Excessive Heat Warning will make for scorching Fourth of July this year 

Updated July 04, 2018

The Miami Valley will be heating up this Independence Day! A week spent near 90 degrees will continue for the holiday.

Excessive Heat Warning in effect Wednesday from noon until 8 p.m. for Butler, Warren, and Clinton counties. The warning is extended for Montgomery county until 8 p.m. Thursday. (Heat Index of 105-110 degrees)

A weak boundary will weaken and drift south Tuesday but it won’t do much to make us any cooler. Highs are expected to be in the low 90s with the heat index above 100.

Many communities have festivities all day with fireworks in the evening, here’s what you need to know. 

Heat Advisory from noon until 8 p.m. Wednesday for our entire viewing area. (All Counties) The advisory is extended for Butler, Warren, and Clinton counties until 8 p.m. Thursday. (Heat Index of 100-105 degrees)

For the Afternoon: 12PM-5PM

     
  1. The UV Index will be very high so even with some scattered clouds, sunscreen is needed all day. 
  2. A pop-up storm could develop but most will stay dry. 
  3. The temperature will be about 10 degrees warmer than normal reaching the low 90s in the afternoon. 
  4. It will not only be hot but also HUMID. This combination will take the heat index up between 100-105. The heat index is a value that shows how hot it will feel. It is important to look at how humid the air is this time of year because when our bodies heat up, they start to sweat. If there is a high moisture content to the air it makes it harder for the sweat to evaporate and that cools our bodies down.
