1999: Windstorm knocked down millions of trees in the BWCA, 19 people were injured.
1977: An intense squall line, or derecho, brought 115 mph winds to northern Wisconsin as the storms traveled from Minnesota to Lake Erie. A tremendous amount of forest was destroyed during the blowdown
1962: Downpour at Jackson, where 7.5 inches of rain fell in two hours.
Better Than Average
At the rate this year is going I half expected to see a freak 4th of July blizzard or Tropical Storm Bubba chugging up the Mississippi, maybe a small sharknado on Lake Minnetonka.
Instead we'll enjoy lukewarm sun with highs near 80F and a very comfortable dew point in the 50s. Not bad for the biggest holiday of summer.
A surge of warmer air may ignite a few T-storms tonight; timing is a bit tricky, but the risk of thunder increases by morning with a few scattered storms Saturday, with creeping humidity levels and enough murky sun for low 80s.
If the sun stays out most of Sunday the mercury may hit 90F for the first time this year. According to Greg Spoden at the MN Climate Office only 4 other years since 1974 have been "90-less" as of July 2. Spoden adds that 3 years - most recently 1993 (another very wet summer) - experienced NO 90s at all in the Twin Cities. More details below.
We cool off again next week before heating back up the following weekend. No sustained heat or humidity is on tap and I suspect the worst of monsoon season is behind us now.
Meanwhile Category 2 Arthur is chewing up the Outer Banks this morning, about to brush New England.
Our lakes are looking even better.

"Advancing into July without a 90-degree max in the Twin Cities is a relatively common occurrence in the long-term record; roughly one-in-five summers. However, it is less common in recent decades: occurring only in 1974, 1981, 1993, 2003, and 2014 over the past 40 years. (see: http://climate.umn.edu/text/historical/mspmaxtge90.txt )
There have been three summers in the Twin Cities record where 90 degrees was never reached at all: 1902, 1915, and 1993. You may recall the summer of 1993. Like this year (thus far), the summer of 1993 was extraordinarily wet in the Midwest. It's interesting to note that the previous summer, 1992, reported only three 90-degree days. On average, 1992 was far colder than 1993. Similar to this year to-date, average temperatures in 1993 were propped up by elevated minimum temperatures due to the persistent cloudiness..."

- Precipitation in the Midwest has been increasing since the ’30s, including increases in overall precipitation and an increase in extreme precipitation events.
- Midwest flooding presents a major economic risk in the Midwest—the 1993 Mississippi flood was the costliest flood in modern times after Hurricane Katrina. In 2008, another flood in Cedar Rapids incurred over $10 billion in damages.
- These historic floods were caused by persistent heavy rainfall. Research shows that the trend towards heavier rainfall events has resulted in an overall increase in flood risk across the region.
- The risk of levee failure is a significant hazard, as the Midwest contains nearly 4,000 miles of levees, many of which are in poor condition.
