Kanto Snow is expected in Tokyo on the 23rd, next week is extremely cold, the maximum temperature is around 0 ° C in the center of the inland (weather forecaster Akiko Aoyama January 18, 2023)-Japan Weather Association tenki.jp

The weather in the Kanto region changes greatly depending on the course of the “Southern Coast Low Pressure” that advances along the southern coast. There are 3 patterns.

① If the south coast low pressure moves north of Hachijojima, the Kanto area will be covered by the low pressure precipitation area and warm air will flow in. Therefore, what falls is likely to be rain, not snow.

(2) If the south coast cyclone moves a little south of Hachijojima, it will draw in cold air from the north while rainfall will cover the Kanto region. Therefore, it snows easily, and sometimes it snows heavily.

(3) If the south coast cyclone moves south of Hachijojima, the precipitation area itself will not reach the land of Kanto, and snow and rain will not fall in many cases. However, as cold air moves southward, clouds tend to spread in the Kanto region.

The path of the south coast cyclone and the location of Hachijojima are one of the criteria for forecasting snow in the Kanto region, but this is not the only decisive factor. Whether or not there will be heavy snowfall in the Kanto region depends on factors such as the degree of development of the cyclone, the speed at which it advances, the drop in temperature, and the influx of moist air. (Even if it’s raining like ①, if it rains harder, the surrounding air will cool down and turn into snow.) People in the Kanto region are usually not used to snow, solatest weather forecastIf snow is expected, please take precautions as soon as possible.
