The Fourth of July weekend will inspire some of us, at least, to celebrate our independence from 100-degree weather.

After a heat wave that's been scorching Southern California, including temperatures near and above 100 degrees forecast for today in local valleys, a merciful cool-down could be in store, federal forecasters say.

A trough of low pressure passing to our north will work in tandem with weakening high pressure over the Four Corners to cool us down significantly, said National Weather Service meteorologist Robbie Munroe.

Monday and today are likely the hottest days of the week, he said. Tomorrow's high temperatures could drop a few degrees, followed by drops of as many as five degrees Thursday, Friday and Saturday, Munroe said.

The result could actually be below-normal temps for the Fourth of July holiday weekend.

“By Saturday we're expecting highs in the 80s for the hottest locations,” Munroe said. “Highs downtown are expected to be around the mid-70s, and closer to 70 at the coast.”


Indeed, the sad news, if you can call it that, is that beaches could be hit with cool onshore breezes and gloomy overnight clouds, which could throw shade on early evening fireworks. We'll see.

“The marine layer might stick around at some beaches,” Munroe said.

In the meantime, it will be very hot today, with temps as high as 110 in some of the high desert communities of Los Angeles County, federal forecasters warned.

“Relief from the heat can be found at California beaches, where the Pacific Ocean influence will keep highs in the 70s and 80s,” private forecaster AccuWeather said in a statement.

If you can hold on, more of that is on the way.
