[Kyushu: Widespread rain this weekend] When will the rain start? When will it stop? (Analysis by weather forecaster Junko Miyake)

2026/11/13 14:36

"The weather in the Kyushu region is gradually taking a turn for the worse.



Let's start by looking at the current cloud cover.
While clouds have spread across the Kyushu region, they are not particularly thick, and in some places, sunlight is still filtering through the gaps.

However, looking toward the west, there is a large mass of clouds-associated with a weather front and an area of ??low pressure.



By tomorrow (Saturday), this low-pressure system and front will approach the Kyushu region.
Then, on the 15th (Sunday), a low-pressure system along the front is expected to intensify slightly as it passes near the main island of Honshu.

Across the Kyushu region, rain will become widespread from tomorrow afternoon through the 15th (Sunday), with some areas likely to experience steady, heavier rainfall.



Now, let's take a look at the forecast for rain and wind.

By tomorrow morning, rain may begin in parts of northern Kyushu.
Around midday, rain clouds will also move over southern Kyushu.
As the day progresses into the evening, rain is expected to spread across a wide area.



While there will be few places in the Kyushu region experiencing heavy rain through tomorrow,
by the day after tomorrow, Sunday the 15th,
the rain will intensify in parts of southern Kyushu.
In areas around Kagoshima and Miyazaki prefectures in particular,
there is a risk of heavy rain accompanied by thunderstorms.

If you are heading out on Sunday, please bring a large, sturdy umbrella.


Conditions will likely remain favorable for rain through around midday on the 15th.
By evening, however, the rain should taper off across almost the entire Kyushu region.



Now, let's take a look at the weather for each area.
Here is the forecast for today, Friday.

Across the Kyushu region, cloudy conditions will persist.
Temperatures will be quite high-comparable to what is typical for October.
In Naze, the temperature is expected to reach 26C, making it a "summer day" (a day with a high of 25C or above).
Late tonight, rain may begin to fall in places like Fukue, in the Goto Islands.



Here is the forecast for tomorrow, Saturday.
Rain will be widespread; it is expected to begin in the morning across northern Kyushu,
and in the afternoon across southern Kyushu.
Despite the rain, temperatures will remain high-for instance, Fukuoka is expected to reach 20C.



Here is the weekly forecast.
Rain will continue into Sunday, the 15th.
Expect widespread rain until around midday.
Although skies will clear temporarily on Monday, the 16th,
another low-pressure system will approach between Tuesday, the 17th, and Wednesday, the 18th, bringing rain to a wide area.
As this low-pressure system is expected to develop rapidly,
there is a risk of intensifying rain and wind, particularly around Wednesday, the 18th.
Conditions may become severe, potentially causing disruptions to transportation,
so please be sure to stay updated with the latest information.

[Risk of Severe Weather] Strong cold air moving south by the middle of next week may bring severe weather nationwide; the Kanto region should also prepare for high winds.

2026/11/13 14:17

Be prepared for stormy weather across the country around the middle of next week.





A low-pressure system is expected to form near the northeastern part of the Chinese mainland on the 17th. As it moves across the Sea of ??Japan, it is projected to intensify, reaching a central pressure of 958 hPa by Thursday, the 19th.
Consequently, a strong "west-high, east-low" pressure pattern?characterized by high pressure to the west and low pressure to the east?will develop around Japan by the 19th. The isobars will become very tightly packed, leading to strong northerly winds across the entire country.





On the 19th, a cold air mass of -30C at an altitude of approximately 5,000 meters is expected to push as far south as the southern part of Hokkaido.
Additionally, a cold air mass of -6C at an altitude of 1,500 meters?a threshold typically associated with snow reaching low-lying areas?is forecast to move south from Hokkaido into the northern Tohoku region.
As a result, Hokkaido and the Tohoku region will likely see snow, accompanied by strong winds exceeding 15 m/s. There is also a risk of blizzards, particularly along the Sea of ??Japan coast. In parts of western Japan?including the Chugoku and Kinki regions?snow may fall at higher elevations.
Additionally, in areas along the Pacific coast, such as the Kanto and Tokai regions, there is a risk of strong winds exceeding 15 m/s.

Please note that these forecasts may change depending on how the low-pressure system develops; therefore, be sure to check for the latest information regularly.

