The National Weather Service San Diego reports that the cooling trend continues to sweep through the region. Temperatures will plummet, diving as much as 8 to 12 degrees below average for valleys and inland Orange County, with the lower deserts hanging on to warmer climes just a few degrees below the norm. Coastal areas can anticipate highs between 60 to 64 degrees, while western valleys and inland Orange County may see temperatures ranging from 61 to 65 degrees today. According to NWS San Diego, the shift doesn't stop there. Thursday promises to bring further chills, particularly to the mountains, nosediving to as much as 10 to 15 degrees cooler than Wednesday.
Wind patterns won't be shy either, with the forecast indicating areas of stronger and gusty southwest-to-west winds. Think of it as nature's bluster, causing a fuss for the mountains and deserts from this afternoon into Thursday night. Expected gusts will barrel through at speeds of 40 to 50 mph, and adventure seekers warned that isolated gusts could crank up the excitement to a howling 55 to 65 mph.
Looking ahead, the cool and cloudy reprieve promises some drizzle with the potential for light rain as two different low-pressure systems take a tour through Southern California. The first low pressure, making its entrance from the west, is set to usher in chances for showers starting late tonight and into Thursday morning. In contrast, the second, arriving from the north, looms for Thursday night into Friday, the Area Forecast Discussion states. The marine layer has deepened and might grace the coastlines and valleys with patchy drizzle this morning, although the probability for measurable precipitation remains below 20 percent.
Those residing in or traversing the mountains gear up; snowflakes might dance in the skies come Friday. The snow level is projected to drop to around 6500 feet, with a slight chance of accumulation above 7000 feet—maybe an inch or two should winter decide to take one final bow. Weekend warriors can look forward to a dry and warmer atmosphere, as temperatures are expected to tiptoe back to near average. Coastal dwellers will soak in milder mid to upper 60s, while the Inland Empire basks in mid-70s to lower 80s on Sunday. Our desert companions, however, will sizzle around 90 degrees.
Aviation forecasts from the National Weather Service predict low clouds scattered throughout the coastal basin into the coastal mountain slopes, affecting visibility and creating potential flight stumbling blocks with bases between 2500 and 3500 feet and tops to 4500 feet. Significantly, after 02Z tonight, similar conditions are expected to return, with low clouds engulfing the coastal basin yet again. The coast is clear for mariners, as no hazardous marine conditions are anticipated through Sunday, ensuring smooth sailing.
