This summer has been a far cry from the heat wave of Summer 2012 as most of the midwest has not yet even seen a 90-degree day. And now, forecasters are calling for a blast from Canada that will see temperatures plummet as low as the 40s next week.

Morning temperatures early next week will likely be in the 50s for many of us, with those to the north, like Marquette, Mich., according to WSBT, maybe only reaching highs into the upper 50s on Monday and Tuesday. The forecast may be good for some, especially since the cooler temperatures will ward off any mugginess that is typical for Indiana in July.

Meteorologists say Canada, and especially Typhoon Neoguri which hit Japan this week, made the jet stream wavier than usual that will result in the coming cool down, which is expected to see temperatures nearly 20 degrees lower than normal for July.

Locally, low temperatures Monday through Wednesday nights are forecast to be in the middle 50s with highs for Tuesday through Thursday in the upper 60s to low 70s.
