The National Weather Service in San Diego reports a slight uptick in temperatures for the region, with today's highs forecasted to be a few to around 5 degrees warmer than Tuesday. Coastal areas of San Diego County can expect temperatures ranging from the lower to mid-70s, while inland valleys are likely to experience upper 80s to mid-90s. Orange County is similarly positioned, with lower to mid-70s near the coast and upper 80s for inland areas, according to the National Weather Service.

For those traversing the Inland Empire, the weather predominantly sits in the 90s, giving way to mid-90s to 106 in the Apple and Lucerne Valleys. The lower deserts are projected to feel the heat intensely, with temperatures predicted to rise between 105 to 110 degrees. In contrast, the mountain regions from 4500 to 7000 feet are expected to enjoy a milder mid-70s to mid-80s. There's not much change anticipated for Thursday, save for the lower deserts slated to climb a few degrees warmer, topping at 112 degrees, as reported by the NWS Forecast Office.

Regarding weather patterns, the National Weather Service indicates a minor increase in monsoonal moisture today, which is expected to fall again on Thursday. Moisture levels are set to rise from Friday to Saturday, presenting a 10 to 20 percent chance of thunderstorms for mountainous and desert areas today. Thursday's thunderstorm chances dip to less than 10 percent but bump again to less than 15 percent on Friday. Come Saturday, those odds increase to a 15 to 25 percent chance.

As we look towards the weekend, model guidance shows this surge in monsoonal moisture peaking on Saturday, but it should begin to dry out and start a gradual cooling trend through the following week. Saturday highs could reach 5 to 10 degrees above the norm for inland locales. However, by Tuesday, temperatures may settle back down to near-average levels. Coastal dwellers may continue to notice low clouds from the ocean at night and in the morning, extending a touch inland each late night and early morning.

Unrestricted visibility is expected in the mountains and deserts for navigators of the skies. However, according to the National Weather Service aviation forecast, only a "15 to 20 percent chance of TSRA possible over the mountains" is expected from Wednesday afternoon into early Thursday. As for the marine outlook, no hazardous conditions are on the radar through Monday.

Lastly, the NWS calls for attention from beachgoers in Orange County, potentially predicting an incoming south swell will generate elevated surf conditions late Thursday and Friday. This swell could bring surf heights of 4 to 6 feet to south-facing coasts, heightening the risk of strong rip currents before subsiding into Saturday. While Skywarn activation is not requested, weather spotters are encouraged to report significant conditions as they arise.
