Another Strong Low, Snow or Rain? Weekend Snow Outlook Feb 19th 21st

Another potent winter storm is rolling over Japan this coming weekend bringing warming temperatures and wide spread rainfall. The good news is that this storm will be slightly colder than last weeks meaning the tops of the mountains across Nagano and Niigata should be cold enough for some decent amount of snow to fall.

 

Those across the Pacific coast of Japan will see a surge of strong southerly winds as well pushing temperatures in to the high teens about 6-8 degrees above average on Friday and Saturday.

This will come along with heavy rainfall though by Saturday afternoon in to the evening hours associated with the passing low. Behind it things will cool down dramatically as a large cold high dives in out of Siberia. So the warm up will be short lived for Japan and Korea as things start to look more “winter” like by Sunday in to Monday. If you want to enjoy what is left of winter through the rest of this and next month check out Tokyosnowclub. A fun and easy way to get in to the mountains in Japan.

 

(For those looking for information on the tropics, its still calm out there so nothing to worry about, enjoy the down time in the typhoon activity)

NWPAC outlook, 18 FEB

NWPAC outlook, 18 FEB

Small surges of cooler air continue to propagate across the north region, while temperatures across the central warm up just a bit ahead of a slight cool-down this weekend. The south continues to bake in the late winter sun, and the tropics are damp, but mostly quiet in terms of significant activity. 

NORTH

Temperatures are mixed across the north region, as cooler air infiltrates portions of Mongolia and northern China behind a frontal system, while locations to the east and south warm up a bit ahead of the incoming air mass. Conditions are mostly fair across the north region, as the frontal system that is passing through is relatively dry at the surface. The cooler air mass will press on through the entirety of the region over the next couple of days, bringing slightly cooler, but seasonable, temperatures to most locales.

City High Temp C (F) Low Temp C (F) Conditions
Ulaanbaatar -11 (12) -23 (-9) Cloudy
Vladivostok 2 (36) -12 (10) Fair
Beijing 8 (46) -4 (25) Fair
Seoul 9 (48) -4 (25) Partly Cloudy
Tokyo 11 (52) 3 (37) Partly Cloudy
Xi’an 14 (57) -1 (30) Partly Cloudy
Shanghai 17 (63) 5 (41) Fair

 

CENTRAL

Temperatures across the central region are warming up ahead of the next frontal system and cold air mass to the north. The cooler air will start to sweep down into the region this weekend, bringing temperatures down to more seasonable levels for the late winter season. Southeastern China and Taiwan will see clouds and rain today as high pressure to the north pushes moisture into the area from the east, however, most other locations across the region will see just a few clouds. The newly-developing surge I spoke of yesterday is bringing some strong winds to portions of western China, which will continue as the new air mass builds up prior to passing through next week.

City High Temp C (F) Low Temp C (F) Conditions
Kunming 19 (66) 6 (43) Ptly Cloudy & Windy
Hong Kong 17 (63) 16 (61) Cloudy
Taipei 19 (66) 16 (61) Rain
Iwo To 11 (52) 2 (36) Fair
Hanoi 20 (68) 14 (57) Partly Cloudy

 

 SOUTH

Temperatures across Cambodia and southern Vietnam continue to stay very hot as the seasonal northeast monsoon brings in drier air to the area, clearing the skies for the increasing intensity of the afternoon sun. Eastern shorelines of Indochina and the northern Philippines will see clouds and showers and the monsoonal flow presses a shallow layer of moisture into these areas, but once lifted over coastal mountain ranges, the air dries out considerably on the lee sides, clearing the skies and warming the air. Singapore could see quite a bit of rainfall this afternoon, but all other major metropolitan locations will see fair to partly cloudy skies.

City High Temp C (F) Low Temp C (F) Conditions
Siem Reap 35 (95) 19 (66) Fair
Ho Chi Minh 35 (95) 22 (72) Fair
Manila 32 (90) 22 (72) Partly Cloudy
Davao City 34 (93) 22 (72) Partly Cloudy
Brunei 31 (88) 26 (79) Partly Cloudy
Singapore 32 (90) 26 (79) Rain

 

TROPICS 

The tropics remain mostly quiet in terms of significant system development, but moisture is starting to build across the region, and coupled with some weak pulses of energy sliding along the I.T.C.Z. (Inter-Tropical Convergence Zone) are helping to create clouds and some showers in some locales. The islands of Micronesia stand the best chance of rainfall today, as the current wave is quite elongated and not very well-defined. In the northern portions of the tropics, the Marianas and Wake Island continue to see mostly continental energy sliding through, with a few clouds and gusty winds.

City High Temp C (F) Low Temp C (F) Conditions
Guam 26 (79) 22 (72) Partly Cloudy
Yap 28 (82) 25 (77) Rain
Palau 31 (88) 25 (77) Scattered Showers
Chuuk 29 (84) 26 (79) Scattered Showers
Pohnpei 29 (84) 26 (79) Rain
Majuro 29 (84) 26 (79) Partly Cloudy

Have a great Thursday!
