Where we stand now:

Future prospects:

  • The August precipitation outlook offers equal chances of below-normal, near-normal, or above-normal conditions in most Minnesota counties. However, the August outlook leans towards above-normal rainfall in far southwest Minnesota. August precipitation normals range from under three inches in northwest and west central Minnesota to over four and one half inches in southeastern counties.

  • The August temperature outlook favors below-normal conditions across the southern one-third of Minnesota, and equal chances of below-normal, near-normal, or above-normal conditions elsewhere. Normal August high temperatures are around 80 degrees to start the month, dropping to the mid-70s by month's end. Normal lows are around 60 degrees early in the month, falling to the mid-50s by late August.

  • The 90-day precipitation outlook for August through October indicates equal chances of below-normal, near-normal, or above-normal conditions across Minnesota. The August through October temperature projection also offers equal probabilities of below-normal, near-normal, or above-normal conditions statewide.

  • The National Weather Service produces long-range probabilistic river stage and discharge outlooks for the Red River, Minnesota River, and Mississippi River basins. These products address both high flow and low flow probabilities.

From the author:

  • For most Minnesota locales, the summertime weather has been close to ideal. The state has not suffered a major heat wave or consistently unbearable humidity levels. With the exception of some northeast Minnesota communities, growing season rainfall totals have been adequate to abundant. And while some severe weather has been reported, the damage has been geographically isolated. The excellent growing season-to-date weather conditions are apparent when reviewing the latest USDA survey of Minnesota's two major commodities, corn and soybeans. In an early-August report, corn condition was rated 87 percent good to excellent. Soybean condition was rated 81 percent good to excellent.
