Quick Facts

  • Today’s weather: cloudy and patches of sunshine
  • Beaches: 70s

In Riverside, San Bernardino and the Inland Empire, temperatures are still in the low to mid 70s. Highs in the low desert have dropped to the upper 80s, to 92. In the high desert, temperatures have dropped to the upper 70s to low 80s.

Antelope Valley and the low desert will see more sunshine than the rest of the area.

These temperatures are typical for a December day, according to the National Weather Service.

And throughout the region, nighttime lows will dip into the low 60s with more patchy fog and light drizzle.

Taking a look ahead: The below-than-normal temperatures are here to stay until tomorrow when a slight warming trend — about 5-10 degrees — begins. That will carry into the beginning of next week.

About those advisories

There's a wind advisory out for the Western and Eastern Antelope Valley foothills where southwest winds between 20 to 30 mph are expected, gusts up to 50 mph are also possible.

That's in effect from 1 p.m. to 9 p.m.

At LAist, we believe in journalism without censorship and the right of a free press to speak truth to those in power. Our hard-hitting watchdog reporting on local government, climate, and the ongoing housing and homelessness crisis is trustworthy, independent and freely accessible to everyone thanks to the support of readers like you.

But the game has changed: Congress voted to eliminate funding for public media across the country. Here at LAist that means a loss of $1.7 million in our budget every year. We want to assure you that despite growing threats to free press and free speech, LAist will remain a voice you know and trust. Speaking frankly, the amount of reader support we receive will help determine how strong of a newsroom we are going forward to cover the important news in our community.

We’re asking you to stand up for independent reporting that will not be silenced. With more individuals like you supporting this public service, we can continue to provide essential coverage for Southern Californians that you can’t find anywhere else. Become a monthly member today to help sustain this mission.

Thank you for your generous support and belief in the value of independent news.
