NWS San Diego, CA wrote its last area forecast discussion before the first event at Jul 28, 7:33 PM PST, 4 hours 27 minutes earlier.
Area Forecast Discussion National Weather Service San Diego CA 833 PM PDT Sun Jul 28 2024 .SYNOPSIS... A trough of low pressure over most of the West Coast will bring fair and cooler weather, along with breezy west winds in the mountains and deserts through Tuesday. A warming trend begins Wednesday and continues through the weekend. Monsoon moisture returns for Friday through the weekend with a chance of thunderstorms over portions of the mountains and deserts each afternoon. Occasional low clouds and fog will continue near the coast, mainly during the nights and mornings. && .DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE... SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES... .Evening Update... Breezy west winds will continue through the mountain passes through this evening, diminishing overnight. Winds are peaking at this hour with gusts near 35-50 MPH near the San Gorgonio Pass and 25-35 MPH elsewhere. Low clouds off the coast this evening will slowly cover southern areas of the coast, with a lesser chance into parts of Orange County. The temperature forecast remains on track to bring near to slightly below average temperatures through the next couple of days thanks to a weak trough to our north. Model ensemble clusters depict a ridge expanding over the southern Rockies and Southwest, leading to warmer weather with increasing monsoonal moisture and humidity. ECMWF/GEFS probabilities for PWAT values over 1 inch increase by late in the week for mountains and deserts. This combined with subtle increases in instability will lead to chances for daily showers and storms across the higher terrain. Chances could increase by the weekend into next week for deserts and adjacent valleys as well, but confidence on this factor remains low at this time. .Previous Discussion (135 PM Sunday)... Our break from oppressive summer heat will continue through Tuesday, with max temperatures a few degrees below normal across the region. For that we can thank a weak upper trough over the Northwest that has sagged southward. The marine layer will persist as is, with similar cloud levels and cloud/fog coverage, and timing relegated to very late nights and early mornings. The onshore flow that strengthened yesterday will continue through Tuesday to produce strong and gusty westerly winds through parts of the mountains and deserts during the afternoons and nights through Tuesday night. Strongest wind gusts should peak through the San Gorgonio pass at around 45-50 mph. The cooler period will end; the upper ridge now over Texas will oscillate back into the interior West, eventually over the Great Basin, where it seems to have found a happy summer home. That should reduce our marine layer and coastal cloud cover. It will also warm up all areas, especially inland. With the ridge axis north of our latitude, the flow underneath will become southeast, opening the door for monsoon moisture to return to SoCal. A weak inverted trough is featured by most guidance to move up from Baja and rotate through SoCal Thursday and Friday, a feature surprisingly consistent among runs of model guidance. We'll continue to watch for an elevated convection episode, producing showers and thunderstorms anywhere in SoCal. But for now, that inverted trough doesn't look sufficiently moist and unstable for that. Right now we've got slight chances of afternoon showers and thunderstorms in the mountains and high desert starting Friday. The moisture increases next weekend for greater chances, basically in the mountains during the afternoons...at least for now. The warming trend will boost inland max temps a little above average starting Wednesday, then up to about 5-10 degrees above average by Saturday. That means around 115 in the low desert and around 105 in the Inland Empire and High Desert. Right on schedule for the dog days of summer. && .AVIATION... 280300Z...Coast/Valleys...Low clouds will be slow to develop tonight with local BKN stratus near the beaches 04Z-07Z Mon becoming areas of BKN/OVC CIGs 07Z-17Z Mon. Similar bases to last night expected, 600-1100 ft MSL and tops to 1200 ft MSL within 10-20 miles of the coast. Timing of CIGs at coastal airports is low confidence, especially at KSNA where low clouds again may not occur at all through Mon morning. Areas of VIS 0-3 miles in BR/FG will occur over higher coastal terrain, including the coastal mesas of San Diego County, 09Z-16Z Mon with higher terrain locally obscured. Low clouds scattering out of coastal sites 15-17Z Mon, remaining offshore through late Mon evening. Mountains/Deserts...Clear skies with unrestricted VIS will prevail through Mon evening. && .MARINE... No hazardous marine conditions are expected through Friday. && .SKYWARN... Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions. && .SGX WATCHES/WARNINGS/ADVISORIES... CA...None. PZ...None. && PUBLIC...APR/MM AVIATION/MARINE...CSP
