How Rainy Has It Been So Far This Summer?

Radar estimated rainfall departure from normal between May 22 and August 20, 2010

As you can see from the above graphic, the rainfall this summer has been well above normal across most of the area - especially across northwest Wisconsin. In fact, some places in far southeast Sawyer County, to the southeast of Winter, have seen nearly 16 inches more rain than they would normally expect in this same timeframe. The one exception to the "rainy summer" would be from the Range cities northeast to the Gunflint Trail in Cook County, where drought conditions were still holding on.

Below are rainfall totals for the same time frame as the image above (May 22 - Aug 20), and departures from normal, for both the Duluth and International Falls climate sites, as well as a few co-operative observer locations. Note that the co-operative observer data is not yet official.
