| Area Forecast Discussion ...CORRECTED National Weather Service San Diego CA 950pm PST Sunday Dec 3 2023 Synopsis A warming trend continues through the first half of the week. The nigheights will stay quite cool though, especially in wind-sheltered valleys. Locally gusty offshore winds will occur each night and morning along the coastal mountain slopes. Cooler with onshore flow and a brief rebuilding of the marine layer for later in the work-week. Warmer again for next weekend with offshore winds. For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties This evening, high clouds continue to move across the region from the northwest. Today's high temperatures were a few degrees warmer than yesterday and were generally a few degrees above seasonal averages. Mostly light offshore breezes in several areas from the foothills to the coast. Expect low temps tonight similar to last night. From previous discussion... A building ridge of high pressure continues to move eastward over the western United States. The high pressure and offshore flow will continue the warming trend through Tuesday, which will likely be the warmest day of the week. Highs will run 8-13 degrees above seasonal averages, reaching the upper 70s to low 80s across coastal areas away from the immediate beaches, the valleys and the lower deserts, and the 50s and 60s in the mountains and High Desert. Periods of locally gusty Santa Ana winds will occur Monday morning and again Tuesday morning, but will generally remain confined to the coastal mountain slopes and wind-prone passes. This will dry the air mass slightly, so overnight low temperatures could fall quickly each evening in wind-sheltered areas, more so if we lose our high cloud cover. A progressive trough will move inland across the Pacific Northwest by the second half of the week, leading to the return of onshore flow, cooler temperatures and gusty winds in the mountains and deserts. This system is expected to pass well to our north and east and will lower our high temperatures to near seasonal averages on Thursday and Friday. By next weekend, overall ensemble guidance supports another ridge dominating the pattern across the western U.S. Differences still exist in the placement and strength of the ridge, with European model solutions showing a more amplified and mature ridge, while the GFS favors the slower building of heights. This will impact the degree of warming and the potential strength of offshore winds next weekend. Looking at the long-range pattern, ensemble guidance favors mostly dry conditions through the next 10 or so days. The pattern looks to change by mid-month, perhaps bringing the storm track a bit farther south. Marine No hazardous marine weather is expected through Thursday. 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.
