Area Forecast Discussion National Weather Service San Diego CA 123 PM PDT Fri Sep 18 2020

SYNOPSIS. After yet another warm day today, slow cooling will begin to spread into the region as a trough dances inland to our north this weekend. The cooling will continue through Monday and Tuesday with warming for next Wednesday and Thursday. Night and morning coastal/valley low clouds and patchy fog will gradually return and spread into the western valleys for Sunday through Tuesday mornings.

DISCUSSION. FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE . SAN DIEGO . WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES .

SHORT TERM. (Today through Sunday) . As winds start to blow later this afternoon and evening, areas of the high desert and San Bernardino Mountains will see periods of haze and smoke from the El Dorado and Bobcat fires. Otherwise, looking like a fairly clearer for the rest of the day elsewhere. As a trough pushes inland across Northern California and Oregon this weekend, greater onshore flow will bring cooling with readings closer to average by Sunday. Nudged up temperatures just a bit for this weekend, though still a lot cooler than we've been seeing!

Gusty winds are already starting to get going as we are seeing some gusts near 25 MPH at this hour with the onshore push. Winds will be from west and southwest sustained between 15-25 MPH, though areas of the High Desert and San Bernardino Mountains may gust to 35-40 MPH through early tonight. Winds will lighten up a bit into the weekend, though these areas still may see some local gusts 30-35 MPH on Saturday. As we settle into this troughing pattern, we will see low clouds and patchy fog each night and morning through the weekend.

LONG TERM. (Monday through Thursday) . Many areas will be at or a bit below average for Monday and Tuesday as neutral flow takes hold after the trough passage to our north. A large trough from the Gulf of Alaska will push into the Pacific Northwest by the middle to latter part of next week as a ridge to our southwest begins to expand and build into our region. Ensembles continue to depict the ridge winning out and making a large presence over the Desert Southwest. This will bring us some warmer weather and a shallower marine layer as we get into Wednesday and Thursday, though the should be a bit short lived as the ridge slowly progresses east later next week.

AVIATION. 181945Z . SCT thin high clouds AOA 15,000 feet through tonight. Some FU in vcnty of fires with vis reduced to 1-3 SM very locally. Patchy coastal low clouds and fog possible after 08Z tonight into Saturday morning. The risk of BKN-OVC low cloud development at KSAN tonight still looks to be quite low, so moderate-high confidence in no BKN- OVC low clouds at KSAN tonight into Saturday morning.

MARINE. No hazardous marine conditions are expected through Tuesday.

FIRE WEATHER. It will remain very dry for inland areas through the evening with the humidity falling to around 10 percent this afternoon for the mountains, deserts, and inland valleys. Stronger and gusty southwest to west winds from the desert slopes of the mountains into the adjacent desert areas will continue this afternoon into the evening. The stronger and more widespread winds are expected along the desert slopes of the mountains in San Bernardino County into adjacent desert areas with gusts 35-40 mph this afternoon and early evening. The combination of low humidity and stronger winds will bring a few hours of near critical fire weather conditions during the mid and late afternoon for the desert slopes of the San Bernardino Mountains into the adjacent desert areas. Humidity is expected to recover with weaker winds progressively each day into the weekend and early next week.
