It's only the first week of meteorological summer (June-August), but high temperature records are falling by wide margins in Minnesota and southern Wisconsin.

The 103° at Minneapolis as of 3:26 pm CDT smashed the old record for June 7 in 2004 by 8°. This was also just 1° below the all-time June record of 104° set on June 27th, 1934. The National Weather Service also reports that this was:

• The first 100°+ reading since July 31, 2006.
• The first 103°+ reading in almost 23 years, since July 31, 1988.

Today's record high follows a record high yesterday (June 6) of 97°, beating the old high of 95° in both 1987 and 1979.
