Daily weather brief – Friday, November 25, 2016

NWPAC outlook, 25 NOV

NORTH

Cold air stays in place over the north region as a new storm system gets wound up over central China, bringing another shot of wintry precipitation to parts of northern China and Mongolia. The resurgent cold front is draped across the central portions of East Asia making for a rather gloomy day across those locales. Below-zero and single-digit temperatures will once again be in store for most of the region, with only eastern China seeing temperatures creeping just into double digits.

CENTRAL

The newest surge of Siberian air has pulled up just short of the central region as a new storm system gets wound up along the frontal boundary. This storm system will usher in the surge to locations to the south over the weekend, bringing a noticeable nip to the air by the start of next week. Clouds and showers are prevalent across much of the region, with the coast of southeastern China seeing just a few clouds.

SOUTH

Tropical storm 1625/29W has been designated at its current status by all three agencies associated with updates as it moves through the central Philippines this morning. Heavy rain has been reported in several locations in the Visayas, along with some flooding and scattered landslides. The Philippines’ state weather agency, PAGASA, has issued the following T.C.W.S. (Tropical Cyclone Warning Signals) for portions of the country:

#1 (30-60kph expected in 36 hrs)-

Northern Palawan including Cuyo Island, Rest of Oriental Mindoro, rest of Occidental Mindoro including Lubang Island and Masbate including Burias and Ticao Island, Biliran, Leyte, Northern Cebu including Bantayan and Camotes Islands, Negros Occidental, rest of Antique and Guimaras…

#2 (61-120kph expected in 24 hrs)-

Romblon, Calamian Group of Islands, Southern Occidental Mindoro and Southern Oriental Mindoro, Iloilo, Capiz, Aklan and Northern Antique…

29W, TCWS, 25 NOV

Please see more on the forecasts for this system in the ‘tropics’ section of this report. Elsewhere across the central region, warm sunshine and plentiful moisture will help generate a few scattered showers and thunderstorms across some locales as warm air advects northward ahead of the newest incoming surge, due to arrive next week.

TROPICS

Only one system in the tropics to deal with at this time, as the eastern half of the region dries out considerably.

TAAG, 25 NOV

Newly-designated tropical storm 1625 TOKAGE, also named “Marce” by the Philippines’ state weather agency PAGASA, continues to bring heavy rain and strong winds to portions of the Philippines. The system entered the country in the Visayan Islands and has tracked generally west-northwest over the past 24 hours. Some are have received flooding rainfall and gusty winds, with all the hazards associated with a tropical system. As of this time, there are no reports of deaths or injury. The system is expected to continue passing through the western Visayas, emerging into the South China Sea. Forecasts show this system to track is a slow arcing curve to the north ahead of an incoming cold surge from the north. This forecast would indicate that the system will remain weak and be influenced mostly by lower-level steering mechanisms. However, PAGASA’s forecast varies a bit, showing the system to turn more to the west, which would indicate steering influences from an extension of the S.T.R. (Sub-Tropical Ridge) to the north due to a stronger system core during that time. For now, residents of the Philippines can expect heavy rain to continue for portions of the western Visayas and southern Luzon as the systems’ life cycle continues.

29W full, 25 NOV

Elsewhere across the tropics, it has quieted down considerably over the region as drier air filters into the region from the north. Of course, in the tropics, ‘drier’ is a relative term, so the air will still be quite moist, allowing for a few scattered showers and thunderstorms to pop up across several locales.

Have a fabulous Friday!
