Weather Summary For Asia & USA

Weather Underground Forecast for Friday, October 14, 2011.

Tropical Depression Banyan will continue trekking away from the Philippines on Friday. A deep trough of low pressure will dig into southeastern China and allow Banyan to veer northwestward throughout the day. As this system progresses, slow intensification is anticipated as it moves into more favorable conditions of the the South China Sea. Banyan should reach tropical storm strength by early Saturday morning with maximum sustained winds near 40 mph and higher gusts. This system is expected to veer westward toward Vietnam on Sunday. For more information on Banyan.

Outside the tropics, a cold front will bring more active weather to southern Japan as it advances toward the Ryukyu Islands, Kyushu, Shikoku and southern Honshu. A wave of low pressure along the northern end of this front will enhance precipitation in southern Honshu and spark scattered thunderstorms as well. Only a slight dip in temperatures are expected with the passing of this system during the weekend. 

In China, low pressure may kick up a few spotty showers in the northeastern provinces of the nation, while showers along the southeastern coast ease away throughout the day. 

For Australia, a trough of low pressure will move into Queensland and New South Wales with showers and chances of thunderstorms. Active weather will continue along these coastal areas through the weekend. Meanwhile, hot weather will continue in the northern tier of the nation as a warmer airmass settles over the region. Temperatures are expected to reach into the lower 100s(F)/near 40(C) through much of the weekend.


The Eastern US will remain wet on Friday as a trough of low pressure strengthens over the Great Lakes. Flow around this system will continue pushing a cold front eastward, starting the day over the Appalachians and moving offshore by evening. The northern edge of this front will linger over the Northeast and continue triggering widespread scattered showers throughout the day. At the same time, the back side of this system will continue to push a few disturbances through the Great Lakes. Thus, the storms in the Southeast will taper off by evening, but persist for the Great Lakes, Midwest, and Northeast. Rainfall totals will range from 0.5 to 1 inch across the Northeast. 

Behind this system, a ridge of high pressure will remain the dominant weather feature for the West Coast, Rocky Mountains, and Plains. The leading edge of this system will create some strong winds for the Northern Plains and Upper Midwest, due to the change from low to high pressure. Expect winds to vary around 20 mph, with gusts between 30 and 35 mph. A gradual warming trend will accompany this system. 

In the Northwest, a weak trough of low pressure moves eastward over the Northern Rockies from the Pacific Northwest. Expect scattered rain showers with snow showers at the highest peaks.
