Hokkaido 3-month forecast The snow is likely to melt smoothly due to the warm winter trend

December 19, 2023 17:16

For the next three months, the winter-like atmospheric pressure distribution will be weak and less affected by cold air, so temperatures are expected to be higher than normal and snowfall on the Sea of ​​Japan side is expected to be at or below normal. Once the cold air hits, there is a possibility of snow falling in chunks, but it looks like the snow will melt smoothly. There will be another day of warning-level heavy snowfall in the second half of this week.

There is likely to be another warning-level heavy snowfall in the second half of this week.

From around the 21st (Thursday) to the 23rd (Saturday), strong cold air will flow into the Hokkaido area, intensifying the winter-like atmospheric pressure pattern. Depending on the degree of cold air and the strengthening of winter-like atmospheric pressure patterns, there is a risk of warning-level heavy snow and severe stormy weather, especially on the Sea of ​​Japan side. Last time, record-breaking snow fell mainly in the Rumoi region, but depending on the wind direction, the snow may become heavier in the Sapporo area as well.

Additionally, on the 25th (Monday), there will be snow all over the country due to the influence of a low pressure system moving north from the coast of Sanriku, and depending on the path of the low pressure system, there is a risk of heavy snow on the Pacific side and other areas.

Weather in January: Winter-like atmospheric pressure patterns are weak, but there are days with localized heavy snow.

Today, the 19th (Tuesday), the Sapporo Regional Meteorological Observatory announced the outlook for the next three months.

In January, precipitation will be near normal and temperatures will be near normal or above normal. As with normal years, there will be many cloudy and snowy days on the Sea of ​​Japan and Sea of ​​Okhotsk sides, and many sunny days on the Pacific side.

The Siberian high pressure system’s overhang near Japan will be weak. The winter-like atmospheric pressure pattern is generally weak and the inflow of cold air from the continent is expected to be weak, but there are some places where snow will fall due to the temporary inflow of cold air.

Weather in February Cold air advection from the continent is weaker than usual, and temperatures are at or above normal.

In February, precipitation is expected to be near normal, and temperatures are likely to be near or above normal. As in normal years, there will be many cloudy and snowy days on the Sea of ​​Japan side, but there will be many sunny days on the Pacific side, and there will also be many sunny days on the Sea of ​​Okhotsk side, as in normal years.

The Siberian High’s protrusion toward Japan is weak, and the winter-like pressure distribution is expected to be weak overall. As westerly winds meander northward near Japan, the inflow of cold air from the continent will also be weak.

Weather in March: The snow (long-term snowfall) is likely to end early.

In March, precipitation will continue to be at almost normal levels. Temperatures will be around normal or slightly higher. As in normal years, there will be many cloudy and snowy days on the Sea of ​​Japan side, but there will be many sunny days on the Pacific side, and it is expected that the Sea of ​​Okhotsk side will also have many sunny days, similar to normal years.

The Siberian High’s overhang near Japan will be weak, but the Aleutian Low will be stronger than normal. There will be days when we will have a winter-like atmospheric pressure pattern, but it will not last long and the inflow of cold air from the continent will be weak.

March is the season when snow melts in earnest. Temperatures are expected to be at or above normal, so the snow will melt smoothly and the snow (long-term snowfall) will end earlier than usual.
