July is the peak of meteorological summer and our hottest month of the year. As the Fourth of July holiday approaches, what type of weather should we expect? 

The normal high temperature stays around 90 degrees during the entire month of July. 

After looking back at the past decade of weather in St. Louis on the Fourth of July, some of the data may surprise you.

The hottest Fourth of July was in 2012, when the mercury soared to 105 degrees. That set a new daily record high temperature, which still stands today.

The coolest Fourth of July was back in 2016, when the high temperature only hit 81 degrees. Average high and low temperatures are 89 degrees and 71 degrees. 

Three years in a row (2013–2015) had a high of 84 degrees. 

The past five years have been even warmer. We've ranged from 90 degrees to 97 degrees just two years ago. 

This date hasn’t produced much rainfall for us, with only one of the last five years recording any rain and rainfall was less than 0.2 inches.

What does this all tell us? That our Fourth of July in St. Louis is usually a dry day with temperatures likely in the 90s. How does this compare with the current forecast?

Looks like the current forecast may break the "status quo," as we have rain and storm chances. 

As for how the weather can affect a fireworks display? Lightning may be problematic to not only the spectators but also to unlit fireworks.
