Record low high temperatures are forecast for southern Wisconsin on Friday as a very cool Canadian air mass covers the region.
The high on Friday is only expected to be in the low 60s, which would be under the record coldest high temperature in Madison for July 17 of 67 degrees, set in 1900.
Saturday's high is expected to be in the upper 60s, which could challenge the record coldest high temperature for July 18 of 68, set in 1924.
Al Gore will probably say the cause is global warming.
