NWPAC outlook 02 FEB

NWPAC outlook 02 FEB

High pressure brings colder air to the north and central regions, while the south continues to bake and the tropics go dead quiet. 


Cooler air continues to settle into the north region today, with lots of high pressure building in to keep the skies clear and the temperatures cold. Temperatures are moderating just a bit across most of the region today, but it’s still basically a deep-freeze scenario for most locations in the region. The latest storm system to affect the north is pulling away from Japan, and it looks like we will get a few days’ break form any significant weather action as temperatures warm up to more normal seasonal levels.

City High Temp C (F) Low Temp C (F) Conditions
Ulaanbaatar -14 (7) -29 (-20) Fair
Vladivostok -7 (19) -18 (0) Fair
Beijing 4 (39) -8 (18) Fair
Seoul 1 (34) -8 (18) Fair
Tokyo 9 (48) 0 (32) Partly Cloudy
Xi’an 6 (43) -7 (19) Fair
Shanghai 6 (43) -2 (28) Partly Cloudy



High pressure is also building into the central region, but the fair weather tendencies of the air mass are being negated a bit by overriding moisture streaming in from the west along the jet stream. This moisture is keeping a cloudy lid over most of the region, and also helping supply moisture for the latest storm system, which is exiting the region to the northeast. A cold front stretches back into southeastern China, and is a focusing mechanism for the moisture coming in. This will help bring a few showers to Hong Kong and make for quite a rainy day, once again, across Taiwan. Notable today is the lack of cloudiness in southern China and northern Indochina as cool temperatures settle in and a very nice day ensues.

City High Temp C (F) Low Temp C (F) Conditions
Kunming 8 (46) 3 (37) Cloudy
Hong Kong 12 (54) 11 (52) Showers
Taipei 13 (55) 11 (52) Rain
Iwo To 10 (50) 2 (36) Cloudy
Hanoi 14 (57) 10 (50) Partly Cloudy



More intense heat is expected in the south region, especially in southern Vietnam. The latest northerly surge has filtered into northern portions of the region, evidenced by the extreme diurnal temperature swings and a general cooling that has taken place in some locations. Average temperatures across the region will spike near 33C (91F) this afternoon as the days get just a little longer and the sun’s angle increases. Some moisture is present over the Philippines, so a few showers are possible in some spots across the archipelago, however, this air mass has been steadily drying over the past 48 hours, so any precipitation will be light and quite isolated. Singapore will also see another daily dose of thunderstorms to cool the afternoon heat. The remainder of the region will see just a few scattered clouds and plenty of intense sunshine.

City High Temp C (F) Low Temp C (F) Conditions
Siem Reap 33 (91) 19 (66) Partly Cloudy
Ho Chi Minh 34 (93) 24 (75) Partly Cloudy
Manila 33 (91) 23 (73) Partly Cloudy
Davao City 32 (90) 23 (73) Partly Cloudy
Brunei 31 (88) 26 (79) Partly Cloudy
Singapore 33 (91) 26 (79) Thunderstorms



The tropics are very quiet today, with no noticeable disturbances to track or monitor. Some residual moisture from a weak tropical wave is passing through western Micronesia and into the Philippines, but precipitation is very isolated and light. The more northerly locations of Guam and wake will see more influence from the continental air masses that keep sliding by, with a few clouds and showers possible. The remainder of the region will see a beautiful day, with scattered clouds and lots of bright sunshine!

City High Temp C (F) Low Temp C (F) Conditions
Guam 27 (81) 23 (73) PM Showers
