Southern California to experience significant warm temperatures

Southern California is set to experience a significant warmup as spring begins. Starting Friday, temperatures are expected to rise above normal, with some areas reaching the 90s by Monday. The National Weather Service reported that winter's cool temperatures are now over. Meteorologist Bryan Lewis stated that this warm weather will be welcomed by those who enjoy the heat. He noted that the upcoming highs will be the highest of the month so far. In downtown Los Angeles, temperatures could hit 86 degrees or more by Monday, while the average for this time of year is usually in the low 70s. In some coastal valleys, temperatures may rise as much as 20 degrees above average, potentially reaching the low 90s. Other areas, such as Riverside and Palm Springs, are also forecasted to reach the 90s on Monday. Most of the surrounding region will likely see highs in the 70s and 80s, still above the typical seasonal averages. The warm temperatures are caused by a ridge of high pressure settling over the area. Additionally, northerly winds are expected to bring warmer and drier air, contributing to the heat, although they are not classified as Santa Ana winds. However, by Wednesday, temperatures will begin to drop again, though not drastically. Lewis mentioned that by mid to late week, temperatures will return to near normal levels, possibly remaining slightly elevated.