[Rain across a wide area on Sunday the 15th] Widespread rough weather expected by the middle of next week; potential impact on transportation (Analysis by weather forecaster Junko Miyake)

2026/11/13 14:15

"Most areas will remain sunny through today (Friday),
but the weather will take a turn for the worse starting tomorrow (Saturday), with rain expected across a wide area by the 15th (Sunday).



Let's begin by looking at the current cloud cover.
Much of the Honshu region is clear.
However, clouds have spread over the Sea of ??Japan side of the Tohoku region and around the Izu Islands,
where some areas are experiencing rain and thunderstorms.

Please be cautious of sudden heavy downpours, lightning strikes, and strong gusts of wind through late tonight.
Looking toward the west, you can see a large mass of clouds-
these are associated with a low-pressure system and a front.



Looking at the forecast weather map for tomorrow (Saturday) evening,
a low-pressure system and a front will be approaching from the west.

By the 15th (Sunday), a low-pressure system along this front is expected to intensify slightly as it moves across the Honshu region.
Due to this system and the front, rain is expected to become widespread on the 15th (Sunday).

Many people may be celebrating 'Shichi-Go-San' on November 15th;
if you are heading out, please be sure to take precautions against the rain to keep your formal attire from getting wet.

" />

Let's take a look at the forecast for rain and wind, starting from tomorrow evening (Saturday).

Tomorrow, rain will begin in the west-starting in areas like Kyushu-and by nightfall, it will likely be raining across much of western Japan.

As we move into the 15th (Sunday), rain is also expected to begin in many parts of the Tokai and Hokuriku regions.



By noon on Sunday, rain clouds will spread across the Kanto region, and rain is also likely to begin in parts of the Tohoku region.

In areas along the Pacific coast, the rain may intensify at times.

By Sunday afternoon, the rain will likely begin to taper off in the west, including in Kyushu; however, rain is expected to persist in parts of the Kinki and Kanto regions, as well as in the Tohoku and Hokkaido regions.




After the low-pressure system passes this Sunday,
a "winter-type" pressure pattern will temporarily set in.

Following this, another low-pressure system and its associated fronts will approach from the west.
This next system is expected to intensify rapidly as it nears the main island of Honshu.
A cold front extending from this system will also sweep across Honshu,
likely bringing widespread rain and strengthening winds.

There is a risk of stormy weather, particularly around Wednesday the 18th.
Additionally, as cold air moves in at higher altitudes on Thursday the 19th,
snow and strong winds are expected in northern Japan.
Some areas may even experience a "winter storm,"
so please be prepared for rough weather around the middle of next week.



Now, let's look at the detailed weather for each region.
For the rest of today (Friday), many areas will remain clear.
Daytime temperatures will be quite high-comparable to those typically seen in October.
Even in northern Japan, many places will see temperatures exceed 15C,
making for a pleasantly mild day.



Here is the forecast for tomorrow (Saturday).
Rain will begin to spread from the west.
Even in the Kinki and Shikoku regions-where rain is not explicitly indicated in the forecast-
some areas may see rain late in the night.

Meanwhile, in regions from Tokai northward,
sunny intervals are expected to persist, keeping conditions mild and comfortable.

Here is the weekly forecast.
On Sunday the 15th, rain will fall over a wide area.
On Monday the 16th, some places in Northern Japan and the Hokuriku region may see rain or snow.
On Tuesday the 17th, a front will approach from the west, bringing rain to many areas.
In Tokyo, temperatures will remain low, and the rain is expected to be cold.
Then, around Wednesday the 18th, rain and wind will intensify across a broad region.
Depending on how much the low-pressure system develops, there is a possibility that transportation services could be affected.
Please stay updated with the latest weather information.

Weather for the afternoon of Friday, the 13th: Rain in the Tohoku region will gradually taper off; be alert for thunderstorms in the Izu Islands through tomorrow.

2026/11/13 12:40

A low-pressure system with an associated front is moving east-northeast over the Sea of Okhotsk, while another low-pressure system is moving eastward off the Kii Peninsula.
Meanwhile, high-pressure centers are located east of Japan and near the Tsushima Strait, both moving in an easterly direction.




Currently, due to cold air in the upper atmosphere and a trough, developed rain clouds are affecting parts of Akita and Iwate Prefectures. Additionally, rain is falling in the Izu Islands, where warm, moist air is flowing in from the sea to the south.

