The National Weather Service in San Diego forecasts a warm-up into Wednesday, followed by potential showers late Thursday into Saturday as the remnants of Hurricane Priscilla head toward southwestern California. According to an early morning update from the National Weather Service, the increasing high pressure to the southeast is responsible for the climbing temperatures, which, despite the warmth, will still be a few degrees below average for coastal areas and a few degrees above for the mountains and high desert.
For inland dwellers looking forward to the marine layer's chill, expect that lowering clouds will not spread as far into the valleys by Wednesday. Although a mix of temperatures ranging from the 70s near the coast to the 90s in the lower deserts is on the horizon, by the weekend, "high temperatures for inland areas next Sunday as much as 5 to 10 degrees below average" are anticipated, as stated by the NWS San Diego in their latest report.
Attention then turns towards the anticipated moisture from the remnants of Hurricane Priscilla, with chances for showers peaking on Friday. Meteorologists at NWS San Diego suggest that the model cluster hinting at the wettest forecast for Southern California contains more than half of the ECMWF ensemble members, indicating a greater likelihood of significant rainfall.
The impending showers could come as both a surprise and reprieve, as the typical sunny skies of Southern California give way to "chances for measurable rainfall peak on Friday at 25 to 35 percent" and maybe even "one inch or more of rainfall in the mountains around 5 percent." Residents near the coasts and valleys are advised to prepare for low clouds with bases near 1500-2000 feet MSL, while inland valleys, mountains, and deserts are expected to maintain mostly clear and VFR conditions through this period, per the NWS San Diego.
No hazardous marine conditions are currently on the cards through Friday, which should be music to the ears of seafarers. But watch out for that "slight chance of thunderstorms near the coast on Friday afternoon," as the NWS San Diego warns. Local weather spotters, while not being called into action, are reminded to report substantial weather conditions should they occur.
