Daily weather brief – Tuesday, August 30, 2016

NWPAC outlook, 30 AUG

NORTH

The big story in the north region is Typhoon 12W LIONROCK, which has northern Honshu Island of Japan in its sights. The system continues to lose its steam due to various unfavorable conditions, and will continue to weaken through the remainder of its life-span. LIONROCK is expected to make landfall somewhere near Sendai as a tropical storm-strength system, and track quickly across the island and into mainland Asia somewhere near the Russia-China border sometime tomorrow. Heavy rain, gusty winds, and even a few landslides are possible in parts of northern Japan as the system blasts through. Elsewhere across the region, an early-season cold front has swept through much of the north region, backing temperatures down off of the very high readings of the previous 2 weeks. Temperatures will reflect an autumnal feel in Mongolia, while everyone else will just see some relief from the heat. Aside from the stormy weather in northern Japan, we will see some showers in Tokyo, and thunderstorms in southeastern Russia, but everyone else will see good conditions this afternoon.

City	High/Low C		High/Low F		Conditions
Ulaanbaatar	21	7	70	45	Partly cloudy
Vladivostok	26	19	79	66	Thunderstorms possible
Beijing	31	18	88	64	Partly cloudy
Seoul	26	17	79	63	Partly cloudy
Tokyo	29	23	84	73	Scattered showers likely
Xi’an	31	21	88	70	Partly cloudy
Shanghai	30	22	86	72	Mostly fair

 

CENTRAL

The weather in the central region has cleared out for the most part, with relatively normal temperatures expected today. A few afternoon showers and thunderstorms could pop up near Hong Kong, and over the high country of south-central China. Otherwise, it will be a fine day across the region with lots of sunshine.

City	High/Low C		High/Low F		Conditions
Kunming	24	17	75	63	Scattered thunderstorms possible
Hong Kong	31	27	88	81	Scattered showers possible
Taipei	32	24	90	75	Mostly fair
Naha	30	27	86	81	Mostly fair
Hanoi	32	26	90	79	Partly cloudy

 

SOUTH

Aside from the general deep tropical moisture that remains locked over the south region this time of year, it will be a relatively quiet day across the south region as well. 12W LIONROCK has exited the scene far to the north, and has taken much of the excess moisture and energy with it. We do have one weak trough over northern Luzon in the Philippines, which will fire off some spots of heavy rain over the northwestern provinces of the island through the day. The rest of the region will see the usual dose of afternoon showers and thunderstorms as the moisture in place gets a lift from the intense afternoon sun.

City	High/Low C		High/Low F		Conditions
Siem Reap	32	26	90	79	Thunderstorms likely
Ho Chi Minh	32	25	90	77	Thunderstorms likely
Manila	31	26	88	79	Scattered thunderstorms possible
Davao City	32	24	90	75	Scattered thunderstorms possible
Brunei	33	24	91	75	Thunderstorms possible
Singapore	31	26	88	79	Thunderstorms likely

 

TROPICS

As the M.J.O. phase enters a decidedly non-active phase, we find much of the activity and moisture absent from the tropics today with only Typhoon 12W LIONROCK to watch as it moves into northern Japan later today.

TAAG, 30 AUG

Typhoon 12W LIONROCK is spinning around to the east of Japan, and is expected to continue to track in an arc to the NW and across the northern half of Honshu in Japan later this afternoon. The system is expected to continue to lose strength as it enters cooler SST’s (Sea-Surface Temperatures), and increasing VWS (Vertical Wind Shear), with the final gut-punch coming as it makes landfall later. The system is expected to track quickly across Japan and into mainland Asia near the China-Russia border sometime tomorrow.

12W full, 30 AUG

Elsewhere across the tropics, there are no official areas to be concerned about as it has gone stone-cold quiet out there. Deep moisture and scattered pockets of energy will help bring a chance of afternoon showers to most locations; however, coverage is not expected to be significant.

City	High/Low C		High/Low F		Conditions
Guam	31	26	88	79	Thunderstorms possible
Yap	31	26	88	79	Scattered thunderstorms possible
Palau	29	27	84	81	Scattered thunderstorms possible
Chuuk	30	26	86	79	Partly cloudy
Pohnpei	29	21	84	70	Scattered thunderstorms possible
Majuro	29	27	84	81	Scattered thunderstorms possible
Wake	29	27	84	81	Thunderstorms possible

 

Have a terrific Tuesday!
