Daily update- Friday, February 12, 2016

NWPAC outlook, 12 FEB

NWPAC outlook, 12 FEB

Evidence of the newest Siberian surge is starting to show in parts of the north region, while the central region heats up more ahead of the new air mass. The south stays hot, with little relief in sight, and the tropics remain silent. 

NORTH

Cold air is starting to move into portions of northwestern China today as the latest Siberian surge flows slowly to the east and south. Temperatures out ahead of the new air mass will continue to warm up before the surge moves through northwestern areas of the region by Saturday and in the southern and eastern areas on Sunday. A storm system is developing over eastern China, and will slide through Korea and Japan this weekend and pull the surge eastward into those locales. Temperatures from this surge will fall nearly 13C in some places across the north region by early next week.

City High Temp C (F) Low Temp C (F) Conditions
Ulaanbaatar -16 (3) -30 (-22) Fair
Vladivostok -2 (36) -6 (21) Freezing Rain
Beijing 11 (52) 1 (34) Rain
Seoul 12 (54) 6 (43) Rain
Tokyo 14 (57) 9 (48) Partly Cloudy
Xi’an 7 (45) -2 (28) Showers to Snow
Shanghai 23 (73) 14 (57) Increasing Clouds

 

CENTRAL

Temperatures across the central region will continue to warm up ahead of the new surge, which should arrive across most of the central region on Sunday and Monday. Significant temperature changes will take place, especially over the more northerly and easterly locales, while less effect will be felt to the south and west. A storm system forming over eastern china will help pull up some clouds and moisture over eastern portions of the region.

City High Temp C (F) Low Temp C (F) Conditions
Kunming 18 (64) 7 (45) Fair & Windy
Hong Kong 23 (73) 19 (66) Cloudy/Foggy
Taipei 26 (79) 17 (63) Partly Cloudy
Iwo To 12 (54) 8 (46) Rain
Hanoi 31 (88) 16 (61) Partly Cloudy

 

 SOUTH

Portions of the south region continue to see record-setting heat, especially over Cambodia and southern Vietnam. The Philippines will be warm in western provinces, but eastern and southern provinces will see a strong, moist northeasterly flow, with clouds and showers likely for coastal areas. Brunei, Indonesia, and Malaysia will also see quite a bit of moisture for the warm afternoon sun to transform into clouds and scattered thunderstorms.

City High Temp C (F) Low Temp C (F) Conditions
Siem Reap 36 (97) 22 (72) Partly Cloudy
Ho Chi Minh 34 (93) 23 (73) Partly Cloudy
Manila 33 (91) 22 (72) Fair
Davao City 33 (91) 23 (73) Sctd. Showers
Brunei 31 (88) 26 (79) Sctd. T-storms
Singapore 32 (90) 26 (79) Cloudy

 

TROPICS 

The tropics are still very quiet as we enter the middle of February. Activity along the I.T.C.Z. (Inter-Tropical Convergence Zone) is widely scattered and unfocused, with a very weak easterly wave located near the Marshall Islands, a second weak wave south of western Micronesia, and a third, slightly stronger wave drifting through Indonesia, Brunei, and Malaysia. Clouds and showers will be focused a bit in these areas. Clouds and showers will also affect the Mariana Islands and Wake as continental energy slides through both locations.

City High Temp C (F) Low Temp C (F) Conditions
Guam 26 (79) 22 (72) Showers & Windy
Yap 30 (86) 24 (75) Showers
Palau 31 (88) 25 (77) Increasing Clouds
Chuuk 29 (84) 26 (79) Partly Cloudy
Pohnpei 30 (86) 26 (79) Partly Cloudy
Majuro 29 (84) 26 (79) Partly Cloudy
Wake 27 (81) 22 (72) Increasing Clouds

Have a fabulous Friday!

