High temperatures to make way for cooling trend
While high pressure is expected to dominate Thursday and Friday with a limited marine layer and warm temperatures, low pressure was expected to move more marine layer onshore over the weekend, said Bonnie Bartling, a weather specialist with the NWS in Oxnard.
Temperatures were expected reach to 99 degrees Thursday in some locations, such as Woodland Hills and Palmdale, down from triple-digit highs registered Wednesday.
Burbank should get up to 92 degrees Thursday and downtown Los Angeles 83 degrees.
Maximum temperatures would drop everywhere by Friday with the biggest declines occurring in valley areas, where temperatures were forecast to drop by two to three degrees, Bartling said.
The region is experiencing “a battle between low and high pressure,” with “one trying to influence the other, pushing each other back and forth,” she said.
High pressure would win the battle Thursday and Friday, weather officials said.
The high pressure was expected to create a mild "sundowner" wind condition in Santa Barbara County, according to the weather service predictions.
The sundowners, which bring fierce Santa Ana-like winds as the sun sets, have triggered several ravaging fires along the region’s mountainous east-west coastline.
