Hot Spell In San Gabriel Valley: Baldwin Park

BALDWIN PARK, CA — Expect balmy beach temperatures at the coast and warmer than normal temps for inland Orange County midweek. A ridge of high pressure will limit the press of sea breezes into the southland giving Los Angeles County, San Gabriel Valley and Riverside County a bit of a hot spell, the National Weather Service said, Tuesday.

Inland Orange County and Los Angeles-area temperatures will climb several degrees above normal Tuesday, with mountain temps in the mid-80s, and temperatures 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. At the coast, it will be perfect beach weather but inland temperatures will be higher than normal for early May.

Sunny skies are the forecast in Orange County Tuesday, along with highs of 68 in Laguna Beach; 69 in Dana Point, Newport Beach and San Clemente; 72 in Seal Beach; 74 in Laguna Niguel and Los Alamitos; 76 in Fountain Valley and San Juan Capistrano; 78 in Ladera Ranch; 82 in Anaheim, Irvine, Lake Forest, Mission Viejo and Rancho Santa Margarita; 84 in Fullerton; and 86 in Yorba Linda.

As of Tuesday, no precipitation is forecast in Orange County in the next six days.

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.

Don't worry. A cooling trend is on its way, and showers are expected Sunday and Monday for part of the southland, NWS claimed.

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 Arcadia, Diamond Bar, Glendora and Pasadena; 89 in Baldwin Park; 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.
