Over the next two days, the state of the atmosphere will become “very unstable”. Heavy rain accompanied by thunderstorms and gusty winds are also expected, mainly in the Hokuriku and Tohoku regions facing the Sea of Japan. In addition, the temperature drops sharply from the Sea of Japan side in contrast to the unseasonably warm weather. In the Kanto region, the southerly wind will strengthen during the day, causing a large amount of pollen to scatter, and it will become cold at night.
Today on the 1st, rain clouds are developing in places on the Sea of Japan side
On the 1st, there is a low pressure system with a front in the Sea of Japan, which is moving northeast.
A low pressure system and rain clouds associated with the front are covering the Chugoku region from Kyushu. Rain clouds are developing in some places, and in Kyushu, it rains locally at 10 mm or more per hour.
As the front moves southward, it will rain over a wide area of western Japan, the Hokuriku region, and the Tokai region on the evening of the 1st.
Tomorrow 2nd Atmospheric conditions are “very unstable” Beware of strong rain, lightning strikes and gusts
Today, the 1st was warm and sunny in various places, but the cold air is expected to move southward over the 2nd tomorrow.
At an altitude of about 5,500 meters, strong cold air of -30 degrees Celsius or less is expected to flow into Hokuriku and Tohoku, and even stronger cold air of -36 degrees Celsius or less is expected to flow into Hokkaido. As a result, the atmosphere will become “extremely unstable” mainly in Hokuriku and northern Japan, and thunderclouds will develop more easily.
Heavy rain and thunderstorms are expected from late at night on the 1st, mainly on the Sea of Japan side of the country. Snow will fall in the mountains and intensify locally. Please be aware of sudden changes in weather. San’in will also experience intermittent rain and thunderstorms.
Tomorrow 2nd, cold wind “temperature down” -10 ℃ compared to the previous day
Kyushu is expected to experience localized intensified rain and thunderstorms in Shikoku, Kinki, and Tokai until dawn on the 2nd tomorrow.
During the daytime on the 2nd tomorrow, the Pacific side is likely to recover from the weather in many places. However, the north wind will be cold even where the sun shines.
If you pay attention to the temperature, there are many places where it will be significantly lower than today, with Kanazawa being 10°C lower, and Osaka and Nagoya being more than 5°C lower. The maximum temperature in Tokyo will not change much from today, but the north wind will suddenly strengthen after the evening and it will be cold.
There are still few places where you can feel the cold in the morning, but assuming it will be cold at night, please choose a warmer coat than today before going out.

There are more places where cedar pollen is at its peak.
Cedar pollen will peak around early March in Kyushu, and around mid-March in Chugoku, Shikoku, and Tokai.
In the Kanto and southern Tohoku areas, the peak season is expected to continue through March.
This season is expected to be a “mass scattering”.
Not only people who have hay fever, but also people who have never had hay fever should take measures such as masks, hats, and glasses. After returning home, wash your face immediately, wash your hands and gargle, etc., so as not to bring pollen into your room.
