Very unusual heatwave eyes Michiana, Midwest next week
When you factor the high humidity values into the equation, you get "feels like" temperatures that are even hotter than the actual air temperatures.We're likely going to see "feels like" temps in the lower and middle 90s each afternoon between Tuesday and Thursday. The absolute hottest heat indices locally will likely range from 94° to 96°. Parts of southern Illinois and Indiana will make a run at the century mark!
To put that into perspective, South Bend has only had a heat index at or above 95° in September 11 times since 2010. That averages out to about one September day per year with a heat index of 95° or higher.While this won't be the worst heat we've seen this summer, it will be the worst we've dealt with since early August.
It'll also be hot enough to cause sunstroke, muscle cramps and heat exhaustion if you don't take appropriate action. When heat indexes rise to 90-105°, it is encouraged to use "extreme caution" when outside.
Wearing light-colored, loose-fitting clothing, staying hydrated, taking frequent breaks in air conditioning, and limiting extended time in the sun are all precautions you can take to stay safe.Fortunately, it does cool down to at least "average" levels by next Saturday. However, all signs point toward temperatures remaining above normal for the foreseeable future. Hopefully you weren't done with summer quite yet!