This afternoon, Friday the 13th, some areas in the Tohoku region will continue to see developed rain clouds; however, the rain is expected to gradually taper off by evening, with conditions improving thereafter. In the Hokuriku region, rain may occur in some places, but it is likely to end by around evening.
Conversely, in the Izu Islands-particularly in the southern part-rain is expected to persist through tomorrow, Saturday the 14th. Please be cautious of lightning, sudden gusts of wind, and brief, heavy downpours.



In other regions, sunshine is expected.

From tomorrow, Saturday the 14th, a low-pressure system and a front will approach from the west, causing weather conditions to deteriorate, starting in Western Japan. For those in Western Japan, it is advisable to complete tasks such as hanging laundry outside, running errands, or attending to agricultural work today. In Eastern Japan, rain is expected to become widespread by the day after tomorrow, Sunday the 15th, so be sure to make the most of the sunshine available through tomorrow.

Friday, the 13th: Beware of thunderstorms and gusty winds in the Hokuriku region; Kanto-Koshin to see fair, calm weather.

2026/11/13 06:53

A low-pressure system with an associated front is located near Sakhalin and is moving eastward.
The area around Honshu is covered by a broad, band-like high-pressure system, with centers located southeast of the Kanto region and near the Tsushima Strait.
A small low-pressure system is situated south of the Kii Peninsula and is moving slowly toward the east.



Currently, there is a band of precipitation across Akita, Yamagata, and Iwate prefectures, with some areas experiencing rain accompanied by thunderstorms.
Additionally, due to the small low-pressure system, there is localized rain occurring on the Kii Peninsula.



Today, the Kanto-Koshin region will be generally clear, with no expected deterioration in the weather. Temperatures will rise during the day, leading to pleasant, comfortable conditions.



While the rain clouds near the Kii Peninsula are expected to gradually move away toward the southeast, those in the Hokuriku region should remain cautious of lightning, sudden gusts, and brief, heavy downpours through around midday.

/>

The weather will begin to deteriorate from the west tomorrow, and by Sunday the 15th, rain is expected across a wide area.



From Tuesday the 17th through Thursday the 19th, a developing low-pressure system will bring rain to a large portion of the Honshu region. Winds may strengthen as this system passes through.
Please stay updated with the latest information.

Rain expected across a wide area this weekend; unsettled weather likely to continue into next week.

2026/11/12 19:10

The area around Japan is covered by a broad, belt-like expanse of high pressure, with centers located south of the Kanto region and over the East China Sea.




Currently, rain or snow is falling in parts of Hokkaido, Yamagata Prefecture, and Niigata Prefecture. The Kanto-Koshin region is generally clear, while clouds have spread across Western Japan.

Tonight, the weather in the Kanto-Koshin region is expected to remain stable. In Northern and Western Japan, however, clouds will spread, and there may be scattered showers in Hokkaido, along the Sea of ??Japan side of the Tohoku region, and in the Chugoku and Shikoku regions.

Tomorrow, the area around Honshu will remain under the influence of high pressure, leading to mostly calm, clear weather during the day. On the other hand, along the Sea of ??Japan side of the Tohoku region and in the Tokai region, there is a risk of intermittent rain or thunderstorms, particularly during the morning hours.





On Saturday, the weather will begin to deteriorate from the west, and by Sunday the 15th, rain is expected to spread across a wide area. Furthermore, from Tuesday to Thursday of the following week, the passage of a low-pressure system may bring rain to a large portion of the area around Honshu.

[One-Month Forecast] Temperatures are expected to be higher than average across eastern and western Japan as the region remains prone to being covered by warm air; conditions are also likely to be influenced by low-pressure systems and fronts.

2026/11/12 17:54

The Japan Meteorological Agency (JMA) released its one-month forecast today, Thursday the 12th, covering the period from November 14 to December 13.

Over the next month, the entire country is likely to be covered by warm air, with temperatures expected to be higher than average, particularly across eastern and western Japan.
Additionally, as the country will be prone to the influence of low-pressure systems and fronts-especially during the early part of this period-precipitation is expected to be above average along the Pacific coast of northern Japan and the Sea of Japan coast of eastern Japan. Along the Sea of Japan coasts of northern and western Japan, precipitation will likely be near or above average.



