(WZZM) - It's official!  We have reached triple digits.

The official temperature hit 100 at the Gerald R. Ford Airport at 3:08pm.  This ties the record set in 1921...and we still have a few hours yet where the temperature could still go up a degree or two.

Tonight on WZZM 13 News, we'll have updates on the heat wave, ways to keep cool for under $5 a day, and just how much it does cost to get central air conditioning in your home. 

And, what is it about the number 100 anyway?
