EARLY WINTER STORM DOMINATES JAPAN

Surface Analysis Wednesday Morning

Surface Analysis Wednesday Morning

A dangerous and potent storm is dominating Japan today dropping some early season snowfall from Hokkaido all the way south in the mountains of Central Honshu towards the west of Tokyo.

 

Even in Hakuba snow was reported for the first time this season Tuesday morning while blizzard conditions were seen in the mountains of Yuzuawa. This webcam shows what it looks like at the top of Kagura.

In the hardest hit areas expect up to 40cm of total snowfall to take place, especially in western parts of Hokkaido.

 

The snow along coastal areas is also being accompanied by high winds, in northern Hokkaido at Souyamisaki winds were reported up to 113kph. This is a result of a high pressure gradient from the low north of Hokkaido interacting with the cold massive high pressure system making its way in from Siberia.

In Okinawa the winds also continue to remain strong out of the north, a classic cold surge for the island. Max wind gust even are expected to push well in to the Tropical storm strength type threshold on this sub-tropical island. It’s a cold wind though and today is most certainly not a day to head out and try to catch some waves as they could be up to 5 meters high along with a serious rip current.

 

Thing is for a lot of the low lying areas to get snowfall today it may not be sticking on the ground for long, there is a warm up expected heading to the weekend with above average temperatures across most of Japan, this means those areas that did see a little snow will likely have it melted off. Still though the record early season we have been seeing thus far will likely carry in to the winter season.

NORTH

Cold air has settled into the north region, with most locations seeing temperature ranges in the single digits and below zero, while other struggle to get into the teens. Lingering clouds will darken skies in eastern China, while high pressure builds in to the north and west, clearing skies and dropping temperatures.

CENTRAL

The newest Siberian surge has pushed through most of the central region, with the leading edge of the air mass moving along in a wide northeast to southwest arc from just offshore of the Ryukyu Islands, Taiwan, and southeastern China. Clouds and showers along the front and just behind will keep conditions damp and clammy as cooler air filters in during the day.

SOUTH

The south region has quieted own into a typical mid-autumn scenario, with lots of moisture over the southern half of the region, and slightly drier air filtering into northern locales on the heels of the seasonal northeast monsoon. High pressure continues to dominate the northern half of the Philippines, bringing clear to partly cloudy skies, while moisture remains to the west and south, helping stir up afternoon showers and thunderstorms over Indochina, Malaysia, Singapore, Brunei, northern Indonesia, and the southern Philippines.

With the exit of MEARI. We find only one weak disturbance to keep an eye on at the moment.

95W INVEST looks rather impressive on satellite photographs, with a distinct circulation point and flaring convection with a decent outflow. The system is very compact due to relatively dry air in the vicinity. VWS (Vertical Wind Shear) is moderate, in the 15-20 knot range, so development is not expected in the near-term. Computer models are not doing much with this system in the long-term, showing dissipation within the next 48 hours.

The remainder of the tropical locales will see a pretty good chance for afternoon showers and thunderstorms, with more widely scattered activity in the east.
