Weekly weather National cold Until around Wednesday Snow and blizzards in Hokkaido
Cold air has entered the vicinity of Japan since last night, and it is snowing mainly on the side of the Sea of Japan in Hokkaido, and the first snow in the northern part of Tohoku. The cold air is expected to remain until around Wednesday.
Tomorrow, Hokkaido will be covered with snow and the plains of Tohoku will be covered with snow and ice, and the air will be cold even in sunny places.
From last night until this morning, the cold winds nationwide intensified and the temperature dropped dramatically. Hokkaido gradually changed from rain to snow, and the first snowfall was observed in Aomori and Morioka. The cold air intake will continue for a while.
On Tuesday morning 10, cold air below -6 degrees Celsius will cover the northern part of Tohoku about 1500 meters above the ground, which is a guideline for “snow on flat ground”. Cold air below 0 degrees Celsius is expected to flow towards the southern coast of Honshu about 1,500 m above the ground, which is a guideline for “snow in the mountains”.
Hokkaido is snowed mainly on the Sea of Japan side, and there is a risk of snow accumulating in the city. Even in areas that are used to snow, the feeling of driving on snowy roads does not return at the beginning of the season and accidents are more likely to occur. Also, there may be places where the wind blows a little stronger and the visibility worsens. Maintain sufficient distance between vehicles, avoid braking and sharp turns, and drive carefully.
Cold rain and snow in the northern part of Tohoku. Even on flat terrain, inland snow can accumulate and the road surface can freeze.
It can snow along the mountains from southern Tohoku and Hokuriku to northeast Kan, as well as along the Nagano and Gifu Mountains. Cars passing through the pass require winter gear. In addition, there is a possibility that snow clouds will cover high-altitude areas in the north of Kinki and the Chugoku region, and there are likely to be mountains that will become the “first snow”.
The plains, Shikoku and Kyushu, from the Kanto region to the Chugoku region, are very sunny, but the temperature is usually around 15 degrees Celsius during the day and it will be cold even in the sunlight. It would be nice to have a slightly thicker coat than before. It’s cloudy and rainy in Okinawa, and it’s cold too.
The weather and temperature beyond that
The influence of cold air will continue on the 11th (Wednesday). Hokkaido and Tohoku will have snow and rain mainly in the morning, and there will be cold rain and snow around Hokuriku. The temperature doesn’t rise as much from sunny Kanto to the west, and the cold continues.
On the 12th (Thursday), the area around Japan will be covered with high pressure and the cold air will gradually disappear. Snow and rain will cease and is expected to disappear across the country. The wind will be relatively calm. However, radiant cooling will be enhanced by that amount and the morning temperature will drop dramatically. There will be many places that will be the coldest so far this season.
After the 13th (Friday), warm air from the south will come in. The temperature will be slightly higher than normal. Hokkaido and Tohoku are often affected by low pressure and front lines, but it will likely rain rather than snow.
