| Area Forecast Discussion National Weather Service San Diego CA 141pm PDT Tuesday May 30 2023 Synopsis A deeper marine layer will continue into Thursday with night and morning coastal low clouds extending onto the lower coastal slopes of the mountains. Little to no daytime clearing will occur at the coast through the weekend. Showers will occur at times over/west of the mountains through Wednesday morning. Gusty southwest to west winds will occur on the desert mountain slopes, through the passes and into the deserts through Thursday, with the strongest winds this afternoon. High pressure aloft near the West Coast will bring inland warming for the weekend with night and morning coastal low clouds not spreading quite as far inland into the valleys. For early next week, a low pressure system from the west could bring cooling and deepening of the marine layer. For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties At 1 PM, visible satellite shows low clouds continuing to stick around land areas, with some clearing occurring over the waters and some beaches this afternoon. Some brief additional clearing may occur this afternoon, but the clearing will likely not be significant, with most land areas remaining mostly cloudy this afternoon. There has been additional shower activity this morning into this afternoon, mostly along the coast and on the foothills of the Santa Ana Mountains. The highest accumulations have been concentrated in coastal southern Orange County and along the foothills of the Santa Ana Mountains, where up to 0.20" have fallen in the past 6 hours. A weak closed low pressure system, currently situated over Point Conception, will progress eastward over Southern California today and tonight, then rapidly push into Arizona on Wednesday. As the closed low moves over SoCal, additional shower is expected west of the mountains and on the coastal slopes of the mountains. High resolution models indicate shower activity waning this afternoon, then picking up again this evening and overnight. Slight chances for showers have been added to the forecast for all areas west of the mountains and on the coastal slopes through Wednesday morning. Showers will be hit and miss, so some areas might not see any rain at all. The trough will push east of our area Wednesday afternoon, so shower activity should decrease after that with dry northwest flow prevailing. Gusty west winds will occur each afternoon and evening through Thursday over the desert mountain slopes, through the passes, and into the deserts. Strongest winds will be this afternoon and evening, with peak gusts to 50 mph. Through the San Gorgonio pass and into the northern Coachella Valley, wind gusts could reach up to 60 mph. It'll be rather chilly through Wednesday, with high temperatures 5 to 10 degrees below average at the coast and in the deserts, and 10 to 15 degrees below average in the valleys and mountains. Wednesday is expected to be the coolest day of the week for all areas. After Wednesday, temperatures begin to "warm-up" a little for the end of the week as heigheights rise slightly once the closed low passes east. Areas west of the mountains will remain slightly below average through the weekend, but the deserts will warm to 2 to 5 degrees above normal, into the lower to mid 90s for the Mojave and 100 to 105 for the Coachella Valley and San Diego desert. Late this week and this weekend, low clouds that push into the valleys each night and morning should clear the valleys each afternoon, but little to no clearing is expected along the coast. For early next week, there remains decent ensemble spread on the pattern, though it appears the subtropical jet stream will move near Southern California or northern Baja, with a low pressure system moving in from the west. Minimally, this will bring us cooler temperatures and increased onshore flow. Some ensemble members show some measurable precipitation around the next Tuesday/Wednesday time frame, but for now the forecast remains dry. Marine No hazardous marine conditions are expected through Saturday. Beaches Moderate rip current risk and elevated surf today. The highest surf will occur on the south facing beaches where occasional sets to 5 feet are expected. Surf and rip current risk lowers into Wednesday. 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...None. PZ...None. |
