Daily update- Thursday, March 10, 2016

NWPAC outlook, 10 MAR

Much cooler air has plunged into the north and central regions, bringing a taste of winter back to the day. The south region is once again dangerously hot as the tropics stay mostly quiet. 

NORTH

Temperatures are either holding steady, or are already starting to rebound a bit across the north region, following the latest surge of colder air from the northwest, as the air mass moderates under the ever-increasing sunshine. A moderate storm system riding along the frontal boundary to the east of Japan will bring quite a bit of cloudiness to the central prefectures of the nation. A new, weaker ripple of energy coming in from eastern China will pass along the boundary over the next 24 hours, bringing clouds and few showers to the southern islands of the archipelago. Moisture is also riding over the cooler air mass at the surface over portions of central and eastern China, helping keep skies cloudy and temperatures cool in these areas.

CENTRAL

The central region is also feeling the new cool surge as it drops down from the north, and pulls up just short of the south region. Temperatures have been tumbling through the overnight hours, and will continue to fall for the remainder of the day. The aforementioned weak storm system forming along China’s eastern coast will help clouds and rainfall form over the southeastern coast and over Taiwan. A few showers will fall in the west where moisture is overriding the cool air at the surface, and in the south, where the stationary frontal boundary is helping to create some lift and squeeze out a few drops of rainfall.

 SOUTH

More intense heat is in store for the south region, especially over inland portions of Indochina, as the summer-like heat continues to build. Coastal locations of Southeast Asia are seeing slightly cooler temperatures, but it will still be quite hot. A stationary frontal boundary located just north of the Philippines may provide enough energy for some showers and scattered thunderstorms to develop in the northern portions of Luzon. Singapore will also see another daily dose of thunderstorms in the midst of the afternoon heat.

TROPICS 

The tropics remain quiet, as one would expect entering the second week of March. The I.T.C.Z. (Inter-Tropical Convergence Zone) is still depressed in location, and available moisture, so activity is isolated to just weak waves of energy passing through western Micronesia, eastern Micronesia, and the Marshall Islands. The Mariana Islands and Wake Island are still dealing with pulses of continental energy, with cooler temperatures than locations to the south.

Have a thrilling Thursday!
