 1.23英寸es that fell on that day was more than a quarter of the precipitation over the past 3 months. 此外,还有5个ome major September rainfall in west central Minnesota and along the Canadian border. 的 rain to our north eased the drought conditions defined in the 美国干旱监测 to the north of Little Falls, Milke Lacs Lake and Detroit Lakes.
的 rest of the southern two-thirds of Minnesota and a good chunk of northwestern Minnesota still have drought conditions. 的 conditions are worse across central Minnesota from Willmar and Litchfield through nearly all of Stearns County, 安嫩代尔, 克利尔沃特, Clear Lake and to Foley and Milaca. 的 最大雨量不足 are now along the Iowa border and especially in southeastern Minnesota in counties bordering the Mississippi. 的se areas are as much as 7-10 英寸es short of rain since the last week of June.
Temperature-wise, September was a roller coaster month with cooler than average weather during the first week of the month, and during September 13-21 (first 30-degree low since May; 6 days with highs in the 60's). 然而, this was balanced by a hot period in early September (2 90-degree highs, 4 lows of at least 60) and more warmth over the last 10 days of the month. 总的来说, 2013年9月 ranks as tied for the 17th warmest September on record (62.9°F). While there have been 4 warmer Septembers in the past 15 years, 2009 (63.3°F), 2005 (63.2°F), 2004 (64.1°F), 1998 (62.9°F), the other 14 warmer Septembers were earlier than 1948. 创纪录的高温 were set twice on September 28 (record warm low of 65, record warm average of 73).
的 first few days of October will continue the warmer than average weather that finished September. 然而, a major West Coast storm has the potential to produce widespread significant rain during Thursday through Saturday. This storm will push into the southwestern US by mid-week, then push northeastward rapidly by Friday. That will really pull a lot of Gulf of Mexico moisture into this storm, so there will be the potential for another half 英寸, 英寸, or even more rainfall over at least parts of Minnesota during the end of the week. It's still a bit early in the week to be sure about the late week, but it will have the potential of widespread rain.