Regarding the one-month average sea-level pressure (left chart), higher-than-normal pressure is expected south of Okinawa, while a trough (an area of ??low pressure) is forecast to extend from the Sea of Japan toward Hokkaido. The entire country is likely to be affected by low-pressure systems and fronts, particularly during the beginning of the period.

Temperatures at an altitude of approximately 1,500 meters (right chart) are expected to be higher than average, especially over eastern Japan, as the region is likely to be covered by warm air. Conversely, a slight negative deviation is indicated for the Sea of Okhotsk, while in western Japan, Okinawa, and the Amami region, temperatures will remain close to the seasonal average, with the possibility of occasional influence from cold air.



alt=""Image"" width=""500"" height=""281"" /> This forecast covers the expected average temperatures, precipitation, and sunshine duration for the next month, along with weekly average temperature projections (including the probability of occurrence in %).

As the country is likely to be covered by warm air, temperatures over the next month are expected to be above average in Eastern and Western Japan, and near or above average in Northern Japan, Okinawa, and the Amami region.

Due to the anticipated influence of low-pressure systems and fronts-particularly early in the period-precipitation over the next month is expected to be above average along the Pacific coast of Northern Japan and the Sea of Japan side of Eastern Japan. Across the Sea of Japan side of Northern to Western Japan, precipitation is likely to be near or above average. On the Sea of Japan side of Eastern Japan, more cloudy or rainy days than usual are expected.

Sunshine duration over the next month is expected to be below average along the Pacific coast of Northern Japan, and near or below average along the Pacific coast of Eastern to Western Japan. Fewer sunny days than usual are anticipated along the Pacific coast of Northern and Eastern Japan. In Western Japan (Pacific side), while the weather will shift in a cycle every few days, there will likely be fewer sunny days compared to a typical year.

This past week, many areas-especially in Northern Japan-experienced temperatures below average due to the influence of a strong cold air mass. Looking ahead, however, there will be days where temperatures rise above average, particularly across Eastern and Western Japan. That said, cold air may still occasionally push southward, causing temperatures to drop; please adjust your clothing accordingly to stay healthy amidst these temperature fluctuations.

Furthermore, the region is expected to be susceptible to the influence of low-pressure systems and fronts, especially early in the period. Around the 18th-19th, a low-pressure system is forecast to develop rapidly as it moves across the Sea of Japan, which may lead to stronger rain and wind. In Northern Japan, snowfall could also reduce visibility in some areas. Please check the latest weather forecast daily.

Weather forecast for the Chugoku region: Sunshine is expected until tomorrow, the 13th, but the weather will deteriorate from the 14th onwards.

2026/11/12 16:40

"Here is the weather forecast for the Chugoku region.
Today, the area around Japan is under the influence of a high-pressure system.



The Chugoku region has been mostly clear, with plenty of sunshine. There is no risk of rain tonight.



Tomorrow, while some areas may see clouds in the morning, the day is expected to be generally clear. High temperatures will exceed 20C in many places-warmer than the seasonal average.



Looking ahead, a front will approach from the west on Saturday the 14th, leading to a deterioration in the weather. Rain may begin in some areas by the afternoon, and widespread rain is expected on Sunday the 15th.

" />

On Monday the 16th, a winter-type pressure pattern will develop, bringing rain to areas along the Sea of Japan coast.
From Tuesday the 17th through Wednesday the 18th, a low-pressure system accompanied by a front is expected to move across the Sea of Japan while intensifying rapidly, leading to widespread rain once again. Winds will also strengthen, likely resulting in driving, slanted rain. As the front passes, there is a possibility of heavy rain or thunderstorms, so please be sure to check for the latest updates.
On Thursday the 19th, a winter-type pressure pattern will return, bringing rain to the Sea of Japan side of the region. Temperatures are expected to drop significantly, so you will likely need a warm outer layer.
That concludes the weather forecast for the Chugoku region.

Weather for this weekend: Conditions to deteriorate from the west, with rain expected across a wide area on Sunday.

2026/11/12 14:06

This coming weekend, from Saturday the 14th to Sunday the 15th, a weather front and a low-pressure system will approach from the west, causing conditions to deteriorate, starting in Western Japan. If you are planning any outings, Saturday is the better choice.



