The storms have passed and California’s dry winter has returned, raising the specter that the state could be entering another drought less than a year after the last one officially ended. After a brief spell of rain and snow improved California’s water conditions last week, the National Weather Service said Monday it’s forecasting at least two weeks of dry weather. A strong high-pressure ridge has settled over the Pacific Ocean. The ridge will block any storms from reaching the state, and “is going to stick around for a while,” said Michelle Mead, a weather service meteorologist in Sacramento.
