August looks to be a warmer than average month in the Great Lakes Region. Above is the latest 8-14 day temperature outlook from the Climate Prediction Center. We’ll stay near average early next week (average high is 83), then we’ll be above average during the middle – latter part of next week.
Much of the Central U.S. and Great Lakes is expected to have below average rainfall. Rainfall is likely to continue to be above average in the Desert SW and much of Alaska. Mostly afternoon and evening showers and thunderstorms have caused isolated flash flooding in the Southwest. Beneficial runoff has increased the flow of the Colorado River, though river levels are still below average.
This weekend will be mostly sunny and dry. With light winds, Lake Michigan should be reasonably calm and green flags will be out at the beaches for safe swimming.
