Unusually (Even Historically) Cold Mid-August MorningAugust 15th, 2014 at 2:11 pm by Chad Evans under Chad's WLFI Weather Blog
It was one unusually (term “historic” would even apply) cold mid-August morning with patchy, locally-dense fog.
Compare this morning’s low temperatures to the historic lows of mid-August 1964. The only other August with near chill like 1964 was 1962 & 1965.
Unlike 1964, the coldest weather in the Midwest & Great Lakes was centered right over our northeastern counties. Michigan was warmer than we were. A strong surface high & that pool of very dry air with it (& perhaps even the dry soils in this area) led to the dramatic, unusual & downright historic temperature drop.
In 1964, the temperature dropped to as low as 26 in Minnesota & the growing season ended extra early in parts of that state, Wisconsin & Iowa. That was not the case at all this time.
39 was recorded at several Mesonet stations, our Winamac & Burlington units & the Cass County Airport AWOS unit.