Daily update- Thursday, February 11, 2016

NWPAC outlook, 11 FEB

NWPAC outlook, 11 FEB

It’s a veritable see-saw of meteorology across eastern Asia today as another cold shot of Siberian air starts to infiltrate parts of the north region, while temperatures warm up big time ahead of the surge in the central and the south. 

NORTH

Colder air is starting to make way into portions of Mongolia and northern China today, the leading edge of what should be a fairly strong winter surge that will affect most of eastern Asia over the next 3-5 days. The north region will start to cool off today and tomorrow as the air mass slides to the south and east, bringing plenty of cold air to the region. Warm, moist air out ahead of the air mass will help temperatures rise and clouds and showers forming in northeastern China and Korea through tomorrow. Temperatures will increase a bit across the more southerly areas of the region, before starting to drop significantly tomorrow and Saturday.

City High Temp C (F) Low Temp C (F) Conditions
Ulaanbaatar -9 (16) -28 (-18) Snow Showers
Vladivostok 2 (36) -4 (25) Partly Cloudy
Beijing 10 (50) -3 (27) Cloudy
Seoul 14 (57) 4 (39) Cloudy
Tokyo 10 (50) 3 (37) Fair
Xi’an 16 (61) 5 (41) Increasing Clouds
Shanghai 22 (72) 12 (54) Rain

 

CENTRAL

The central region is warming up BIG TIME, as the very warm air from the southerly latitudes gets pulled up ahead of the new incoming cold surge to the north. This warm air is also quite moist so clouds, and a few showers, are evident across the southeastern portion of the region. The incoming cold surge will begin to affect the central region this weekend, with temperatures falling on Sunday and Monday. The surge will not be as strong as the one we had earlier in the month, but it will provide significant relief from the current warming trend across the region as we head into next week.

City High Temp C (F) Low Temp C (F) Conditions
Kunming 18 (64) 7 (45) Fair & Windy
Hong Kong 21 (70) 18 (64) Cloudy/Foggy
Taipei 25 (77) 17 (63) Rain
Iwo To 13 (55) 2 (36) Fair
Hanoi 27 (81) 16 (61) Partly Cloudy

 

 SOUTH

As warm air gets pulled up into the areas to the north, even WARMER air is building across Southeast Asia. Temperatures across southern Vietnam and Cambodia will be torrid once again today under generally clear skies, peaking near 35C (95F) this afternoon. It will be considerably cooler across the remainder of the south region, as high pressure keeps a moist, and cooler, flow across the Philippines, where a few showers could fall in the southern locales. A few scattered thunderstorms are also possible for Singapore as the moisture heats up in the afternoon sun.

City High Temp C (F) Low Temp C (F) Conditions
Siem Reap 35 (95) 21 (70) Fair
Ho Chi Minh 35 (95) 23 (73) Partly Cloudy
Manila 31 (88) 22 (72) Fair
Davao City 32 (90) 23 (73) Sctd. Showers
Brunei 31 (88) 25 (77) Partly Cloudy
Singapore 32 (90) 26 (79) Sctd. T-storms

 

TROPICS 

The tropics are once again very quiet today, with no development in sight. The I.T.C.Z. (Inter-Tropical Convergence Zone) is in a quiet state, typical for this time of year. A few ripples of weak energy are located throughout the region, so a few clouds and showers could pop up here and there. The Mariana Islands and Wake will be dealing with more influence from continental weather systems as we go through the next 3-5 days, so clouds will be numerous and the wind will likely be picking up in these locations.

City High Temp C (F) Low Temp C (F) Conditions
Guam 27 (81) 22 (72) Cloudy & Windy
Yap 30 (86) 25 (77) Increasing Clouds
Palau 31 (88) 25 (77) Partly Cloudy
Chuuk 29 (84) 26 (79) Decreasing Clouds
Pohnpei 31 (88) 26 (79) Partly Cloudy
Majuro 29 (84) 27 (81) Showers & Windy
Wake 27 (81) 23 (73) Partly Cloudy

Have a great Thursday!
