Light rain is expected Wednesday morning, with more significant rainfall hitting the county this weekend.

National Weather Service meteorologist Daniel Harty said the forecast calls for about a tenth of an inch falling in the Bakersfield area beginning Wednesday morning. There's a little break after that, with another storm system arriving Friday.

"It could be a wet weekend," Harty said Monday.

The system will be a warm one -- lows Wednesday are forecast in the 50s -- so motorists won't have to worry about icy conditions, even in the mountains, Harty said. There will, however, be low-visibility conditions because of the rain and clouds.

It was too early to forecast how much rain Bakersfield could receive this weekend. He said there were no estimates yet because so much can change in just a few days.

But he did add that it's possible some areas of the county could receive as much as a quarter of an inch of rainfall over the weekend.

The Weather Channel website is reporting "a deep dip, or trough, in the jet stream will carve out over the eastern Pacific Ocean," resulting in storm systems impacting the West Coast through this weekend. Wednesday's weather is described as "routine," but for the weekend the storm system will "tap into an atmospheric river of moisture extending from just north and west of Hawaii to the West Coast."

The result will be that some areas, "particularly in the coastal ranges of northwest California, could pick up more than 10 inches of total rainfall through this weekend, leading to flash flooding and river flooding," according to the website.
