While Turlock has been doused with showers this week, skies are expected to clear just in time for the weekend before a possible return to rainy weather Thursday, according to the National Weather Service. The heavy rainfall accumulated over the past several days will result in high river levels and stream flows even after rainfall tapers off early Saturday. As a result, forecasters issued a flood warning until 9:15 a.m. Saturday for several counties in the interior of northern California, including Stanislaus County.
