Area Forecast Discussion National Weather Service San Diego CA 132 PM PDT Mon Jun 16 2025
SYNOPSIS
Hot conditions will continue through Wednesday for inland locations.
Gradual cooling expected Thursday into the weekend. Patchy night and morning low clouds and fog, that is locally dense, are expected tonight into Tuesday along the coast. The marine layer will gradually increase in depth Wednesday through the weekend, with low clouds becoming more widespread and making it into the valleys.
Breezy west winds across the mountains and deserts each afternoon and evening, strongest today.
DISCUSSION
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES...
Hot conditions will continue for inland areas through Wednesday with widespread moderate HeatRisk in the inland valleys, mountain foothills, and deserts. This afternoon, moderate to locally major HeatRisk will occur in the low desert. Make sure you're staying hydrated and seeking shade if you're spending time outdoors through the middle of the week. If possible, avoid strenuous outdoor activity during the hottest part of the day (through 5pm). Most model guidance is showing minimal changes in high temperatures between today and Tuesday for inland Orange County, San Diego valleys, and mountains. For inland Orange County and western portions of the San Diego valleys, how much marine layer low cloud coverage develops overnight will have an impact on how hot it gets Tuesday. Currently high resolution guidance keeps low cloud and fog coverage quite patchy overnight, so the forecast is trending towards the hotter end of the guidance. Patchy dense fog is possible, most likely in San Diego county near the coastal mesas. For the Inland Empire, temperatures will see minimal changes through Wednesday, keeping highs between in the upper 90s to just over 100 degrees.
A very gradual cooling is expected in the deserts for Tuesday into the weekend, although highs will remain 5 to 7 degrees above average. The exception is the High Deserts are expected to see a degree or two of warming on Wednesday, before continuing their cooling trend. Widespread moderate HeatRisk will continue through Thursday for the High Desert and Friday for the low desert.
A passing weak area of low pressure will move across central California today, which will strengthen the onshore pressure gradient. That will bring breezy west winds to the desert mountain slopes, below the passes, and into the deserts during the afternoons and evenings. Strongest winds are expected this afternoon and evening with gusts 30 to 45 mph, locally up to 50 mph through the San Gorgonio Pass.
Ensemble guidance is in good agreement that the ridge of high pressure will get pushed east ahead of an incoming low pressure system approaching the Pacific Northwest. The incoming low will bring widespread cooling, a deeper marine layer, and increased winds over the mountains into the deserts. Marine layer low clouds and fog are expected to reach well into the valleys by the end of the week.
There is high confidence in dry conditions with this passing trough.
Near average temperatures will return by Friday, with below average temperatures expected through the weekend.
AVIATION
162030Z
Coast/Valleys
Mostly clear and VFR through the evening.
Areas of low clouds will redevelop and push ashore after 04Z, but only into westernmost valleys overnight and without uniform coverage. Bases will be around 400-600 feet MSL with widespread vis 2-5SM, but near zero over higher coastal terrain and western valleys. Scatter out Tuesday 15-16Z.
Mountains/Deserts
Clear skies and unrestricted vis through Tuesday. West winds through 08Z with gusts 20-30 kts, locally near 40 kts through the San Gorgonio Pass, leading to MOD UDDFS.
MARINE
Wind gusts around 20 kts in the outer waters this afternoon and evening near San Clemente Island. Otherwise, no hazardous marine conditions are expected through Saturday.
SKYWARN
Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.
SGX WATCHES/WARNINGS/ADVISORIES
