For the third straight year, St. Cloud had a major dry period during the summer. While much of August intensified the dry conditions, two major rainfall events on the 3rd and the 25th eased the conditions considerably.

的 total August rainfall at St. 云区域机场为4.18英寸，0.比正常高25英寸. However, all of the rain only fell on 5 days, the fewest number of days in August 与 measurable rainfall 自1996年以来. St. Cloud had nearly its own private rainstorm on 8月3日 as the Airport received 2.36 inches, the most daily rainfall in St. Cloud since October 4, 2005 when 3.42 inches fell (nearly the same amount of rain, 2.35 inches, fell on August 24, 2006). 的 second rainfall of August 27 produced 1.42英寸在St. 云机场和倾倒 2-3 1/2 inches of rain along the I-35 corridor from Grand Marais and Duluth into the Twin Cities Metropolitan Area.

在第二次降雨之前，圣. Cloud's rainfall shortage between June 15 and August 25 was 3.76英寸(5英寸.14 actual; 8.90正常). 的 August 29 growing season rainfall from the Minnesota State Climatology Office showed a rain shortfall of 5-7 inches from Wright and southern Benton Counties through the Twin Cities Metropolitan Area. 的 rain shortfall caused parts of Minnesota to be ranked in moderate drought conditions by the National Drought Mitigation Center's 干旱监测. Before the August 25 rainfall, 河流, as shown by the Minnesota DNR Waters 河流 map, was in the lowest 10% of years along the Upper Mississippi River, the Upper St. Croix, and along the Mississippi and its tributaries from St. 云层穿过双子城. Despite the late month rainfall, the mid-summer rainfall deficit still stood at 3.09英寸和 河流 was still only in the lowest 25% of years from St. Cloud to the Twin Cities 与 continued very low 河流 to our north and east.

During the entire meteorological summer (June 1-August 31), Saint Cloud had 9.95英寸的降雨量，1.83 inches short of the normal summer rainfall.

Because of the rainy spring, crops have progressed fairly well in Minnesota, according to the 明尼苏达州农业周刊 来自美国农业部. 事实上, the warm dry weather towards the end of the month helped wheat and oat harvests to return to near normal. Still, about 50% of the Minnesota topsoil was listed as being short or very short of moisture.

圣. 云区确实错过了一次 heavy Red River Valley rain event that produced up to 3-4 1/2 inches in west central Minnesota. That Upper Red River Valley is one of the few areas 与 above normal rainfall on the growing season rainfall map in the August 29 growing season rainfall 报告.

Still, the summer dry spell does not even approach the six and a half inch rainfall shortage 到2007年的这个时候 four and three-quarters inch shortfall in 2006.

正常的ly, 的 温度 Aren't Quite As 正常的

August was the only month of the 2008 summer that was significantly warmer than normal. 的 Saint Cloud Regional Airport averaged 68.8月份是4华氏度，也就是1.比正常高2°F. 的 warmer weather produced 20 days 与 a high of at least 80°F, pushing the average temperature a bit above normal. However, only August 17 had a high cracking 90-degrees. 的 summer of 2008 had only three days 与 a high of at least 90, the fewest number of 90度高点 自1993年以来.

的 remarkable part of this summer in St. Cloud was how normal the temperatures were. 六月和七月加起来, there were only 4 days 与 an average temperature more than 6 degrees away from normal. 2008年8月，圣. Cloud more than doubled that total (7 days), thanks to six straight days of above normal temperatures 17号到22号之间. Still, only 11 of the 92 days had an average temperature more than 6 degrees from normal.

While late August into early September had some of the warmest temperatures seen all summer, the weather pattern changed quickly after the Labor Day Weekend. 的 steering winds in western North America pushed back into the US after spending much of the previous month along or even north of the Canadian border. 这就建立了圣. Cloud area for cooler than normal temperatures for most of the first week of September. Beyond that, there are no strong trends.
