Area Forecast Discussion National Weather Service San Diego CA 204pm PDT Monday Mar 18 2024 Synopsis Showers and thunderstorms are expected this afternoon and evening. Thunderstorms are most likely in the valley and mountains but there is a potential they could drift far enough west to impact coastal areas. Slight chances of showers and isolated thunderstorms continue into Tuesday but become more confined to the mountains and foothills. Dry conditions are expected by Wednesday. Near to slightly above normal temperatures are expected through Friday, with a cooling trend into the weekend. Night and morning low clouds and fog are expected along the coast for the middle to end of the work week, with cloud coverage becoming more widespread into the weekend. Breezier conditions over the mountains and deserts expected this weekend, with the potential for precipitation. For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties At 1 PM, the energy from the low pressure system currently over eastern California had reached our forecast area. This has made for an active afternoon with numerous showers and a few thunderstorms in the mountains, valleys, and locally in the deserts. Storm movement continues to be south and west, with showers and thunderstorms expected to impact coastal areas through this evening. The main impacts from thunderstorms will be gusty winds and small hail. Winds at 850 and 700 mb are expected to stay between 10-20 kt for the most part, which will keep the storms moving and limit the flooding potential. Areas of slick roads expected during the evening commute. Showers and thunderstorms across the area are expected to diminish into this evening. In addition to rain at lower elevations, periods of snow are expected in the mountains above 7000 ft through Tuesday. Up to an inch of snow is expected above 7000 ft. There is good agreement that the low will push back to the east by Tuesday, keeping the threat of any showers or thunderstorms more confined the the mountains and mountain foothills. By Wednesday the low should continue it's journey east, allowing a weak ridge of high pressure to build over central California. This will allow temperatures for the middle to end of the work week to remain near to slightly above average for this time of year. Marine layer night and morning low clouds and fog are expected to return to the coast by Wednesday and cloud coverage will spread further inland into the end of the week as onshore flow increases. A low pressure system is expected to move south and east from the Gulf of Alaska into the US West Coast this weekend. Ensemble solutions are in good agreement the incoming trough will begin to influence our weather on Saturday. This means cooler, cloudier, and potentially wetter conditions can be expected for the weekend into early next week. An increase in westerly winds can also be expected for at least the mountains and deserts. There is still some uncertainty with the timing and placement of the trough between the global models. Where the low goes will impact how much precipitation Southern California will get and when. Current forecast for the upcoming weekend closely follows NBM with periods of slight chances of precipitation starting on Saturday and continuing into Monday. Marine Showers and thunderstorms over the coastal waters late this afternoon and evening, most likely near shore. Any thunderstorm could produce gusty, erratic winds and lightning. Otherwise, no hazardous marine weather is expected through Friday. A Marine Weather Statement has been issued for lightning over the coastal waters through 8pm tonight. Beaches Scattered thunderstorms dropping lightning late this afternoon and evening. Skywarn Skywarn activation is requested. NOAA San Diego CA Office: Watches - Warnings - Advisories CA...None.
