A weak area of convection in the tropics continues to move over the Southern Philippines today bringing heavy precipitation to much of Mindinao. This same distrubance can be seen extening acorss Malaysia and Singapore. Over 60mm of rainfall in the past 24hrs has been reported in numerous locations along this belt. The analysis above shows the series of low pressures in this belt.  Expect these rain showers to continue to linger in this belt through the rest of the week and even pickup by Thursday in to Friday. North of this instability though Northern Luzon will see fair weather with afternoon airmass thunderstorms being the main concern in cities like Manila and Bangkok.

Japan Snowfall 3 day Outlook

As we look at the westerlies a low pressure area is pushing off of Eastern China today bringing the threat of rain showers to Hong Kong through the Ryuku islands. This is expected to push through on Tuesday before moving on to the main island of Honshu where Tokyo will see rain showers by Wednesday evening.

Behind this low more snow is going to fall along North West Japan.   While the cold air continues to filter South across the Sea of Japan on Tuesday in to Wednesday expect over 50mm of snowfall to occur in Eastern Hokkaido through Central Honshu. This will relax for a brief period of time on Thursday prior to the next low that is expected to strike the area.

Keep Checking Back for more updates.

A weak disturbance hits the Southern Philippines with a break in the wet weather to the North. 27 FEB 2012

A break in the wet weather is occurring over most of Japan and Korea today for a brief period of time as a bubble area of high pressure sets in in between a fast moving low running away from Honshu today and another low setting up across the Tibetan Plateau and starts to push East bringing yet another shot of heavy rainfall by mid-week to North East Asia. The exception for the break in the unpleasant  weather yet again is the west coast of Japan where show showers from the ocean effect snow machine continue to drop the white stuff across the region. The image to the right displays yet again over 50mm being expected across parts of North East Honshu.  To the east though Sunday’s cloud cover will give way to sunnier skies across Tokyo with highs reaching near 10degrees on monday.  North of the Polar Front jet (the main desperate of the cold and warm air ) temperatures continue to dip below freezing.

Towards the south the tropics remain warm and pleasant going in to Monday.  There is a weak disturbance approaching Mindanao that could tally up numbers above 50mm in localized areas along the eastern portions of the island Monday, yet this is expected to remain weak and only last through Monday with the weather clearing by mid-week.

Therefore in summary the tropics remain mostly quite today, another great day to get out and enjoy the outdoors.  An umbrella is going to be a necessary accessory by mid-week in Korea and Japan and bundle up for those of you reading this from Hokkaido and Northern China.

Have a great day everyone! ~Meteorologist Robert Speta

26 FEB 2012 Western Pacific & Eastern Asia Weather Update

Great Beach Day in Palua

The story remains unchanged as we go in to Sunday for the tropics.  This weekend still remains a great beach weather day for the Philippines, Guam and even much of South East Asia as the North East monsoon remains laxed across the region.  Therefore expect clear skies for the most part in the the tropics over the course of the week. A few exceptions still remain, first is the daily afternoon tropical thunderstorms that could produce some heavy rainfall at times.  These likely be accompanied by a few bust of lightning, yet none should be severe and rainfall should remain low as Pat stated in his earlier update.  High temperatures will also remain tropical in nature with them peaking up in to the low 30s from Guam to Thailand.  Once again enjoy this great weather.   Typhoon season 2012 is only just prior to dawn currently, a short lived night for the western pacific.

2012 Typhoon Summary as of FEB 26

If your anywhere from Eastern China to Japan though this week will be 180 degrees in the opposite direction.  Heavy rainfall is expected to fall in most of the region while a series of low pressure areas push across the boundary of low pressure that is set up currently.  Therefore keep your umbrella handy and be sure to dress warm as snow will be expected in northern Japan through Korea as well.  Dense fog is also setting up across much of China including Hong Kong due to the cold air spilling in from the North over the relatively warmer surface of the region.  This is often seasonal and should become more relaxed in the weeks to come.  (On the surface Chart below the dots in Yellow indicate fog with the dots in green indicating rain.)
