Drizzle could dampen Southern California on Monday and Tuesday before a heat wave arrives just in time for Mother’s Day weekend \u2014 with thermometers possibly reaching 90 degrees in Downtown L.A. on Sunday.<\/p>\n
Light rain is likely in the eastern San Gabriel Mountains and neighboring foothills and the Central Coast, but totals should remain less than a quarter of an inch, with “many areas seeing little or no rain,” the National Weather Service office in Oxnard said. <\/p>\n
Expect cloudy and cool conditions, similar to a “very deep marine-like layer,” the weather service said. “Temperatures will remain well below normal with highs in the upper 60s.”<\/p>\n
Temperatures in Downtown LA and Burbank could reach 67 degrees on Monday. That’s down from the May 4 average of 73 for downtown and 75 for Burbank, according to meteorologist Andrew Rourke with the weather service’s Oxnard office. <\/p>\n
Elsewhere on Monday, San Clemente could see a high of 64 degrees; Los Angeles International Airport and Escondido, 66; Oceanside, Ontario, Riverside, San Bernardino and San Diego, 67; Anaheim, 68; Long Beach and Irvine, 69; and Woodland Hills, 70. <\/p>\n
Rainfall up to one-tenth of an inch is possible in Orange County, the Inland Empire and San Diego between Monday night and Tuesday afternoon. Other parts of San Diego County may see a little more rain, such as Oceanside, which could see about a third of an inch of rain. <\/p>\n
There is a chance of afternoon and evening thunderstorms across the Sierra Nevada and Central Valley on Monday and Tuesday, and snow across some mountain passes in Mono County. There is also a slight chance of light rain and drizzle in the San Francisco Bay Area, with up to a half-inch of rain possible in the North Bay Monday night into Tuesday morning. <\/p>\n
By Wednesday the temperature starts rising, by Friday the heat is in full swing. On Mother’s Day, there is about a 50% chance that temperatures will be 90 degrees in Downtown LA and 100 degrees in the neighboring valleys. <\/p>\n
The San Diego Valleys could have been at a high in the 80s; Inland Empire, close to 90; And in the lower desert, more than 100 degrees, the weather service office in San Diego said. <\/p>\n
This is enough to pose a moderate risk of heat-related illness to pets, livestock and heat-sensitive people throughout Southern California. <\/p>\n
By Saturday, temperatures could reach the 90s in the Central Valley, with temperatures reaching 92 in Bakersfield and Fresno; Sacramento, 91; and Stockton, 90. <\/p>\n
