I was joking with a colleague last week that it will not be long before we see advertisements for back to school specials. Some colleges begin classes in August. Apparently Mother Nature had the same thought as she tossed autumnlike weather our way.
After a week of very warm temperatures a shift in the jet stream has funneled cool air into the Great Lakes region. The satellite image from midday captured the cloud features that we often see in late September when the first intrusion of autumn air tumbles out of Canada.
We started the meteorological summer on June first and had a very chilly couple of days with highs only in the 50s. Last week we recorded three days of 90 degrees or better in the Twin Cities. With highs only in the 70s today and Tuesday we will end up about a degree or two below the thirty year average for the month of June.
