The weather these past couple of days has been brutal. Breaking record highs for several days, the most impressive day was June 4.

We previously had a record of 103° set back in 1990, and this year we topped it with a scorching 107°.

Friday, isn't going to be the same. We are still expecting to see highs well about 100°, but no record highs to report.

So why have we been seeing this insanely hot weather lately?

Picture it like this. We have a strong high pressure system above us. This system acts like a shield, it won't let in any cool fronts, any moisture or strong winds.

We are basically being shielded from shade, and its letting the sun just beam down on us.

Good news is, we will soon see this high pressure move to the east, allowing a cool front to move in. But because we have just been baking for a while, the cool air won't be enough to bring down our temps.

Highs will dip down to the upper 90's by Sunday thanks to the cool front,  but it will be a little difficult for us to feel the difference between 105° and 99°.

Thankfully, the heat advisory is expected to expire Friday at midnight, and no it's not some kind of Cinderella fable.

There is actually a scientific reason as to how and why a heat advisory is issued and how to know when it expires.

A heat advisory is issued at the point when the temperature is expected to reach or exceed 105 degrees. Last Monday, we were definitely in that temperature range.

During the night, the heat advisory has certain guidelines as well. If the overnight low is at 75 degrees or greater, the heat advisory continues, but if the temperature is expected to be in the upper 60's most of the time meteorologists will cancel the advisory.

In the case of Friday, our expected overnight low is in the 75° range, and that is why the heat advisory will remain in affect until midnight.

Temperatures will be around the century mark on Saturday and Sunday, dip into the 90's on Monday and then once again heat up to the 100's by Tuesday.

At this point it's not looking like those highs will surpass or reach the 105 degree mark.

This wont be the only heat advisory we will see this year. Temperatures will be heating and cooling all summer long, and  I know at this point you are drowning in facts on how to stay safe during a heat wave.

But it's a good idea to continuously be repeating information, in the hopes that some of it sticks and helps save a life this summer.

Did you know: Each year, heat kills 1,500 people on average in the United States — more than tornadoes, hurricanes, floods, lightning, or any other weather event combined. (NOAA)

Also, people like city-dwellers and those living in the upper floors of tall buildings or in heat-prone regions are most at-risk for heat-related illness.

People who have difficulty getting around or who have health conditions are particularly susceptible. 

The National Oceanic and Atmospheric Administration has done a good job on listing the do's and don'ts for this summer.
