Daily weather brief – Tuesday, November 29, 2016

NWPAC outlook, 29 NOV

NWPAC outlook, 29 NOV

NORTH

The cold, wintry air mass stays locked in over portions of the north region today as temperatures struggle to get into the teens over southern and eastern locales, and stay well below zero far to the north. A weak impulse of energy will bring low clouds and foggy conditions to eastern China as the warmer air from the south rides over the cooler surface layer. Haze and smoke will be an issue across Mongolia as high pressure overhead creates a bit of a stagnation problem. The remainder of the region should see a rather nice, albeit chilly, day ahead.

CENTRAL

Temperatures are rebounding a bit across the central region as the high pressure system responsible for the attest Siberian surges tracks mostly eastward. A few showers will fall over the higher terrain of south-central China and across Taiwan as the strong northeasterly flow rolls the moisture up the mountains, squeezing out a few showers. Skies will be partly cloudy across Okinawa, and over southern China and northern Indochina, while temperatures will settle in at comfortably warm autumn levels over much of the region.

SOUTH

A new surge from the north has infiltrated much of the south region, with high pressure building in behind a strong northeasterly flow over portions of northern Indochina and the northern Philippines. Locations to the south will see another round of afternoon showers and thunderstorms as the drier air fails to make its way to those locales. Temperatures will be very warm across much of the region, especially over southern Indochina where warm air advecting northward ahead the newest surge will heat things up a bit.

TROPICS

The tropics have quieted down significantly following the demise of tropical storm TOKAGE, and due to drier filtering into the region from the north.

TAAG, 29 NOV

TAAG, 29 NOV

The remnants of TOKAGE, although hard to spot, continue to push slowly to the southwest over the South China Sea. A new surge of cooler air from the north will dry out the western tropics, while a recent northerly surge has cleared things out quite nicely over eastern and northern portions of the region. Long-range computer models are showing no development of any significant tropical systems for the foreseeable future. Over all, scattered pockets of instability will combine with the available moisture and warm sunshine to generate a few scattered thunderstorms in spots, especially over western Micronesia.

Daily weather brief – Monday, November 28, 2016

NWPAC outlook, 28 NOV

NWPAC outlook, 28 NOV

NORTH

Cold air remains in place over the north region as the transition from autumn to winter continues. The leading edge of the cold air mass has swept over Japan, and is moving to the east, bringing clear to partly cloudy skies across much of the region. The exceptions would be central China, where a weak disturbance is sliding through, bringing cloudy conditions, and also in eastern china, where low clouds and fog will make for a rather dreary day. Temperatures will once again range from below zero in the northernmost locales, to the low and middle teens to the south and east.

CENTRAL

Temperatures remain comfortably mild across the central region as the latest surge from the north slide well to the south of the region. Scattered showers are possible over the high country of southern China as moisture gets pumped in from the west along the jet stream, and also over Taiwan, as the strong northeasterly flow drags moisture up the higher terrain. The remainder of the region will see plenty of sunshine and just a few scattered clouds here and there.

SOUTH

Conditions are considerably drier across Indochina today as the latest surge brings in a strong northeasterly flow across the peninsula. Portions of northwestern Philippines will see a chance of rain as the system formerly known as tropical storm TOKAGE gets torn apart by the incoming surge.  Locations to the south can also expect a good chance for scattered afternoon showers and thunderstorms as the air mass remains moist and the sun continues to heat up the midday.

TROPICS

The remnants of tropical storm TOKAGE continue to unravel northwest of the Philippines while the remainder of the region sees activity wane a bit.

TAAG, 28 NOV

TAAG, 28 NOV

J.M.A. (Japan Meteorological Agency) has downgraded tropical storm TOKAGE, also named “Marce” by the Philippines’ state weather agency PAGASA, to tropical depression status as the system encounters very hostile conditions care of a strong northerly surge coming in. V.W.S. (Vertical Wind Shear) has increased to above 25 knots over the system, and has literally sheared off the heaviest convection far to the northeast, leaving the L.L.C.C. (Low-Level Circulation Center) a bit exposed. To make matters worse for the system, the circulation is dragging in very dry air from the north, compliments of the prevailing surge moving southward into the area. Forecasts continue to show the system weakening, with the weak, remnant low being pushed to the west-southwest over the next 24 hours by the strong flow of the Siberian surge, with complete dissipation expected within the next 48 hours.

29W full, 28 NOV

29W full, 28 NOV

Elsewhere across the tropics, a long trough of convergence extends through much of Micronesia, which will help fire off some scattered showers and thunderstorms across most locations in the Federated States, while far to the east, drier air has moved in, and taken rain chances out of the forecast for today.

Tokage Weakens After Wind Shear Tears It Apart

Tokage has lost its TS intensity this Monday after much of the convection in the storm being blown to the North East Away from the center of circulation.

tropical

In fact on Satellite imagery the shear on the storm is so strong it looks like Tokage is moving over Luzon but in fact the low level center is tracking west in to the south china sea. Being exposed due to the wind shear and ever increasing dry air do not expect much more out of Tokage.

 

Even the chance of it somehow re-generating is low, we will still watch it over the coming days but overall it seems it will continue to weaken. Do not be a boater venturing through the storms center just yet though, satellite derived winds show sustained well over 50kts still visible in Tokage’s center.
