Late-season storms will impact the West this week, bringing much cooler air, rain and mountain snow to California.
The first storm will be rather slow-moving, spreading more rain into the Bay Area of California today.
"This will be a pretty good rainmaker," Ken Clark, AccuWeather.com expert senior meteorologist, said. "A general rainfall in north-central California from the Bay Area to Sacramento will be 0.50-1.00 inch."
Even more rain will fall in the western slopes of the coastal ranges and the Sierra.
While the rain is welcome in California, travel problems are likely to result. Low clouds and rain could delay flights at the San Francisco International Airport, while traffic may be slowed on the ground.
With chilly air arriving, it will be snow that falls in the higher elevations. One to two inches of snow will accumulate at resort level in the Sierra with some disruptions possible along major passes such as Donner Pass.
"Rain will reach the Los Angeles Basin into Wednesday morning with about one third to two thirds of an inch falling," Clark said.
Snow will fall over the mountains of Southern California by midweek with snow levels as low as 4,500 feet. Some snow may even mix in down to pass level, but no accumulation is expected.
The cooler and unsettled weather pattern will last through late-week in the West.
A tropical wave is likely to become the Atlantic Basin's next tropical storm as it approaches or crosses the Caribbean Sea later this week and potentially pose eventual threats to North America.
Fall air has finally arrived in the northeastern United States and may yield the first frost of the season in parts of the region to end this weekend.
Typhoon Megi will continue to strengthen before threatening lives and property across Taiwan and eastern China this week.
Jose Fernandez, pitcher for the Miami Marlins, died in a boating accident in southern Florida early Sunday morning.

Wintry weather marked the first days of autumn across parts of the Mountain West as snow mixed in with the changing fall foliage.
