Los Angeles, California – A warmer-than-normal weather pattern is expected to take hold across Southern California between Tuesday and Saturday, bringing a noticeable rise in temperatures along with an increasing chance for rain. The shift points to a more active stretch of weather after a relatively quiet period, with impacts varying by elevation and location.
According to the National Weather Service Climate Prediction Center, Southern California carries a 60–70% probability of above-normal temperatures during the January 20–24 window. At the same time, precipitation probabilities increase into the 40–60% range, signaling a growing risk for rain as Pacific storm systems move into the region.
Along the coast and across inland valleys, including Los Angeles, Orange County, and the Inland Empire, daytime temperatures are expected to run warmer than typical for late January. That warmth supports rain rather than cold-weather impacts, though steady showers could lead to slick roads and reduced visibility during peak travel times. Major routes such as I-5, I-10, U.S. 101, and State Route 91 may see slowdowns during periods of heavier rain.
In the mountains, including the San Gabriels, San Bernardinos, and higher terrain of Riverside and San Diego counties, precipitation may fall as snow at higher elevations. Snow levels could fluctuate during the week, creating changing travel conditions along routes such as I-15 through Cajon Pass and Highway 18. While widespread flooding is not currently indicated, brief ponding and minor debris flows are possible in recent burn areas if heavier rain develops.
Residents are encouraged to stay weather-aware during the Jan 20–24 period, particularly when traveling or commuting. This warm, active pattern is expected to persist through late week, and additional advisories or alerts may be issued as rain timing and intensity become clearer.
