Cloudy skies in Kanto and Tohoku, spring weather in Western Japan... Cold weather returns to Hokkaido Tomorrow's weather

2025/01/20 18:55

Tomorrow, the 21st (Tuesday), clouds will spread across Kanto and Tohoku, making the weather gloomy.

On the other hand, Western Japan will be sunny and have spring weather.

The cold has returned to Hokkaido, and even in Sapporo, where the temperature rose to 5.4 C today, the expected maximum temperature tomorrow is 1 C.



Tomorrow, there will be high pressure in the west and low pressure in the east around Japan, and the isobars will be crowded on the Pacific side of northern Japan.
As a result, there will be snow in some areas of northern Tohoku.

Clouds are likely to spread in Kanto and Tohoku, which will be in a low pressure trough, and some areas will have rain in the afternoon.
Please be careful of changes in the weather.

On the other hand, many areas from Tokai to Okinawa, which will be covered by high pressure, are expected to be sunny and have spring weather.
In the Sanin region and other areas along the Sea of Japan coast, rain and snow will remain in some areas at first, but the weather will gradually improve.

The coldest "Daikan" of the year was as warm as April, with some places recording the highest January temperature ever recorded.

2025/01/20 16:12

From today, the 20th (Monday) to the beginning of February, it is the "Great Cold" on the calendar,
and is said to be the coldest time of the year,
but today the strong cold air above has passed,
and the country has become warmer, in anticipation of spring.



In Hokkaido and Tohoku, some places were as warm as April,
and some places recorded the highest temperature ever recorded in January.
In Nosappu, Nemuro City, Hokkaido,
the temperature was 8.3c,
as warm as the long holiday period in late April.

Compared to yesterday at 3:00 p.m., snowfall in Hokkaido has decreased by more than 10 cm,
and it is believed that the snow is melting rapidly.

Please be careful of avalanches and snow falling from roofs.

In addition, meltwater may freeze due to the cold overnight, causing the roads to freeze.

Please be careful of frozen roads from tonight to tomorrow morning.



The warm weather will continue to be much warmer than average until around Friday the 23rd.

On snowy mountains, large amounts of accumulated snow slide down, making full-depth avalanches more likely to occur, so please be careful.

Even though it is the 24th solar term "Daikan," the weather is as warm as March. There will be hotter than average days in the future, so be careful of snowmelt disasters.

2025/01/20 13:03

Today, the 20th (Monday), is the "Daikan" (Great Cold) of the 24 solar terms.
This is said to be the coldest time of the year, but it is not as cold as the calendar suggests and the cold is easing in many places.
Warm air is flowing in for this time of year, and many places will be as warm as March during the day.
Some areas on the Sea of Japan side are expected to see rain instead of snow.
In the Kanto region, rain will fall again in the evening due to the approach of a low-pressure trough in the upper atmosphere.
Please be careful of sudden heavy rain, falling snow, and gusts of wind.

The country is expected to be less affected by cold air from now on, and there will be many days with higher temperatures than average.
Some days will be significantly warmer than average in the Kinki region and west.



In areas where a lot of snow remains, the snow will melt rapidly.
In mountainous areas, when temperatures rise or after rain, "full-depth avalanches" are more likely to occur, in which all the snow on the mountain slides down.
Please avoid slopes where avalanches have occurred in the past, steep slopes, and signs that say "Watch out for falling rocks" or "Watch out for avalanches."
On roads with a lot of snow, caution is required as roads may become flooded after temperatures rise or rain.
In addition, snow is more likely to fall from roofs, so please ensure your safety by wearing a helmet when clearing snow from the eaves.

From tomorrow, the 21st (Tue) to the 23rd (Thu), high pressure will cover Japan, and many areas in Western Japan, Tokai, and Kanto will have sunshine.
Rain is expected in northern Kinki and Hokuriku.
In Tohoku, snow will likely fall on the 22nd (Wed), and rain will likely be the main event on the 23rd (Thu).
In Hokkaido, many areas on the Sea of Japan side will have sunshine tomorrow, the 21st (Tue). Snow will likely fall in some areas on the 22nd (Wed) and 23rd (Thu).





On Friday the 24th, a low pressure system is expected to pass near northern Japan.
Snow will fall in more areas on the Sea of Japan side of Tohoku, and snow will fall widely in Hokkaido, north of the low pressure system, including the Pacific side.

On Saturday the 25th, the low pressure system is expected to move east of Japan, resulting in a high pressure system in the west and a low pressure system in the east.
Snow will fall in some areas of Hokuriku, Tohoku, and Hokkaido.
The area where snow falls is expected to narrow on Sunday the 26th. On Monday, the 27th, a low pressure system will move eastward across the Sea of Japan, and a high pressure system will move east of Japan. Rain is expected in some areas, mainly in western Japan.

