We are looking at having a hot end of June and start of July. The hottest end of June and start of July was back in 2012 when Grand Rapids had 2 hot heat waves the first one was from June 27th until July 9th with highs of 90,97,89,89.91,96,96,99,101,104,99. There was a “break” on the 10th when the high was still a warm 86 and then from July 11th to the 18th highs reached 89,90,94,91,97,99, and 91. I guess our warm weather expert Mookie would call that one heat wave and in this case I would agree. (I would not tell him/her that)

It is now 1 AM and the current temperature here and at the airport is 82° the airport has a current DP of 76° and a reported heat index of 89° with a SW wind at 10 MPH. The record warmest minimum for today is 76° in 1931 and at this time that record is in play.

Any way stay cool and have a great 4th

A decent summer day…94 for the high?. Just right. “Heat Index”?…nothing more than the weather department’s new “gig” to help market the weather. If the temp reaches 94, then it is simply 94 outside…regardless of the flashy graphics, and a bored weather clerks random software formula.

It got to 93 degrees in Hudsonville today. The heat is oppressive. The air feels so heavy.

Will this be the hottest weekend of the summer? I sure hope so. We pretty much spent the whole day in the lake. The water is very warm, but cool relative to the air temp. Thank goodness for the breeze today. This was the definition of oppressive. I see heat indices of 100+° at every corner of the state. We won’t forget about this one for quite some time.

What was the actual high temp in gr today? Do it even get above 93 degrees. It was another nice day on the golf course and then a dip in the pool. Welcome to summer!
