As temperatures rise in Southern California, the National Weather Service in San Diego offers a glimpse of what to expect in the coming days. According to their latest forecast, we're in for a mixed bag of climbing and subsiding mercury levels.
It's sweltering out there, but not entirely consistently so. The high temperatures for today are expected to be "near average for the coast to as much as 5 to 10 degrees above average for the mountains and high desert," reports NWS San Diego, with coastal spots seeing mid-60s to lower 70s and the Inland Empire basking in mid-80s to mid-90s. However, the lower deserts will find a slight reprieve, as "low-level moisture from the Gulf of California may limit warming."
On Wednesday, a cooling of around 5 degrees is projected through Friday, bringing minor relief before the heat makes a fierce comeback over the weekend. As the National Weather Service site detailed, the forecast expects "high pressure to the south to bring around 5 degrees of warming for the weekend followed by slow cooling for early next week."
Marine influence plays a pivotal, albeit fickle, role this week. In the mornings and at night, coastal low clouds will press into parts of the valleys, then become sparse and retreat to a shallower marine layer over the weekend. As the high pressure hunkers south, Sunday could scorch the dials with temperatures "mostly 5 to 10 degrees above average." Even at the coast, folks are looking at a thermometer pushing into the lower 70s, while desert dwellers might face a sizzling range of 108 to 112 degrees, as per the National Weather Service.
Sailing through this heated spell, marine conditions will remain benign with "no hazardous marine conditions expected today through Saturday," the National Weather Service forewarns. On land, the marine layer will remain stalwart, about "1500 to 2000 feet deep through Thursday," ensuring that night and morning coastal low clouds continue to visit the valleys, though with less persistence as the weekend advances.
