Rain clouds and snow clouds flow easily from the Sea of Japan side to the Pacific side, and there is a possibility of the first snowfall in Setouchi and Nagoya.
Especially around Nagoya, there may be a small amount of snow from tonight until tomorrow morning when the temperature drops. Be careful when driving as it is easy to slip due to freezing of the road surface or snow.
In automatic observation, the type of precipitation (rain, snow, cleft) when there is precipitation is determined from the observed values of temperature and humidity. It is based on the knowledge that the lower the humidity, the more likely it is to snow rather than rain, even at the same temperature.
According to the Meteorological Agency, there was a limit to continuous observation with conventional visual observation, but with automatic observation, continuous monitoring is possible 24 hours a day, so the time of the “first snowfall” isTendency to be faster… apparently … The mean value has been updated to the mean value for automatic observation.
