For those enjoying the Southern Cali rays, brace yourself for a slight cool-down midweek. According to the National Weather Service, San Diegans will experience a gentle tick downward in temperatures on Wednesday. Beach-goers can expect to bask in mid to upper 60s while valley-dwellers experience a range from 70s to around 80. Don't pack away those shorts just yet, as Thursday promises a nudge back to the warmth with similar conditions and not much change for the mountains and deserts.

Looking inland, the weather roulette continues. The Apple and Lucerne Valleys will simmer in the mid 70s to lower 80s both days, with the lower deserts predictably baking in the upper 80s to mid 90s. Sitting at altitudes of 4500 to 7000 feet, mountain residents are kissing the 60s with a touch of lower 70s. However, it's not all steady as she goes; a "weak coastal eddy at times" could throw a minor wrench into the predictable patterns, the National Weather Service's Area Forecast Discussion reports.

San Diego's coast and valleys are caught in a weather tango, swinging between slight warmth and moderated cool as the week unfolds. But the true shift comes cruising in over the weekend. "Slow cooling will begin to spread inland on Friday," the National Weather Service states. As onshore flow flexes its muscles, notable cooling sweeps across the region Saturday and Sunday, with Sunday marked as the "coolest day with the strongest west to southwest winds for the mountains and deserts."

While a reprieve for some, this cool wave won't bring any substantial downpours. Forecasts looking toward Sunday hint at a possibility of light precipitation, but keep those picnic plans. The numbers crunch whispers a less than 10 percent chance for measurable rain, so the umbrella salesmen might have to wait another day. The NWS' marine forecast echoes calm conditions, ensuring seafarers and anglers that no hazardous marine conditions are expected through Friday. Beyond that, early next week aims to bring back the warmth with "weaker winds for early next week" as the fleeting pressure system moves along, leaving SoCal to bask once more in its typical sun-soaked state.
