Weather Underground Forecast for Monday, November 09, 2009.

Wet weather will persist over the Western Pacific as another tropical system develops on Monday. Tropical Storm Twentyfive will spin northeast of the Marina Islands and is not expected to make landfall. This system will however, kick up active weather with strong winds and periods of heavy rainfall. Meanwhile, to the north, unsettled weather will return to China as a trough of low pressure pushes in from Mongolia and shoves the dominating high pressure system eastward. This will allow for widespread scattered showers over most of China. Beijing will see scattered clouds and cooler conditions with highs only reaching into the mid-40s(F)/ near 6(C), while Hong Kong will see light and scattered showers as southerly flow pulls ample moisture in from the South China Sea. Expect Southern China to see highs in the mid-80s(F)/ mid-20s(C), with periods of scattered showers.

In the east, a strong trough will continue tracking eastward from eastern China and into the Korean Peninsula. This will allow for lingering clouds over eastern China, while rainy conditions increase over the Koreas and western Japan. Shanghai will see highs in the mid-70s(F)/ lower 20s(C) with overcast skies, while Seoul and Tokyo will see patchy clouds as highs remain in the mid-60s(F)/ upper teens(C).

In Australia, high pressure will hover over the Great Australian Bight as a trough of low pressure tries to build in over Western Australia. Thus, dry conditions are anticipated over the east, while the west may see scattered showers and thunderstorms throughout the day. Expect plenty of sunshine in Sydney with highs in the upper 70s(F)/ lower 20s(C).
