Weather Underground Forecast for Saturday, November 21, 2009.

Tropical storm activity is not expected over the Western Pacific on Saturday, however, much of Asia will see areas of wet and unsettled weather. A low pressure system lingering over the Sea of Japan will continue pushing moist flow over northern Japan triggering light and scattered showers. Tokyo will only see a few scattered clouds with highs in the upper 50s(F)/ mid-teens(C).

Meanwhile, a wide ridge of high pressure will build over China and the East China Sea and stretch over the Korean Peninsula. This will bring sunny and warm conditions with cool and clear overnight conditions. Seoul and Beijing will see mostly sunny skies with highs in the upper 30s(F)/ near 3(C). Flow around this system will create a front that will stretch from western Japan and into southeastern China. Expect overcast skies over Shanghai with highs near 50(F)/ 10(C), while Hong Kong will only see a few patchy clouds with highs in the mid-60s(F)/ upper teens(C). This front will also create onshore flow over Vientam and Cambodia, allowing for scattered showers to persist over Indochina.

In Australia, a low pressure system will move into the Great Australian Bight and spread over the surrounding shores. Thus scattered showers and thunderstorms will develop over Western and South Australia. Higher pressure dominating in the north will allow for another dry and sunny day. Sydney will see increasingly cloudy skies with highs near 90(F)/ 32(C).
