Good evening everyone.
This is my hobby cold-air observation diary
As I mentioned before, a strong cold air mass is expected to arrive around February 8. Its duration will be short — about one to one and a half days — but it will be very intense. Temperatures around 5,500 meters above Hokuriku are forecast to drop below −40°C, comparable to the recent heavy snow event.
If you’re heading to the ski resorts on February 8, please make sure you’re fully prepared and check the latest road and weather updates
Another cold air mass may briefly arrive around February 11, but it doesn’t look as strong.
