Daily weather brief – Tuesday, August 30, 2016

NWPAC outlook, 30 AUG

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.

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.

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.

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

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

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.
