A must-see on your return trip! Most of the country is sunny and the temperature is rising, but the temperature difference between day and night exceeds 10℃, and there are heavy rains in Hainan.

China Weather Network News Tomorrow (October 7) is the last day of the National Day holiday, and many friends have already embarked on or are about to embark on the return journey. Generally speaking, most parts of the country will have sunny and good weather when returning from the National Day holiday, which is conducive to travel. However, precipitation is frequent in the southwest and Hainan Island has strong rain. Friends passing through these places need to pay more attention.

The weather is fine and the temperature is rising. The temperature difference between day and night is large.

At the beginning of this week, as the dry and cold air moved southward, the sky finally cleared up in many places in the south, but it also triggered a wave of record low temperatures in many places. As of 8 o'clock this morning, the lowest temperatures were 10.1°C in Hefei, 10.6°C in Nanjing, 10.9°C in Wuhan, 11.3°C in Guiyang, 11.6°C in Kunming, 12.2°C in Hangzhou, 12.9°C in Changsha, 15.4°C in Chengdu, 15.6°C in Shanghai, 16.5°C in Nanchang, 18.3°C in Guangzhou, 19.7°C in Nanning, and 23°C in Haikou, all hitting new lows since the beginning of autumn. Among them, Guangzhou and Nanning fell below 20℃ for the first time since the beginning of autumn.

It is expected that tomorrow morning, the temperature will continue to drop slightly in some parts of the south, and the lowest temperatures in Nanchang, Chongqing, Guiyang, Kunming, Lhasa, Fuzhou, and Nanning may hit new lows.

However, after this cold air passes, the temperature in the central and eastern parts will gradually rise. Today, some areas in the south have joined the ranks of rising temperatures. At 14:00, the temperature generally exceeds 25°C and feels comfortable.

However, due to widespread sunny weather in the south, the air has also become much drier. At 14:00, the relative humidity in many places in the middle and lower reaches of the Yangtze River was less than 30%, and the dryness was similar to that in the north.

It should be reminded that the minimum temperature rise is generally less than the maximum temperature, and the temperature difference between day and night is large. The temperature difference between day and night in most areas of the central and eastern regions is generally above 10℃, and you will feel cold in the morning and evening. Everyone should keep warm when leaving early and returning late on the way back, and it is a good idea to bring a jacket with you.

The day after tomorrow will enter the Cold Dew solar term. According to the current forecast, this year’s Cold Dew Festival has begun, and the average daily maximum temperature in most large cities in the south can reach over 25°C, which is very warm. Looking to the later period, the intensity of the cold air will be relatively weak before the 13th. Although there will be some temperature fluctuations caused by the weak cold air in the north, the overall temperature will still be close to the same period of the year or on the higher side.

Precipitation is frequent in the southwest and other places, with heavy rainfall in Hainan Island

Tomorrow and the day after tomorrow, most parts of the country will be behind the high-altitude trough, and the weather will be mainly fine and good, which is conducive to return travel. Rainfall will mainly occur in the western region and Hainan. Yunnan, Tibet, Xinjiang, Qinghai, Sichuan and other places will receive frequent rainfall, and there may also be snowfall in high-altitude areas. Friends passing through these areas should pay attention to slippery roads and low temperature weather.

In addition, rainfall in Hainan Island will also gradually increase. Due to the easterly return flow of cold air combined with terrain uplift, most areas of Hainan Island will experience heavy to heavy rains and local heavy rains tomorrow and the day after tomorrow.

Year-round, September to October is the period with the most rainfall in Hainan Island. Wanning has the most rainfall days in October. In the city, the rain in Tunchang and Wanning will become heavier tomorrow and tomorrow, and the heavy rain will turn to heavy rain on the 8th; heavy rain may also occur in Haikou on the night of the 8th. Affected by heavy rainfall, eastern Hainan is more likely to have flash floods and has a higher risk of geological disasters. Local friends and passengers returning via Hainan need to pay close attention to weather changes and arrange their itinerary reasonably.
