October storm may bring first wet Halloween to Los Angeles since 2014
Conflicting weather models create uncertainty over the precise arrival of the rain, but forecasters confirm precipitation is expected during the holiday weekend.

An October storm system is moving toward Southern California, posing a threat to outdoor Halloween events and potentially marking the first rainy holiday in Los Angeles since 2014. The weather pattern could shift the region's typical dry autumn conditions, bringing clouds and precipitation to the Southland this weekend.
NBC4 Meteorologist Shanna Mendiola stated that the timing of the rain remains uncertain because major forecasting models offer conflicting schedules. The European Model, or ECMWF, predicts light showers on Friday, with the primary band of rain arriving Saturday night and continuing into Sunday. In contrast, the American Model, or GFS, projects that the rain will not arrive until Sunday.
Mendiola explained that the two systems often converge in their predictions as the storm approaches. "As we get closer, they kind of start to agree with another and then we can get a better idea of when exactly this is happening," she said. She confirmed that residents should expect some rain during the weekend regardless of the specific day it begins.
The weather shift follows a period of clear skies and rising tides. "After we say goodbye to the tides, we say hello to all the clouds and the elements coming from the sky," Mendiola noted. She added that a chance of showers exists on Friday, leading into the wetter conditions expected for Halloween.
Temperatures are set to drop across the Southland throughout the weekend. The cooling trend aligns with the arrival of the storm system, which may dampen plans for outdoor trick-or-treating and related community activities.
