Tomorrow, the 8th (Friday), a low pressure system that formed on the southern coast of the Kanto region will continue to develop and move northeast. Widespread rain and wet snow are expected to fall in the Kanto region from early morning until noon.
There is a possibility that sleet and wet snow will temporarily fall in the southern Kanto region, including central Tokyo, and a light layer of snow may accumulate on the roads.
A developing low pressure system passes over the southern coast of Kanto.
Today, the 7th (Thursday), northeast winds and north winds collide off the coast of Shizuoka Prefecture, creating band-shaped rain clouds called shear lines, which are causing rain mainly in Shizuoka Prefecture. A low pressure system is expected to form over the Shear Line late tonight as a pressure trough approaches.
This low pressure system is expected to develop and move northeast, bringing rain and wet snow to the Kanto region from early morning until around noon tomorrow.

Wet, sticky snow, the roads in Tokyo are barely white.
Kanto weather 8th (Friday)
At around 1,500 meters above the ground, cold air with temperatures below -3℃, which is the standard for snow on the Kanto Plain, will move south into the Kanto region, and snow is expected to fall temporarily in the southern Kanto region, including the city center.According to the current Weather News forecast, the rain that started in the early morning hours will turn into sleet and wet snow by morning, with around 2 cm of snow expected to fall around central Tokyo. However, due to the sticky, wet snow that contains a lot of water, it is expected that the road surface will only be slightly white.
Changes in rain and snow are affected by multiple factors, including trends in low pressure and cold air, and the intensity of precipitation, and are therefore accompanied by large uncertainties. If the temperature is lower than expected or the snow falls more heavily, the snow may last longer and the snowfall may be greater than initially expected.
It is thought that a difference in temperature of just 1°C or a slight difference in the way the rain falls can have a different impact. Forecasts may change at the last minute to reflect the latest information, so please check back regularly for the latest information.

Difficult predictions; predictions by various institutions are also different
At Weather News, in addition to our own forecast models, we also refer to forecast models released by the Japan Meteorological Agency and meteorological organizations around the world to compile our forecasts.
The above figure shows the predictions made by several prediction models at 6:00 am on Friday the 8th. The blue color indicates rain, the pink color indicates sleet or snow, and the darker the color, the more likely the rain or snow will be.
Looking at this map, there are many areas around the Kanto region where there is a boundary between rain and sleet/snow. However, there are differences in their forecasts, with some models predicting more snow, excluding coastal areas, and stronger forecasts in the north and west, while others predict more rain spreading around Tokyo, Kanagawa, and Saitama. there is. In addition, there are situations in which the range of rain and snow is forecast to be narrow, while others are forecast to be wide.
Additionally, as the intensity of the rain increases, the temperature tends to drop and snow tends to fall, but we can see that there are differences in the prediction of the intensity.
This rain and snow is caused by a low pressure system that develops soon after it occurs, so it is difficult to predict the location of the low pressure system, the timing at which it will start to develop, and the degree of development. There is a wide range of situations.
Possibility of snow in central Tokyo
Normally, as the timing of rain or snow approaches, the range of forecasts gradually becomes smaller and the accuracy becomes higher, but for this rain and snow, there is still a wide range of forecasts, and it is unclear whether it will be rain or snow. It is difficult to determine how much snow will fall.
According to the current Weather News forecast, there will be times when rain will mix with snow near central Tokyo. Even if it turns into snow, the snow quality is such that it is difficult to accumulate, so we believe that it is unlikely that there will be a solid snowfall. However, if the rain becomes more intense, the temperature will drop and there will be a risk of accumulation.
It is thought that a difference in temperature of just 1°C or a slight difference in the way the rain falls can have a different impact. Forecasts may change at the last minute depending on the latest information, so please check back regularly for the latest information.
