Dialy weather brief – Thursday, January 12, 2017

NORTH

Very cold air remains over the northern half of the north region as a frontal system stalls to the west and slides slowly to the south and east over Japan and the Korean Peninsula. The front is draped over central Japan, and stretches back to the west into coastal northeastern China, with frigid conditions behind the front, and moderately warmer conditions ahead of it. Japan will see the warmest day ahead as they remain south of the front for the time being, but sea-effect snow will fall over the western provinces of northern Japan and over the higher terrain of northern and central Japan, and temperatures across the archipelago will start to fall significantly as the front passes through later this afternoon. While a few showers will fall over eastern China, the remainder of the region will see a pleasant, but very cold, day ahead. It should be noted that air quality conditions in Beijing will approach hazardous levels later this afternoon, at the peak of the busy day as the aforementioned frontal system stalls out overhead and air stagnation sets in.

City	High/Low C		High/Low F		Conditions
Ulaanbaatar	-18	-32	0	-26	Mostly fair
Vladivostok	-11	-23	12	-9	Mostly fair
Beijing	5	-6	41	21	Mostly fair/Hazardous air quality
Seoul	2	-8	36	18	Partly cloudy
Tokyo	11	2	52	36	Mostly fair
Shanghai	9	2	48	36	Scattered showers likely

 

CENTRAL

The central region will see a wet day ahead as moisture funnels in from southwest along the energy channel feeding the latest frontal system that moved through. Taiwan will see the heaviest rainfall associated with this system, while the Ryukyu Islands and continental Asia will see scattered showers. Southern China and northern Indochina will see some periods of rain as well, as tropical moisture from the east slide into the region and interacts with drier surge-oriented air from the north. Temperatures will be cool to mild across the region, with high ranging from the mid-teens C (low 60’s F) to the lower 20’s C (low 70’s F).

City	High/Low C		High/Low F		Conditions
Kunming	16	7	61	45	Scattered showers likely
Hong Kong	19	16	66	61	Scattered showers likely
Taipei	22	17	72	63	Periods of rain
Naha	20	17	68	63	Scattered showers likely
Hanoi	15	13	59	55	Periods of rain

 

SOUTH

Rainfall associated with 01W has moved out of the northern Philippines, and drier air is settling in over the area, as well as over central and southern Indochina, reducing rainfall potential for these areas. Tropical moisture remains over the southern half of the region, and will get another healthy shot from 97W INVEST, which is slowly making its way into the region from the east. Showers and scattered thunderstorms are likely over the southern Philippines, northern Indonesia, Brunei, Singapore and the Malay Peninsula today as the warm sunshine lifts up the plentiful moisture in place. Temperatures will be quite warm over the entirely of the south region, especially in areas with fewer clouds.

City	High/Low C		High/Low F		Conditions
Siem Reap	33	23	91	73	Partly cloudy
Ho Chi Minh	33	24	91	75	Partly cloudy
Manila	30	24	82	75	Partly cloudy
Davao City	31	23	88	73	Scattered thunderstorms likely
Brunei	33	24	91	75	Scattered thunderstorms likely
Singapore	32	24	90	75	Scattered thunderstorms likely

 

TROPICS

Remnants of TD01W have re-generated over the South China Sea while the weak disturbance known as 97W INVEST continues to move through western Micronesia…

The disturbance formerly known as TD01W has improved, and J.M.A. has re-classified the system as a TD once again. The general forecast trend takes this system into southern Vietnam over the next couple of days. 97W INVEST has once again flared up as it trods westward. The system is currently located to the west-northwest of Palau Island; however, a large shield of convection is displaced to the north of the system, and stretches far to the west of the center. This moisture will start to affect southern and central Philippines today, and last through the weekend. Forecasts show this system to remain weak as it passes through the archipelago.

The remainder of the region will see a good chance for scattered showers and thunderstorms under a warm afternoon sun, while easternmost locales should see just a few scattered clouds. For more information on the tropics, please refer to the “Western Pacific Tropical Update” by meteorologist Mike Adcock on this website.