How long will the high temperatures continue in the cold Rain is expected to bring us back to mid-winter in the first half of next week [Weekly Weather]

2025/01/20 12:50

Today is the "Great Cold" according to the calendar, and the two weeks leading up to Setsubun are considered the coldest time of the year. However, this week, the country is expected to remain warm and not be affected by the cold. The highest temperatures are expected to continue from today, the 20th (Mon) to the 27th (Mon). (The areas circled in pink are 2 C or more higher than average.) Until around the 24th (Fri), many areas across the country will be 2 C or more higher than average, and as warm as March. In northern Japan and Hokuriku, where record-breaking snowfall is occurring, the snow will melt rapidly this week, increasing the risk of avalanches.
Please be careful of avalanches and snow falling from roofs, and be careful of accidents while removing snow.



However, this warm weather will not continue next week.

Around the 28th (Tuesday) next week, a low pressure system accompanied by a front is expected to move towards the southern coast of Honshu and Sakhalin, bringing rain across the country.

After this rain, the cold air that had been stagnating on the continent is expected to be released all at once, and strong cold air is expected to flow into the vicinity of Japan.



Looking at the forecast for the cold front on the night of the 29th (Wednesday),
cold air that would cause snow on the plains (below -6 C at around 1,500m above sea level)
is expected to completely cover the area around Honshu.

In Western Japan, it will be cold again with snow,
and-like cold will return.

The cold weather that is normal for this time of year is expected to return at the end of January.

This week will be a little warmer with a trend towards high temperatures, which will provide some relief,
but please be careful of the temperature changes from next week onwards.

At the start of the week, there is a risk of sudden rain and thunderstorms in the Kanto region at night. Temperatures remain high even in the coldest weather.

2025/01/20 06:04

Today, the 20th (Monday), a low pressure system is moving northeast over the sea east of Kanto. It is raining in parts of Kanto and Kinki. By morning, the rain will stop in many places, and the sun will return during the day.



However, in Kanto, there is a possibility of sudden rain and thunderstorms again after the evening. The rain will also spread to Hokuriku by the afternoon. Please bring an umbrella when going out.



This is the "Daikan" season of the 24 solar terms, but many places will see higher than average high temperatures today, with 12 C in Sendai and Tokyo, 13 C in Osaka and Hiroshima, and 16 C in Kochi and Kagoshima. Snow will melt in areas with heavy snowfall. Please be aware of worsening road conditions and falling snow.

Daikan, the coldest time of the year

2025/01/20 03:44

Starting from Monday, January 20th, it is Daikan, one of the 24 solar terms. It is the last of the 24 solar terms that divide the year into 24 equal parts, and is said to be the coldest time of the year.



The next solar term after Daikan is Risshun on February 3rd. The period of Daikan is from January 20th to Setsubun on February 2nd, the day before Risshun. The period before Daikan is Shokan, which is said to be the beginning of the severe cold, and is also called Kan no Iri.

In an old Japanese custom, rice cakes made with the coldest water during Daikan are called Kanmochi. It is said that eating Kanmochi will keep you healthy throughout the year.

"High temperatures despite cold weather" Tokyo sees earliest pollen dispersion in history; rain expected during tomorrow's (Monday) commute [Weekly Weather]

2025/01/19 12:58

Tomorrow, Monday, January 20th, is Daikan, one of the 24 divisions of the Japanese calendar.

It means the coldest time of the year, but contrary to the calendar,
the cold will ease up from now on, and the warm weather is expected to continue for a while, similar to that of March.



This week, the atmospheric pressure pattern is unlikely to be winter-like, and the effects of cold air will be minimal,
so that temperatures are expected to be high, much higher than average.

There is a possibility that the temperature will be high, a once-in-a-decade level, for this time of year.

In areas where a lot of snow remains, the snow will melt rapidly,
anding up the risk of avalanches.

There have also been many accidents while removing snow, so please be careful.


In addition, it was announced that cedar pollen began to fly in Tokyo on January 8th, one month earlier than usual.

The usual start of pollen dispersion is around early to mid-February,
This is the earliest start of pollen dispersion since statistics began in 1985.



As the warm weather continues this week, pollen may start to fly not only in Tokyo,
but also in Shizuoka Prefecture and other areas.

The warmer it is, the more pollen will fly,
so if you suffer from hay fever, take measures against it early.



Pollen dispersion decreases when it rains,
but when and where will it rain in the future



A low pressure system is expected to form off the coast of Tokai by tonight.
Moist air is expected to flow in, and the atmospheric conditions are expected to become unstable, mainly in the Kanto region.

From tonight to tomorrow morning during the commute to school,
rain is likely to fall in some areas, mainly in the Kanto and Tokai regions.
Please also be careful of lightning and gusts of wind.

The weather on the Pacific side will improve around noon tomorrow, Monday the 20th,
However, in the afternoon, there will be rain and snow in some areas on the Sea of Japan side of Sanin and Tohoku.

Snow and rain will intensify on the Sea of Japan side from around Thursday the 23rd to Saturday the 25th,
Rain and snow are not expected to intensify until Wednesday the 22nd. However, next week, the season will reverse and it will likely snow in some areas of western Japan. It looks like we won't be able to enter spring with this warm weather.
