If you thought April showers would bring May flowers early to Southern California, you may find the skies less generous than anticipated. According to the National Weather Service in San Diego, the region is gearing up for a subtle drop in the mercury through the rest of the week. Coastal and western valley areas slightly dip in their high temperatures, ranging from 61 to 69 degrees. In contrast, those trekking the mountains and wandering the high deserts can expect to brace for cooler winds, with highs plummeting to a brisk 49 to 81 degrees by Friday.

The weekend forecast outlines an even more pronounced cooldown, almost defying the typical springtime warm-up. "Saturday high temperatures 10 to 15 degrees below average for inland areas to as much as 20 degrees below average for the higher elevations of the mountains," according to the NWS San Diego. Moreover, the skies will darken slightly, with a slight chance for mostly light showers late Friday night into Saturday evening.

For those navigating the vicissitudes of this climate ballet, the skies over our coastal waters have played host to a marine layer deepening to 3000 to 3500 feet. This cloak of moisture will extend its reach into the valleys and paint the typically clear vistas with widespread low clouds. And as if on cue, the swaths of fog will creep onto more of the coastal mountain slopes by Thursday, bearing stronger onshore winds that'll buffet the mountains and deserts, reports the NWS Area Forecast Discussion.
