Weekend update- March 19-20, 2016

NWPAC outlook, 19/20 MAR

NWPAC outlook, 19/20 MAR

Cooler air settles into the north region while the central stays warm but prepares for similar changes in the next few days. Dangerous heat is set up in the south, and while the tropics are warming up, there’s nothing out there to keep an eye on yet.


Cooler air is migrating slowly through the north region this weekend as the last of a series of weak frontal boundaries to pass through the region do so. High pressure to the east of Mongolia is allowing return flow to moderates temperatures already, but areas to the south and east will see a general cooling trend this weekend. A storm system currently passing along the eastern seaboard of Japan will bring some showers to Tokyo and parts of eastern China Saturday, with improving weather on Sunday. Moisture riding in along the jet stream will pull some clouds over parts of western China, but no precipitation is expected. The remainder of the region will see nice weather this weekend, with a mix of clouds and sun.

City Sat. High C (F) Sun. High C (F) Conditions (Sat/Sun)
Ulaanbaatar 9 (48) 11 (52) Fair/Partly Cloudy
Vladivostok 8 (46) 8 (46) Partly Cloudy/Fair

Xi’an 28 (82) 19 (66) Fair/Cloudy
Shanghai 17 (63) 16 (61) Rain/Fair



The central region will see temperatures hold steady this weekend as high pressure stays well north of the region, with a cooling trend coming up in the middle of next week. A storm system currently passing along Japan’s eastern coastline is dragging a weak frontal system behind it, stretched back over portions of Taiwan and southeastern China. This frontal system will allow for the development of some showers in these areas through tomorrow. Portions of northern Vietnam could see some scattered thunderstorms during the peak of afternoon heating Saturday, but otherwise, mostly pleasant weather will dominate the central region through the weekend.

Dangerous heat continues in the south region, especially over portions of the interior southeastern Asian peninsula. One would think that hot weather is the norm, and by all accounts that would be true. However, sustained heat of this magnitude is rarely seen even over these areas, so advisories are justified. As we pass through the Vernal Equinox on Sunday, the sun’s noontime angle will increase, and the direct sunlight will help to continue the intense afternoon heating for the next 10 days or so. Clouds will be few and far between for most of the region this weekend, with only a few scattered thunderstorms expected near Singapore on Saturday.

The tropics are still very quiet, thankfully, with very little in the way of convergent activity within the I.T.C.Z. (Inter-Tropical Convergence Zone). Aside from some showers for the Mariana Islands and Wake Island due to continental air masses sliding through, the region will see a great deal of sunshine with only a few scattered clouds.
