The National Weather Service (NWS) Forecast Office in San Diego has detailed a warming trend for the region, with coastal areas experiencing lower to mid-70s and inland valleys hitting the mid-90s to 102 degrees today, progressively rising through Saturday; the numbers suggest temperatures will rise around 5 degrees above average for inland spots, as noted by the National Weather Service. Additionally, there's a chance of showers and thunderstorms across the mountains, deserts, and far inland valleys during Saturday's afternoon and early evening hours, bringing a slight reprieve to the rising mercury.
In line with these forecasts, residents in the Inland Empire can expect temperatures upwards of the mid-90s to 105. In contrast, the lower deserts brace for 107 to 113 degrees, culminating in a peak heat risk on Saturday, where certain areas could grapple with temperatures near Heat Advisory and Excessive Heat Warning thresholds. The forecast office suggests isolation of showers or thunderstorms increases for Friday afternoon and scaling up to a 25 to 35 percent chance for Saturday, after which a gradual drying trend is predicted starting Sunday into the next week. However, we continue to see coastal clouds in the evenings and mornings.
Concurrently, in the aviation sector, visibility concerns stem from coastal and valley low clouds, which are expected to spread 10-15 miles inland through early morning, according to the Area Forecast Discussion released by the National Weather Service. These clouds are due to lift later in the day. Still, they will likely return in the evenings, perpetuating a cycle of visibility and travel considerations, especially for the coastal areas, which may see the stratus linger further into the afternoons.
Maritime and beachgoers are not exempt from nature's ebbs and flows; with no hazardous marine conditions projected through Monday, beach activity may heighten, yet a south swell arriving Friday poses an elevated surf risk, specifically along south-facing beaches in Orange County, contributing to a moderate to high risk of rip and longshore currents across all beaches, making it essential for beachgoers to stay vigilant in the face of seemingly serene seas.
