Despite average temperatures to began the month of July, warmer temperatures near 100 degrees are beginning to slide across inland Southern California.
That heat will really be felt next week, when temperatures in inland areas in Southern California could rise above 110 degrees. Areas closer to the coast, such as San Luis Obispo, could see high temps well into the 80s and 90s. The onset of warmer temperatures will first be marked by phrases of clouds and humidity.
Monsoon moisture moves in soon

Temperatures along the coast could touch 70 degrees as the onshore breeze slows. It’s a pretty normal day, with the caveat that the weakening marine layer allows temps to get a bit warmer than usual.
The pattern grows in the days following. Across the western and central United States, another “heat dome” is beginning to take shape. A heat dome is a self-reenforcing mass of high pressure in the upper atmosphere that dominates the sky for thousands of miles. Just as a heat dome brought record-hot temps to the eastern U.S. last week, this heat dome – on our side of the country – will bring hot temps our way.
The heat dome will begin to take shape this weekend, with its center located around Wyoming by Sunday and early next week. Given its location to our northeast, it will drive a warm southeasterly breeze – carrying moisture from the Pacific Ocean – across California and the southwestern U.S…
