Fire danger will build with the heat, lack of rain, and lower relative humidity. The moisture is so limited that not only don't we see any chances of rain, but we may only see a handful of clouds. That will make a huge impact on top-soil moisture, Expect the fire dangers to soar.

Our feels like temperatures are closer to our actual temperatures than normal because of the lower humidity. 

Because this is a dry heat, the evaporation rates are very high and therefore fire danger will become much greater by the end of next week, just as lightning returns to the skies.

The beaches will without a doubt have some of the best weather, just as the extreme heat is kicking in, the sea breeze will cool beach temperatures by 10°.
