Measurable rainfall is expected, especially over Los Angeles county. Light rain or drizzle will affect much of the area tonight through tomorrow night. The best chance of precipitation will be along the southern foothills and the San Gabriel Mountains, where up to 0.50 inch of rainfall will be possible. Otherwise, most areas will receive less than a tenth of an inch.

Unseasonably cold air associated with this system will drop snow levels to between 5,000 to 6,000 feet. Light snowfall will be possible at the higher elevations Wednesday night, with an inch or two of accumulating snow likely above 6,500 feet. Greater amounts will fall above 7,500 feet.

Southwest to south winds ahead of the system will increase over much of the area late tonight and Wednesday. The strongest winds will be focused over the Los Angeles County mountains and Antelope Valley, where wind gusts up to 50 mph will be possible. Apple and Lucerne valleys will experience gusts up to 65 mph, causing reduced visibility due to blowing sand and dust.

The storm will exit Thursday; it’ll be followed by dry and warmer weather Friday through Sunday.
