Rain and Snow Ahead: What to Expect After Southern California’s Heatwave

Southern California Braces for Spring Storms

LOS ANGELES – Southern California is shifting from a recent heat wave to a series of spring storms, starting Thursday. Following temperatures that reached 10 degrees above average on Wednesday, a low-pressure system is set to bring cooler air and much-needed precipitation through early next week.

The National Weather Service (NWS) has confirmed that two storm systems are poised to impact the region. The first, expected late Friday into early Saturday, is a weaker system that will initially affect Northern California and Oregon before reaching Southern California.

A stronger cold front is anticipated on Sunday, bringing significant changes. Snow levels are projected to drop from 7,500 feet to as low as 4,500 feet by the end of the weekend. Wind gusts may reach 50 mph in the interior mountains and foothills, likely triggering wind advisories.

Rainfall amounts are anticipated to be widespread, ranging from 0.50 to 1.50 inches, though local variations may occur. The first wave of light rain is expected to arrive Friday afternoon, primarily impacting coastal areas, while the second storm could deliver heavier showers and mountain snow, accompanied by a 15-30% chance of thunderstorms.

NWS forecasters are monitoring the possibility of thunderstorms that may trigger debris flow thresholds, particularly in areas affected by recent wildfires. There’s also potential for additional rain later next week.

As the weekend unfolds, residents can expect the following timeline:

• Thursday – Friday: High clouds will increase as temperatures begin to cool.
• Friday Afternoon – Saturday Morning: The first wave of light rain arrives.
• Sunday – Monday Morning: The second, colder storm delivers heavier precipitation and mountain snow.
• Tuesday: Skies are forecasted to clear, leading to dry and seasonable conditions.

Residents are advised to prepare for wet conditions this weekend, which may cause travel delays. It’s also recommended to secure outdoor items due to expected high winds and to practice road safety by avoiding flooded roadways. Monitoring local NWS updates for debris flow alerts and wind advisories is encouraged.

The second, stronger system is projected to persist into early Monday morning before clearing. Following the storm, a cooler weather pattern is expected to settle in.
