Weekend weather brief – January 14/15, 2017

NWPAC outlook, 14/15 JAN

NORTH

A complex weather scenario will play out over the eastern third of the north region as a nearly-stationary, and very strong, upper-level low pressure system spins over southeastern Russia. This system will push down waves of cold air and instability over the southeastern Russia, and especially Japan, where the sea-effect snow machine is running at full speed. From Hokkaido south to central Honshu along the Sea of Japan, and especially over the higher terrain of central Honshu, epic amounts of snowfall will settle in as this weather situation plays out over the weekend. Many areas are under avalanche advisories as the heavy snow accumulates along the steep mountain slopes. To the south and west, conditions are cold, but better, as high pressure dominates these locales. Air quality in Beijing will be decent today, but will start to deteriorate as the weekend progresses. Temperatures will be frigid across the northern third of the region and quite chilly in the lower two-thirds with afternoon highs remaining in the single digits C (30’s-40’s F).

CENTRAL

Moisture streaming in from the southwest which is helping to fuel the complex weather scenario to the north will also bring about significant cloud cover and shower activity over the central region through the weekend. Aside from mostly fair conditions over the higher terrain of south-central China, the remainder of the region will see a gloomy weather situation play out. Temperatures will remain mild, ranging from the mid-teens to lower 20’s C (low 60’s to near 70 F) but with the lack of sunshine, it will feel a bit clammy and chilly across most of the region.

SOUTH

Moisture associated with what remains of TD01W will affect southern Indochina through the weekend as the system falls apart and spreads moisture westward across the peninsula through the weekend. Tropical moisture from the rapidly-decaying 97W INVEST near the Philippines will also bring about scattered showers and thunderstorms to the central and northern provinces of the archipelago. Deep tropical moisture remains locked in over the southern half of the region, and will help generate scattered showers and thunderstorms over many of these locales. Temperatures will be quite warm as afternoon highs climb into the lower 30’s C (upper 80’s to near 90 F) region-wide.

TROPICS 

01W and 97W INVEST continue to deteriorate as the tropics quiet down region-wide…

TAAG, 14 JAN

Although still listed as a tropical depression on the J.M.A. (Japan Meteorological Agency) surface map, what remains of 01W is falling apart just east of Vietnam and is spreading moisture to the west over southern Indochina and to the northeast along a fading surge boundary over the northern South China Sea. This system will continue to break down and feed moisture into the area through the weekend. What remains of 97W INVEST is doing much of the same to portions of the central Philippines, as much of the moisture from this system is being ejected to the northeast by an incoming continental surge to the north. Overall, both systems are expected to carry on with a general downward trend for the foreseeable future, but will bring rainfall to the affected areas as the remnant moisture keeps moving generally to the east as the seasonal northeast monsoon pushes it along.

01W/97W full, 14 JAN

The remainder of the region will see a mix of sunshine, clouds, and few scattered thunderstorms as pockets of moisture get heated up by the ever-increasing afternoon sunshine. Temperatures will be uniformly mild across the region, with highs generally in the upper 20’s to low 30’s C (mid to upper 80’s F).

Daily weather brief – Friday, January 13, 2017

NWPAC outlook, 13 JAN

NWPAC outlook, 13 JAN



NORTH

Very cold air continues to dominate much of the north region today as we head into the weekend. The big story this weekend is the snowfall expected in parts of western Japan as the latest storm system drags in very cold air over the relatively warmer Sea of Japan, and gets a lift from the topography throughout the western and central prefectures. This scenario is forecast to bring about a significant snowfall event over these areas, leading to the potential for avalanches in the mountainous terrain. Anyone planning to visit these areas over the weekend should exercise extreme caution.

JAPAN snow outlook, 13 JAN

JAPAN snow outlook, 13 JAN



Elsewhere across the region, clouds and a few snow showers are likely over southeastern Russia and the Korean Peninsula, while fog and low clouds will keep conditions cool and clammy across eastern china. Air quality across Beijing continues to degrade and stagnant air and high pressure remain locked in.

Clouds and showers will dampen sprits over the central region as a frontal system remains stalled out over the region. The heaviest precipitation will be found over the Ryukyu Islands, while scattered showers will prevail to the south and west as far as northern Indochina. Temperatures will be held back a bit by the cloud-cover and rain, with most locations only reaching the mid to upper teens C (low-mid 60’s F).

SOUTH

The south region is dealing with two major plumes of moisture associated with tropically-oriented systems as the remnants of 01W move into Indochina, and moisture from the degrading 97W INVEST moves into the Philippines. Most of the rainfall will begin this weekend in Vietnam, Cambodia, and eastern Thailand, but parts of the Philippines has already seen the rainfall begin.

WPAC TPW, 13 JAN

WPAC TPW, 13 JAN



To the south, plentiful tropical moisture remains in place, lending to a good chance for afternoon showers and thunderstorms. Where the sun shines the most, temperatures will be very warm, while the remainder of the region will also see highs in the lower 30’s C (Near 90 F).

TROPICS

01W and 97W INVEST continue to weaken as the atmosphere continues to dry out over much of the tropics…

TAAG, 13 JAN

TAAG, 13 JAN



01W, which JMA still labels a tropical depression on surface maps, has basically fallen apart due to strong wind shear and dry atmospheric conditions. This system will continue to degrade as it gets pushed to the west-southwest by the strong seasonal northeast monsoon. 97W INVEST has also been showing signs of degradation, as the convection has separated from the very weak surface low pressure, and has been pushed to the west by the strong northeast monsoon. This system is currently bringing rainfall to the eastern Visayas in the Philippines, and this moisture will slide across the Visayas and southern Luzon over the weekend.

01W/97W full, 13 JAN

01W/97W full, 13 JAN

Elsewhere across the tropics, much of the moisture has been carried away to the west by the most recent disturbances, and as the recent M.J.O. (Madden-Julian oscillation0 phase wanes and drier air comes in from the north, we find most of the remaining moisture to be located well below 10 degrees latitude. Most locations across the tropics can expect a chance for scattered showers and thunderstorms today, but the action will be quite isolated and light. For more information on the tropics, please refer to the “Western Pacific Tropical Update” by meteorologist Mike Adcock on this website.

Dialy weather brief – Thursday, January 12, 2017

NWPAC outlook, 12 JAN

NWPAC outlook, 12 JAN



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.

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).

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.

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…

TAAG, 12 JAN

TAAG, 12 JAN



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.

01W/97W full, 12 JAN

01W/97W full, 12 JAN



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.
