It was cloudy.
Inside it was still hot, and I wore no sleeve at work. However in the evening it became chilly.
I will go to Aomori on a business trip from tomorrow. It is located in the northern part of Japan. So the coldest temperature of the morning in Tokyo is equivalent to the hottest temperature in the afternoon there these days.
It would be around 16 degrees centigrade at day time.
I hope it is not so cold there.
