Los Angeles, CA – Southern California residents face a significant change in weather this week, with downtown Los Angeles forecast to reach 83 degrees Monday before rain chances climb to 90% Wednesday night. The shift comes ahead of NOAA's Oct. 26–Nov. 1 outlook, which favors above normal precipitation across much of California as November begins, although the temperature outlook is less decisive across the Los Angeles region than farther north.
According to NOAA's Climate Prediction Center, the eight to 14 day temperature and precipitation outlooks issued Sunday, Oct. 18, favor above normal precipitation across much of California during Oct. 26–Nov. 1. The temperature outlook places the Los Angeles area near a transition between below normal temperatures favored farther north and near normal conditions across portions of Southern California.
Los Angeles faces 90% rain chance Wednesday night The National Weather Service forecast for East Los Angeles shows Monday reaching approximately 83 degrees under sunny skies.
Tuesday remains warm, with mostly sunny conditions and a high near 77 degrees.
By Wednesday, the forecast changes considerably. Showers become likely, mainly after 11 a.m., with mostly cloudy skies and a high near 73 degrees. The chance of precipitation reaches 60%.
Rain chances increase further Wednesday night, when showers and a possible thunderstorm are forecast. The precipitation probability reaches 90%, the highest shown in the supplied forecast.
Thursday brings another chance of showers, with partly sunny skies and a high near 69 degrees.
That represents a 14 degree decline in daytime temperatures between Monday and Thursday.
Conditions improve Friday, when sunshine returns and temperatures climb to approximately 73 degrees.
Saturday and Sunday are forecast to be sunny, with highs near 78 degrees both days.
The supplied forecast does not establish rainfall totals, flooding or severe thunderstorm warnings. Residents should monitor updates as the midweek precipitation approaches.
Southern California's November outlook differs from the north NOAA's extended temperature map shows a pronounced cooler than normal signal across much of Northern and Central California.
Farther south, including the Los Angeles metropolitan area, the temperature outlook becomes less decisive as the region approaches the boundary between below normal and near normal conditions.
That distinction matters because the stronger cooling pattern favored across the Pacific Northwest does not extend uniformly into Southern California.
The precipitation outlook, however, favors above normal totals across much of California, including the Los Angeles region.
For Los Angeles County and nearby Orange and Ventura counties, the outlook indicates an increased likelihood of wetter than usual conditions during Oct. 26–Nov. 1.
However, NOAA's maps do not establish specific rainfall amounts or determine which individual days will be wet.
What the November transition means for Los Angeles For Los Angeles residents, the immediate weather story is the sharp contrast between Monday's 83 degree warmth and the wetter, cooler conditions forecast Wednesday and Thursday.
The change could affect outdoor plans and commuting conditions, particularly Wednesday night when rain chances are highest.
Separately, the National Weather Service Weather Prediction Center's Oct. 19 discussion highlights showers and thunderstorms spreading into portions of central and southern California Tuesday. That earlier development is distinct from NOAA's extended outlook.
The longer range precipitation outlook suggests additional wet weather potential as November begins, but it does not establish that this week's rain system will continue into the following week.
Updated National Weather Service forecasts will help determine whether the wetter tendency translates into measurable rainfall across the Los Angeles Basin and surrounding communities.
Are you ready for Southern California's return to fall rain, or would you rather keep the sunshine and 80 degree afternoons?
