San Diegans can expect a mix of clouds and sun with steady warming temperatures heading into the weekend. The forecast indicates high temperatures in the coastal areas ranging from 67 to 73 degrees on Tuesday, followed by a slightly warmer Wednesday with highs around 69 degrees. Inland, temperatures are set to climb, hitting a high near the 80s in valleys and reaching into the 90s in the high desert areas, according to updates from the National Weather Service San Diego.

A statement from the National Weather Service notes that "Dry weather will continue, with breezy conditions in the mountains and deserts through today." As we look further into the week, a weak upper-level low will form over the region by Tuesday, though it is expected to have little effect on temperatures or the marine layer. Thursday is predicted to bring partly sunny skies with a high near 72 degrees, as the region sees a slow rise in daytime temperatures.

Marine activities near San Clemente Island may be affected by gusts reaching 20 to 25 knots, prompting the NWS to issue a Small Craft Advisory for this afternoon and evening. Meanwhile, beachgoers should be mindful of the potential hazards of a long-period south swell, which could produce surf up to 6 feet in Orange County, leading to dangerous swimming conditions and possibly minor tidal overflow.

While Friday is expected to be warm with an anticipated high near 73 degrees, there is significant disagreement among forecast models regarding the potential for precipitation next weekend, with about "a 45 percent chance for measurable precipitation in the SD County mtns for the 24 hr period from Sat afternoon to Sun afternoon, and about a 20 percent chance for elsewhere" according to the Area Forecast Discussion from the National Weather Service San Diego.
