San Diegans feeling the summer heat are about to get a minor reprieve, according to the latest forecast by the National Weather Service. A trough of low pressure hovering over the West Coast will lead to cooler temperatures, with highs ranging 3 to 7 degrees below the norm today and expected to remain so into Monday. Breezy west winds will also be prevalent in mountainous regions and desert areas, potentially reaching 55 mph, as detailed by the National Weather Service San Diego.
For those closer to the coast, occasional low clouds and fog may mark their mornings and nights, but clear skies generally dominate the inland forecast. As cited by the Area Forecast Discussion released by the National Weather Service San Diego, "Winds will slowly weaken through the morning before strengthening again for this afternoon into tonight with peak gusts around 35-50 mph."
The cool-down should linger through Tuesday, but the weather is expected to warm up again as the week progresses. The NWS has noted an emerging warming trend beginning Wednesday that will continue through the end of the week. Moreover, the influx of monsoon moisture is anticipated by Friday, persisting into the weekend and potentially bringing thunderstorms to parts of the mountains and desert areas in the afternoons. These developments could affect outdoor activities towards the end of the week and should be monitored for updates.
Regarding travel and aviation, coastal marine layers may challenge visibility through mid-morning, with low clouds drawing upwards to 20 miles inland by 15Z, per the NWS Aviation report. Conditions are set to improve later in the day, promising clear skies for the mountains and deserts, at least for now.
Meanwhile, those at sea can breathe easy as no hazardous marine conditions are expected through Wednesday. This stable weather, however, could pivot as the weekend approaches, making those plans for a sailing excursion potentially subject to the thunderstorms that might roll in with the returning monsoon moisture. Active Skywarn participation is not required, but spotters are encouraged to report significant weather conditions, signaling a community effort to stay ahead of the changing climate patterns in the region.
