Area Forecast Discussion National Weather Service San Diego CA 253am PST Sat Feb 15 2025 Synopsis Dry weather is expected through next week. Weak offshore flow will occur below mountains passes and coastal foothills this morning through Sunday morning for warmer weather. A brief cooling is expected early next week with increased onshore flow, then minor warming and another round of weak offshore flow for the middle to latter part of next week. For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties Showers have ended across the area this morning with low clouds mostly clearing out. Patchy shallow radiation fog may develop across the valleys later this morning, clearly out by around 8 AM. Surface pressure gradients are nearly neutral to the high deserts but trending offshore. Weak northerly winds will develop along the foothills and below the Cajon Pass later this morning with local gusts around 30-40 mph. Weaker offshore flow will prevail this afternoon into Sunday morning, with a sea breeze returning by Sunday afternoon. Otherwise gradual warming through the weekend with high temperatures around 3-7 degrees above normal by Sunday. An upper level trough passes by to the north on Monday before digging into the Great Basin and Desert Southwest on Tuesday. Onshore flow will increase with this trough on Monday, with breezy west winds gusting to around 35 mph developing across the mountains and deserts Monday afternoon and evening. The trough along with the development of a coastal eddy will bring a quick return of marine layer low clouds Monday night, which will extend into the western valleys by Tuesday morning. Weak northerly offshore flow develops Tuesday morning, though flow remains onshore to the east. Overall Monday will be a little cooler for most areas except the low deserts, followed by cooler weather in the deserts with little change elsewhere on Tuesday. Weak upper level ridging and light winds will result in slight warming across the area on Wednesday. Another upper level short wave trough may pass by to the north late Wednesday, with another possible later in the week. Despite both the deterministic GFS (Global Forecast System) and EC have this wave somewhere in the vicinity, only 54% of the ensemble space shows some sort of trough and onshore flow, while the remaining 46% indicate upper level ridging over Southern California and weak offshore flow. Neither scenario will result in impactful weather, it's just a matter of whether temperatures will be slightly below or slightly above normal and how much (if any) marine layer low cloud coverage there will be. Marine Elevated seas of 7-10 feet in the outer waters and 5-7 feet in the inner waters will gradually diminish today. The Small Craft Advisory remains in effect through 4am this morning. No additional hazardous marine conditions are anticipated Saturday through Wednesday. Beaches The long period westerly swell bringing elevated to high surf has peaked and will slowly diminish through late this evening. Surf of 4 to 6 feet remains possible for Orange County beaches while 5 to 8 feet wave and sets to 9 feet linger for San Diego County beaches. There is a high rip current risk and hazardous swimming conditions. A High Surf Advisory is in effect and contains more details. Surf trends lower into early next week. Skywarn Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions. NOAA San Diego CA Office: Watches - Warnings - Advisories CA...High Surf Advisory until 4am PST early this morning for Orange County Coastal Areas. PZ...Small Craft Advisory until 4am PST early this morning for Coastal Waters from San Mateo Point to the Mexican Border and out to 30 nm-Waters from San Mateo Point to the Mexican Border Extending 30 to 60 nm out including San Clemente Island. |