Today, Thursday the 12th, much of Japan is under the influence of a high-pressure system, resulting in clear skies across many areas. Tomorrow, Friday the 13th, while clouds may develop in some places, the high-pressure system will persist, keeping skies mostly clear.
Looking ahead to the weekend, a weather front and a low-pressure system are expected to approach, leading to a decline in weather conditions, beginning in Western Japan.

On Saturday the 14th, a low-pressure system is expected to form along a front and move eastward. By the afternoon, rain will likely begin to fall in Kyushu, Okinawa, and the Chugoku region.
On Sunday the 15th, the low-pressure system is forecast to travel across the Sea of Japan and pass near Northern Japan. A cold front extending from this system will sweep across much of Honshu, bringing rain to a wide area stretching from the Tohoku region down to Okinawa. Hokkaido is also expected to see an increase in cloud cover.


As a weather front and an area of low pressure pass through, rainfall may intensify in some places. Winds are also likely to pick up, especially along the coast, so you will probably need a sturdy umbrella.
Additionally, warm, moist air will flow toward the front and the low-pressure system, making atmospheric conditions unstable-particularly across the Okinawa and Kyushu regions. Please be on the lookout for lightning, sudden gusts of wind, and intense, short-lived downpours.





Daily high temperatures are expected to be around or above the seasonal average. Even though clouds may spread across the sky, warm air brought in by southerly winds will keep temperatures on the higher side.
Expect highs of around 10C in Hokkaido, over 15C in many parts of the Tohoku region, and around 20C across the Hokuriku, Kanto, and western Japan regions.
Be sure to adjust your clothing appropriately to avoid falling ill due to temperature fluctuations.

From Calm Sunshine to a Dramatic Change: Weekend Rain and Stronger Rain and Winds Expected by Midweek Next Week (Weather Commentary by Meteorologist Junko Miyake)

2026/11/12 13:39

eather conditions will remain sunny through Friday, but rain is expected to spread from the west over the weekend.

First, let's take a look at the current weather distribution.

As of 11:00 a.m. today, many areas across western and eastern Japan, as well as the Pacific side of northern Japan, are enjoying clear skies.

Some rain is falling along the Sea of Japan side of northern Japan, but it is generally light, with rainfall amounts of around 1 to 2 millimeters per hour.

High pressure will continue to cover the region through tonight, bringing mostly sunny weather to much of Honshu.

This high-pressure system extends across the continent, forming an elongated ridge of high pressure.

Sunny conditions are expected to continue across much of Japan through Friday.

However, weather conditions will begin to deteriorate from the west starting Saturday.

A front and low-pressure system will approach from the continent, and rain is expected to gradually begin across Kyushu during Saturday afternoon.

The system will then strengthen somewhat as it moves across Japan with its associated front.

As a result, widespread rain is expected on Sunday, November 15.

Around Tuesday, November 17, a similar pressure pattern to that of Saturday, November 14, is expected to develop, with another front and low-pressure system approaching from the west.

However, the low-pressure system expected next week is forecast to intensify rapidly near Honshu.

Compared to the system affecting Japan this weekend, next week's low is expected to be stronger and may bring heavier rain and stronger winds nationwide.

Please pay close attention to forecasts for rain and wind next week.

Detailed forecasts for each region follow.

For the rest of today, Thursday, sunny weather will continue in many areas.

Temperatures will rise to around 20C during the day, bringing mild and pleasant autumn conditions.

On Friday, although there will be some clouds, generally sunny weather is expected to continue.

Temperatures will rise even higher than today, and from the Kanto region westward, it may be comfortable enough to spend the daytime outdoors wearing just a long-sleeved shirt.

Now for the weekly outlook.

On Saturday, November 14, rain will gradually begin across Kyushu.

As the day progresses, the area of rain will steadily expand eastward.

By Sunday, November 15, widespread rain is expected from Kyushu to the Tohoku region.

Warm southerly winds will accompany the system, meaning that even in Tohoku, precipitation is expected to fall mainly as rain rather than snow.

On Monday, November 16, colder air will move in, and snow is expected in Sapporo.

Wednesday, November 18, a developing low-pressure system may bring stronger rain and winds across the country.

Please continue to monitor the latest weather information.
