An article on mlive.com today is warning us of colder temperatures heading to Michigan next week. Typically, we talk about cold temperatures in July, and refer to the lower 70's. Well, it appears that this is a tad more of an extreme situation...The Polar Vortex is expected to dip south next week, keeping Michigan 15-20 degrees below normal. The article shows graphic displays of where the Polar Vortex will be situated and the odd course of the jet stream. Early temperature models show us in Lansing struggling to get to the upper 60's. Meanwhile, Northern Michigan will see temperatures in the mid 50's to lower 60's...those are high temps...IN MID-JULY!!!! For the farmers and green thumbs, this could cause some worries about the potential for frost at night. The article tries to put those worries to rest, citing overnight lows in the mid 40's to lower 50's. The water temperature of Lake Michigan is credited for keeping the frosty temperatures at bay. But, this also creates good conditions for waterspouts on the Great Lakes, as warmer water temps fight with cooler air temps. Get ready!!! Tuesday and Wednesday won't exactly be bikini weather, ladies...unless you have some glass that needs cutting...
