San Diego area is braced for a subtle yet significant shift in weather as we inch closer to the weekend. The National Weather Service San Diego CA has forecast a slight rise in temperatures today compared to Tuesday, with coastal areas seeing mid to upper 60s. In comparison, the mountains and deserts will enjoy highs in the 50s to mid 80s. This warming trend is only poised to lightly intensify Thursday, bringing temperatures a few degrees above average.
Prepare to wake up to familiar foggy mornings as the marine layer makes a comeback, spreading a few miles inland during Wednesday morning and potentially leading to localized dense fog near the mesas. "Areas of fog," finds its way into the forecast, a reminder of the ever-present marine influence on the Californian climate. This slight warming period is to gradually bow before a strengthening onshore flow as we head into Friday, according to what the experts at the National Weather Service have to report.
However, don't get too comfortable with the mild weather. By the weekend, a low-pressure system is expected to cause a stir. "For the weekend, a low-pressure system moving inland along the West Coast will bring cooling, stronger and gusty west winds, and periods of showers from the coast to the mountains," states the Area Forecast Discussion from the National Weather Service San Diego CA. Saturday could see a significant drop in temperatures — 10 to 15 degrees lower than usual — with the desert regions feeling an additional chill on Sunday.
The weather shift could also bring some excitement to the skies. Pilots should be on the lookout for low clouds and fog disrupting visibility in coastal and valley regions this morning. Aviation conditions should remain clear for the mountains and deserts today, apart from isolated light showers in the afternoon. "Bases will be 400-900 feet MSL, tops to 1400 feet, and vis 2-5SM, locally lower," notes the National Weather Service. Mariners are also advised to expect potential hazardous conditions come Saturday night, as stronger winds and rough seas are on the horizon to possibly disrupt sea travel.
While the Skywarn weather spotter activation isn't requested, diligent observation is always appreciated by meteorologists. The weekend's looming precipitation does offer up a reminder of nature's capricious ways, a sign for residents to enjoy the warmer days before the inevitable shift to a cooler, damper spell.
