Daily weather brief – Friday, September 23, 2016

NWPAC outlook, 23 SEP

NORTH

Cooler air surges southward over the north region as the signs of autumn begin to show. The first rather dry frontal system has pushed through, clearing the way for the next cooler surge to move down through the weekend. The new front will bring some thundershowers to Mongolia and northern China, and the early front will linger over Japan today, offering up a good chance for showers across Honshu.

CENTRAL

The early surge mentioned in the previous section has pushed all the way down into southern China, stretching back to the northeast and offshore towards Japan. The weak front will be a focal point for existing moisture, squeezing out some showers and thunderstorms across portions of northern Indochina, and offshore over Okinawa. Clouds will linger over the highlands south south-central China, while the remainder of the region enjoys partly cloudy skies.

SOUTH

The south region will see another day of numerous showers and thunderstorms as plentiful moisture gets a lift from the afternoon sun. Attention remains on tropical disturbance 96W INVEST as forecasts show it moving into the region this weekend.

TROPICS

Two strong disturbances are out in the tropics now; with newly designated Tropical Storm MEGI and 97W INVEST system.

TAAG, 23 SEP

96W INVEST has been declared Tropical Storm MEGI by J.M.A. (Japan Meteorological Agency). This system has been a bit of an enigma over the past 24 hours. The J.T.W.C. (Joint Typhoon Warning Center) has re-issued the T.C.F.A. (Tropical Cyclone Formation Alert) having relocated the system to the NW, more in line with J.M.A.’s relocation earlier in the day. Computer forecast models are still showing a significant system forming and moving to the WNW in the general direction of the Luzon Strait and Taiwan next week.

20W full, 23 SEP

97W INVEST was designated yesterday, far to the east in the eastern Micronesia/Marshall Islands vicinity. Computer forecast models do show development of this system next week and a general track to the NW towards southern Japan.

97W, 23 SEP

Elsewhere across the region, showers and thunderstorms will be plentiful as the deep tropical moisture gets heated up by the intense afternoon sunshine.

Have a fabulous Friday!
