Major Hailstorm In Bayfield and Ashland Counties
The significant supercell that later went on to produce a tornado in the Morse area originally was a significant hail producing storm. The first hail report in the area was received at 5:20 PM from 2 miles southeast of Iron River of quarter size hail (1.00" in diameter). More hail reports were then received between the Iron River and Mason/Grand View areas that reached up to 2.75" in diameter. Some trees were snapped off including red pines and oaks. A police car had its windshield cracked, and three other vehicles were dented, as large amounts of wind-driven golfball sized hail fell in that particular location. There were also reports of wheat and corn fields being destroyed, shingle and siding damage to some houses, and that the Highway Department had to scrape the roads clear of several inches of wet leaves that were stripped off by the hail.
Below is an image from the National Severe Storms Laboratory that basically provides an estimate for the maximum size of the hail in a given area, and integrated over several hours on the afternoon and evening of July 27th. The result is a "hail swath map". You can see that the NSSL algorithm estimated a broad swath of at least golfball sized hail, with some pockets of hail up to 3 to 4 inches in diameter. We didn't have anything quite that large reported to us.
