San Diegans should brace for the juxtaposition of an imminent warming trend and a forecasted shift towards wetter conditions in the latter half of the week. The National Weather Service in San Diego reports that continued Santa Ana winds are expected to peak near 50-60 mph through Tuesday, with coastal areas preparing for a warm surge, with temperatures potentially reaching the 70-degree mark.
Amid the gusty winds, blowing dust could potentially reduce visibility, particularly near the mountains, as the stronger winds are expected to reach their peak during the afternoon hours. This wind pattern, driven by a high-pressure system over the Great Basin, is expected to usher in temperatures over 75 degrees for some East County areas in San Diego by Tuesday, with a 50-60% chance of occurrence, according to the National Weather Service in their area forecast discussion.
However, the clear skies will be short-lived, with cloudier skies and a strong possibility of rain by New Year's Eve. According to the 7 Day Forecast for San Diego, we're expecting a 30% chance of showers starting late Tuesday night, with precipitation chances escalating to 60% on Wednesday and a strong 90% by Wednesday night into New Year's Day.
While the week initiates with higher temperatures, an area of low pressure approximately 1,000 miles southwest of San Diego is forecasted to introduce subtropical moisture to the region, as the weather service anticipates mainly light showers increasing throughout Wednesday. With the heaviest rainfall predicted to fall late Wednesday night into Thursday morning, the subsequent low-pressure system, slated to arrive by the weekend, could bring the most significant precipitation closer to the LA Basin.
