NWS San Diego, CA wrote its last area forecast discussion before the first event at May 19, 8:13 PM PST, 47 minutes earlier.
Area Forecast Discussion National Weather Service San Diego CA 913 PM PDT Thu May 19 2022 .SYNOPSIS... Coastal low clouds will continue each night and morning at the coast and in portions of the valleys. Clouds will clear from most areas late morning each day, but will likely stick around the beaches into the afternoon at times. Onshore winds will increase over the mountains and deserts this afternoon into Friday, with peak gusts to 45 mph. Drizzle is possible west of the mountains Friday morning and again Saturday morning. Little to no accumulation is expected at this time. A gradual warm-up is in store for much of next week, with high temperatures 5 to 10 degrees above average. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES... Evening Update: No changes were needed this evening. A deep marine layer continues and coastal low clouds have already spread into the valleys. Some drizzle is likely late tonight and Friday morning as well due to the deep marine layer, mainly along the mesas and foothills. Onshore winds will continue to pick up overnight and into the day Friday, with gusts around 30 mph possible west of the mountains, and around 50 mph through the mountain passes and along the desert slopes. Previous Discussion (issued at 133 PM): Quite a "May Gray" day at the coast today, with little to no clearing expected. Low clouds will move back inland this evening, extending all the way to the coastal mountain slopes overnight. A longwave trough extending from the Pacific Northwest to the northern Rockies will continue to influence our weather pattern over the next few days, strengthening onshore flow and deepening the marine layer. Stronger southwest to west winds are expected over the mountains and deserts later this afternoon into Friday, with peak gusts topping out around 45 mph. Some local gusts to 50-55 mph can't be ruled out through and below the San Gorgonio Pass. The strengthening onshore flow, combined with the persistent coastal eddy will continue to bring us marine layer clouds and fog each night and morning for the coast and valleys. The marine layer will deepen up a bit tonight into Friday morning, and it could potentially be deep enough to squeeze out some drizzle early Friday morning. The most likely location that would see any accumulating precipitation would be along the coastal mountain slopes. Elsewhere, little to no accumulation is expected. Drizzle is also possible again early Saturday morning. Cooler temperatures are in store Friday for all areas, with high temperatures about 5 to 10 degrees cooler than average over and west of the mountains. Temperatures will be near average in the deserts Friday. Similar temperatures are forecast for Saturday and Sunday as longwave troughing remains over Southern California. As the trough begins to push east early next week, a ridge will slowly build into the southwest behind it, bringing a very slow warming trend to the region. Temperatures will start to increase on Monday, with further warming expected Tuesday through Thursday. Ensembles currently show the warmest day on Wednesday, with high temperatures in the lower deserts exceeding 105 degrees, and widespread 90s for the Inland Empire and Mojave desert. Ensembles and cluster analysis are in pretty decent agreement that this pattern will continue to stick around through much of next week. && .AVIATION... 200340Z...Coast/valleys...Low clouds are occurring up to 35 SM inland this evening, with bases 1300-1700 FT MSL. Patchy drizzle with VIS 3-5SM possible after 06z Fri. Scatter out 16-18z Fri across inland areas, and partial coastal clearing 18-20z Fri, with low clouds persisting into Fri afternoon.
