Weak weather features will bring a few scattered showers to parts of Asia on Saturday. A ridge of high pressure creates a blocking pattern as it sits over the Yellow and East China Seas, stretching westward into northern China and eastward over the Korean Peninsula. This will create another dry and sunny day for most of northern Asia. Expect Beijing to see plenty of sunshine with highs near 40(F)/ 4(C), while Seoul will also be sunny but slightly cooler with highs in the lower 30s(F)/ near 1(C). Meanwhile, multiple troughs of low pressure will move around this system to the south and east. One trough of low pressure will move over southern China, pulling moist air in from the South China Sea. Expect light and widespread rain showers to develop from northern Vietnam through Shanghai.
