After an unusually hot stretch in March and early April, Southern California is set to experience a shift in weather patterns, with cooler temperatures and a high chance of rain expected to arrive by Friday. The National Weather Service forecasts that inland areas will continue warming through Wednesday before a cooling trend settles in, bringing showers and a slight chance of thunderstorms late Friday into Saturday.

Why it matters

The upcoming weather change comes after a period of record-breaking temperatures and elevated fire danger in the region, highlighting the importance of monitoring and adapting to shifting climate patterns. The potential for significant rainfall and mountain snow could also impact transportation, outdoor activities, and water resources in the area.

The details

Forecasters say a low-pressure system is expected to increase the chance of showers late Friday into Saturday, with rain chances across the region around 80% for the weekend. Mountain areas have about a 30% chance of seeing an inch or more of rain, while lighter amounts are expected closer to the coast. Southwest to west winds of 35 to 45 mph are also expected in mountain and desert areas Thursday and Friday, and snow levels are forecast to drop to around 6,500 feet late Saturday and near 6,000 feet by Sunday, potentially bringing light accumulations to higher elevations.
