A bizarre weather pattern is on tap for Michigan early next week. This strange weather will actually be courtesy of a piece of the polar vortex. Yes, that's right - our old nemesis, the polar vortex.

It is very strange for any influence of the polar vortex to happen at this time of year. Normally in summer the polar vortex is at the pole, or even almost non-existent. But the top graphic shows the upper air flow expected next Tuesday July 15, 2014 by all of our weather computer models. The circular area is an upper level storm system that will be dropping southward to be centered just north of Lake Superior.

I guess you know where I'm going with this. Next week could have some extremely chilly weather for this time of year in Michigan.

Next Tuesday July 15, 2014 will be very chilly for this time of year. This graphic shows the high temperature expected Tuesday. Most of Lower Michigan will only make it to the 60s and the U.P. will be stuck in the 50s.

How cold will it be?

Tuesday and Wednesday look like the chilliest days next week. The graphic shows the expected high temperatures next Tuesday July 15, 2014. All of Michigan should be 15 to 20 degrees colder than normal. Southern Lower Michigan could only have high temperatures in the upper 60s. Northern Lower Michigan, with places like Traverse City and Mackinaw City, could have high temperatures only around 60 degrees. Some parts of the Upper Peninsula may not even hit 60 degrees.

When we talk about cold afternoon temperatures, you may also worry about too cold of temperatures at sunrise. I wouldn't worry about that. It will be chilly with morning low temperatures in the 45 to 50 degree range. But frost shouldn't be an issue because of the Great Lakes water temperatures in the 50s and 60s. Usually in a weather pattern like this, the cold air moving over the Great Lakes will form clouds and spurts of showers. The clouds hold the temperature up from getting too cold, and the air blowing off the water helps hold the nighttime temperature up.

Waterspout weather coming?

One weather feature that this pattern could brew is a waterspout. When cold air aloft hangs above the warmer water of the Great Lakes, waterspouts can develop. Although waterspouts can be dangerous to you on the water, I find them very fascinating to watch from land. So let's keep our eyes open and our video cameras handy. We may get some neat videos to share next week.

Of course I'll remind you as the pattern gets closer. For now, get out and enjoy the sunshine today and Friday. I will be watching the chance of another fast moving complex of storms possible Sunday. These storms would happen on the edge of the cold air plunge.

New information about El Nino has just come in during the past hour. I will write about that tomorrow. You may not want to hear what I have to say.

How is this summer for you? Gorgeous or too cold and wet? Post comments below.
