Weekend weather brief – January 7/8, 2017

NORTH

High pressure will build into the northernmost reaches of the north region today, keeping temperatures frigid over Mongolia, northern China, and southeastern Russia. This high pressure will continue to strengthen over the next several days, ushering in some of the season’s coldest air next week. Air quality will be hazardous in Beijing and north-central China as light winds and stagnant air remain in place. One weak impulse of energy is moving through northern Japan, while another weak storm system will exit central China into the Korean peninsula and Japan this weekend, bringing a good chance for showers and occasional heavy rainfall to these areas. Eastern China will also see a rather damp weekend as the tail-end of a stalled frontal boundary lingers overhead.

CENTRAL

Moisture streaming in from the southwest will combine with a weak impulse of energy moving through central and eastern China, and a stalled frontal boundary just offshore, to bring a good chance for clouds and showers to much of the region this weekend. The best conditions will be along the coast of southeastern China, where a mix of clouds and sun are on tap. Temperatures will be seasonably warm this weekend ahead of a cool-down that will arrive next week.

SOUTH

The south region will see a mixed bag of weather as the drier air moderates a bit over Indochina, and a new tropical disturbance brings clouds and rain to the southern Philippines, while the northern Philippines enjoys a mix of clouds and sunshine. Skies over the Southeast Asian peninsula will clear on Sunday, while areas to the south remain enveloped in deep tropical moisture both days. Temperatures will be seasonably warm across the region with the slightly increased solar angle as the sun begins its daily climb to the north in earnest.

 

TROPICS 

Tropical disturbance 96W INVEST has been declared tropical depression “Auring” by PAGASA…continues to threaten the southern Philippines with a rainy weekend…

96W INVEST is looking a little healthier this weekend as the Philippines’ state weather agency PAGASA designates the system tropical depression “Auring”. The system will bring copious amounts of rainfall to the island of Mindanao and the southern Visayas of the Philippines, which could use the rain following an extended period of drought, but needs that rain to be slow and steady to avoid any major ill-effects. Some localized flooding and landslides are possible, due in part to the predominantly mountainous terrain that dominates the islands. PAGASA has issued the following TCWS signals:

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

Agusan del Sur, Agusan del Norte, Surigao del Sur, Surigao del Norte and Dinagat Island Province.

Current forecast models are indicating that this system will remain weak as it passes through the archipelago and into the Sulu Sea early next week. For more information on this system, please refer to the “Western Pacific Tropical Update” by meteorologist Mike Adcock on this site.

The remainder of the tropics will see a good chance for showers and scattered thunderstorms as tropical moisture dominates locales below 10 degrees latitude, and incursions of instability from continental air masses affect more northerly locales.

 

Have a wonderful weekend!
