[About the weather for this period]
#Characteristics of atmospheric pressure distribution
On the 28th, the area around Honshu was within a high pressure zone. The extratropical cyclone that changed from Typhoon No. 7 moved away from Japan to the east and merged with the front. The rainy season front is stationary from the East China Sea to the south of Honshu and the sea east of Japan. On the 29th, the area around Honshu will be gently covered by high pressure over the Sea of Japan and the sea east of Japan. The rainy season front extends from South China to the East China Sea and the southern coast of Honshu, and is gradually moving north. On the 30th, there was a high pressure area near Honshu. The rainy season front passed from southern Japan to southern Kyushu and extended into central China. On the 1st, the rainy season front remained stationary near Honshu. There are kinks on the front to the east of Japan and the East China Sea, and the kinks on the front turned into a low pressure system around 9 a.m. and moved east-northeast. On the 2nd, the rainy season front stalled near Honshu, and the low pressure above the front moved eastward from near the San'in area to the south coast of the Kanto region. Typhoon No. 9 occurs in the Marshall Islands. On the 3rd, the rainy season front passed through southern Kyushu and stopped south of Honshu. On the 4th, the rainy season front remained stationary from the Tsushima coast to western Japan and southern Japan. Typhoon No. 9 was extremely powerful and moved westward near the Truk Islands, accompanied by strong winds.

#Precipitation
On the 28th, the effects of warm, humid air associated with the typhoon and the seasonal rain front remained, and rain began to fall on and off in western and eastern Japan.

On the 2nd, a linear precipitation band formed in five prefectures in northern Kyushu (Fukuoka, Saga, Nagasaki, Oita, and Kumamoto) due to low pressure above the front and warm, humid air flowing toward the front. On the 3rd, atmospheric conditions became unstable mainly along the mountains of northern and eastern Japan, and there were places where it rained. On the 4th, a kink occurred on the front. Heavy rain fell near the front and kink. In Kyushu, rain fell mainly in Kumamoto and Saga prefectures due to the influence of the rainy season front.

Today is Tanabata. What's the weather like tonight Let's look for "Orihime Star", "Hiko Star", and "Milky Way"

2026/07/07 11:42

#Let's look for ``Orihime Star'', ``Hiko Star'', and ``Milky Way''
Today, July 7th (Tuesday), just after 9:00 p.m., if you look up at the eastern sky, you will see the ``Summer Triangle.''
The three stars of the ``Summer Triangle'' are extremely bright ``1st magnitude stars'' among all the stars.



Among these three stars, two particularly bright stars are "Orihime Star" and "Hikoboshi".
The bright star that rises first and can be seen from a high place and is to the north is "Orihime Star".
Orihime star is called Vega in the constellation Lyra in the West, and Hikoboshi is called Altair in the constellation Aquila.
In addition to Orihime Star and Hiko Star, another bright star is Deneb in the Cygnus constellation.
Also, where the air is clear and there are no city lights, you can enjoy the Milky Way.
The Milky Way flows from Deneb through the Summer Triangle and between Vega and Altair.

#What's the weather on Tanabata night
Today, July 7th (Tuesday) at 9pm, Okinawa will be covered by a Pacific anticyclone, and the night will be clear, so Orihime, Hikoboshi, and the Milky Way will be visible in many places.
The seasonal rain front is expected to slowly move south over the southern coast of Honshu, but western Japan will be covered in clouds due to the moist air, and there will be some showers.
On the East China Sea side of Kyushu, there seems to be a chance to peek at the starry sky of Tanabata through the gaps in the clouds.



Parts of the Tokai region will also be sunny, so you can enjoy the starry sky of Tanabata, but there will be showers along the mountains.
There are a lot of clouds in the Kanto region, and the sky is likely to be unlucky for observation.
The Sea of Japan side of Hokuriku and Tohoku, and near the Oshima Peninsula in Hokkaido, there are places where you can see Orihime Star, Hikoboshi, and the Milky Way.

#The 25th is a new moon; the influence of moonlight is small, making it easier to see the Milky Way.
The Stars of Tanabata can be seen past July 7th and into August.
This year, there will be a new moon on July 25th (Saturday), so the influence of moonlight will be less during the new moon, making it easier to see the Milky Way.
