After a cool and cloudy weekend, Southern California is likely to see heat return next week, particularly in inland areas, valleys and deserts, forecasters said.
Eric Boldt, a meteorologist with the National Weather Service in Oxnard, said the heat wave will likely be the hottest of the season, with some areas spiking temperatures of 20 degrees Celsius or more. Some inland areas could see temperatures in the triple digits as early as midweek.
The coastal areas and most of the Los Angeles metro area “wouldn’t be that hot — almost 10 degrees above normal,” he said. For example, while the temperature in downtown LA is normally around 75 degrees Celsius this time of year, temperatures are expected to be closer to 85 degrees by the end of next week.
Over the weekend, cooling onshore winds will create coastal vortices, pulling low clouds and fog inland at night and in the morning in a typical seasonal pattern, with temperatures ranging from high in the years 60s to mid 70s along the coast. Early June is the darkest time of year in Southern California, but that is forecast to change dramatically over the next few days.
The six- to 10-day forecast from the National Oceanic and Atmospheric Administration shows above-normal temperatures across the West. Much of Southern California is expected to experience above-normal temperatures this time around.
High pressure in the eastern Pacific – where it has been unusually strong and persistent over the past two years – is expected to move over California next weekend, then into the Southwest and gradually east. , said Alex Tardy, a meteorologist with the weather agency for the City of San Diego.
The high pressure peak is expected to increase as it moves over inland Northern California and into the Western Intermountain, forecasters said, with highs rising from 10 degrees above normal on Tuesday to 20 degrees. than usual on the weekend. Central Valley can expect triple-digit heat on Thursday and Friday.
But before the heat sets in, Northern California is looking for opportunities for widespread rain this weekend, particularly Saturday and Sunday nights, the weather service said.
UCLA climate scientist Daniel Swain tweeted: “It is quite rare to see some potential for meaningful June rainfall in parts of NorCal before the heat wave is just as prolonged and potentially record-breaking. a few days later”.
Any rain is welcome, but it will take more than a few showers to ease the ongoing drought in California. The most recent U.S. Drought Monitoring data, released on Thursday, showed that nearly 12 percent of states are classified as being in extreme drought.
Much of the worst of this area lies within the makau – a hook-shaped piece of land – that covers the southern Sierra Nevada and surrounds the southern end of the San Joaquin Valley. Another narrow slope is located at the easternmost tip of San Bernardino County, on the Nevada border.
Nearly half of California – 48% – is in an extreme drought, the second worst of its kind. Another 38% are in severe drought, and 2.3% are in moderate drought, primarily in the western half of San Diego County. The remaining 0.14% is considered abnormally dry.
With the exception of parts of the Pacific Northwest, the entire continental United States west of the 100th meridian, as well as more than half of Texas and parts of the Central and southern Plains, lie in areas where the The drought is forecast to develop, continue or worsen through the end of August. Southern Arizona and southwestern New Mexico are expected to improve as monsoon intensification is forecast this summer.
Strong high pressure, like what’s expected to blanket the region next week, squeezes the marine layer, the protective heat shield that normally protects coastal California from the sun’s power when it’s highest in the sky. sky (summer solstice is June 21). Without this layer of cloud cover, temperatures would likely rise with the need for evaporation – or the thirst of the atmosphere – to draw moisture away from soil and vegetation and increase the risk of fire.
According to Miguel Miller, another meteorologist with the weather agency in San Diego, there is an element of uncertainty as high pressure will press down on the atmosphere and warm the air next weekend in Southern California.
Beneath the crest of the high pressure extending into the West Coast from the eastern Pacific, models show a low-pressure reverse trough approaching off Baja. The air rising from this low-pressure system could weaken the dominant high pressure enough to sustain a slightly stronger sea layer west of the mountain range.
