Your SoCal Weather Report For Aug. 28 - Sept 1: A Hot Start To The Week, Followed By A Slight Cool Down

It's Wednesday, and forecasters say that while it's going to be another hot day, we can expect a slight cool down come this evening.

Along the coast, highs will be in the upper 70s to low 80s and up into the 90s in coastal valleys. The valleys will see highs in the upper 90s, up to 104 in the San Fernando Valley.

The Santa Monica and San Gabriel mountains will see highs in the 90s and over in San Bernardino County, mountain temperatures will be slightly cooler in the upper 80s.

The high desert will see temperatures in the low 100s and over in the low deserts, temperatures have slightly dropped to 114 in Coachella Valley.

Meteorologist Todd Hall with the National Weather Service says the second half of the week should feel more pleasant, with an expected increase of air flow from the ocean.

"That will translate a little bit more inland each day through Thursday. We're going to be above normal until Wednesday and then we'll start to see that cooling trend really kick in on Thursday as we see the return of low clouds and fog starting at the coast and beaches."
