Major winter storm expected on Thanksgiving Day

SAN DIEGO (CNS) - A major winter storm is expected to hit the Southern California area Wednesday through Friday, the National Weather Service said.

"Though exact timing remains uncertain, confidence is high that widespread rain, heavy at times, will affect the region for the holidays,'' the NWS said.

-- Sunday: Warmest day, with mild temperatures and mostly clear skies;

-- Monday: Slightly cooler temperatures, with an increase in clouds in the evening;

-- Tuesday: Continued cooling. Surf beginning to increase, with heavy evening winds is mountains and deserts. Possible showers late;

-- Wednesday: Major winter storm arrives. Good chance of rain, with possible mountain snow.

-- Thanksgiving: Potential brunt of winter storm. Widespread and persistent moderate to heavy rain likely. Heavy snow likely in mountain communities. Treacherous travel conditions expected, with flooding possible. Much cooler.
