Congress has cut federal funding for public media — a $3.4 million loss for LAist. We count on readers like you to protect our nonprofit newsroom. Become a monthly member and sustain local journalism.

Wednesday's weather brings you more patchy fog and drizzle in the morning (the perfect cafecito and pan dulce weather) and some light rain overnight for areas in the L.A. basin.

Quick Facts
    • Today’s weather: patchy drizzle, afternoon sunshine
    • Beaches: 70s
    • Mountains/deserts: 60s/80s-90s
    • Inland: 70s
    • Warnings and advisories: None

The National Weather Service says there's a 20% chance of light rain for mainly the coast, coastal valleys and foothills.

Today's highs will be in the 70s for most of Southern California. Along the coast, it'll be in the low 70s and slightly breezy. It'll be a bit cooler in the mountains with temperatures reaching the upper 60s. In Riverside, San Bernardino and the Inland Empire, temperatures have dropped to the mid 70s. Highs in the low desert have dropped to the low 90s, 80s in the high desert.

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

Taking a look ahead: The cooler weather is here to stay for the rest of the week. On Thursday, strong gusts up to 45 mph are expected in Coachella Valley. If you happen to find yourself in the Mojave Desert, expect strong winds up to 30 mph on Thursday.

This day in history

On this day in 2005, numerous thunderstorms hit San Diego County and lightning strikes caused a number of tree fires from Carlsbad to Escondido.

As Editor-in-Chief of our newsroom, I’m extremely proud of the work our top-notch journalists are doing here at LAist. We’re doing more hard-hitting watchdog journalism than ever before — powerful reporting on the economy, elections, climate and the homelessness crisis that is making a difference in your lives. At the same time, it’s never been more difficult to maintain a paywall-free, independent news source that informs, inspires, and engages everyone.

Simply put, we cannot do this essential work without your help. Federal funding for public media has been clawed back by Congress and that means LAist has lost $3.4 million in federal funding over the next two years. So we’re asking for your help. LAist has been there for you and we’re asking you to be here for us.

We rely on donations from readers like you to stay independent, which keeps our nonprofit newsroom strong and accountable to you.

No matter where you stand on the political spectrum, press freedom is at the core of keeping our nation free and fair. And as the landscape of free press changes, LAist will remain a voice you know and trust, but the amount of reader support we receive will help determine how strong of a newsroom we are going forward to cover the important news from our community.

Please take action today to support your trusted source for local news with a donation that makes sense for your budget.

Thank you for your generous support and believing in independent news.
