Fourth of July ushers in weather pattern change

Posted: Updated:
(3TV/CBS 5) -

The Fourth of July marks a brutal period of weather typically in the Valley. The last week of June and first week of July are typically our hottest weeks before the monsoon season arrives with relief. This year will be no exception.

High temperatures in the Valley will peak just shy of the 110-degree mark on Wednesday afternoon, falling to the upper 90s by the time fireworks shows begin just after 9 p.m.

That stacks up pretty close to normal when you look at the historical averages. The normal high for July 4 in Phoenix is 107. We typically don’t see any rain on the Fourth. In fact, it’s only rained 18 times on the Fourth since the National Weather Service began keeping records in 1896! 

We do have rain in the forecast later in the week.

Our seasonal monsoon pattern is set to take shape starting Thursday and lasting into early next week at least.  Hopefully, this brings measurable rain to the high country where drought conditions led officials to cancel many fireworks displays this year. 

Here’s a look at how much rain typically falls during monsoon season in the high country:

    The Fourth of July is typically a hot and dry holiday in Arizona.  And while that will be the case this year, a big weather change is headed our way later this week.
