Los Angeles-area temperatures will climb several degrees above normal Tuesday, reaching the 90s in the San Fernando, Santa Clarita and Antelope valleys.
Forecasters blamed the unseasonable heat on a ridge of high pressure and an offshore flow, which, though weak, is limiting sea breezes.
Downtown L.A. was forecast to hit a high of 83 degrees Fahrenheit Tuesday – – 9 degrees above normal, said National Weather Service Robbie Munroe. Woodland Hills is forecast to hit 92 — 14 degrees above normal, Munroe said — while Saugus will reach a high of 94, or 17 degrees above average.
The Antelope Valley will also experience unseasonable heat, with a high of 92 expected in Palmdale — not 78, which is normal for this time of the year, according to the NWS.
But a cooling trend is on its way, and showers are expected Sunday and Monday.
In the meantime, the NWS forecast sunny skies Tuesday and highs of 74 in Avalon; 75 at LAX; 79 in Long Beach; 82 on Mount Wilson; 83 in Downtown L.A.; 86 in San Gabriel; 87 in Burbank; 88 in Pasadena; 91 in Lancaster; 92 in Woodland Hills and Palmdale; and 94 in Saugus.
Temperatures will begin falling Friday. By Sunday, Downtown L.A. will reach a high of 67, 16 degrees lower than Tuesday. Woodland Hills will fall to 69, 23 degrees less than Tuesday, and Saugus will be at 66, or 28 degrees lower than Tuesday.
Sunny skies are also forecast in Orange County Tuesday, along with highs of 68 in Laguna Beach; 69 in Newport Beach and San Clemente; 82 in Anaheim, Irvine and Mission Viejo; 84 in Fullerton; and 86 in Yorba Linda. As of Tuesday, no precipitation is forecast in Orange County in the next six days.
