After a dry opening to July, shower activity picked up over Upper Michigan the last several days. The south-central U.P. locations of Norway, Bark River and Powers began the week with over two inches of rain. Yesterday, it was the northwestern U.P. that saw the most. Twin Lakes in Houghton County received 1.05 inches, while Jacobsville had 0.99. To the south, significant rain fell along the Wisconsin line from Gogebic into Iron Counties. Watersmeet received 0.73 inches, while our Peavey Falls observer reported 0.87. To the east, amounts tailed off. Iron Mountain had 0.16 inches with only 0.11 inches at Norway.
For the month, Peavey Falls already has accumulated 1.57 inches. As an illustration of the spotty nature of summer rainfall, the National Weather Service (NWS) near Negaunee reports less than half that amount (0.75). Farther east, it finally rained for the first time this month starting last night at Sault Ste. Marie. As of late morning, the total for the month there was less than a quarter-inch.
We are still running a surplus of precipitation for the year. The NWS is at 21.40 inches for the year. The average is 17.29 inches. Each of the last seven months has an excess of precipitation compared to average. The long-term drought index shows the western half of the U.P. in a ??very moist?? state (Image 1 above). I would question that designation and I??m sure those U.P. residents on inland lakes with continuing low levels would do the same. However, the overall moisture situation is looking much better than the last several years.
