Next week, the whole country will usher in a wide range of rain and snow. What is a "cliff-jumping" drop in temperature?
Specific circumstances:
1. A new round of large-scale rain and snow is on the road in the central and eastern parts of Northeast China during the peak snowfall.
Affected by the eastward movement of the high-altitude trough, since last night, there has been an obvious snowfall in eastern and northeastern Inner Mongolia. Snowfall is expected to continue. Today, the daytime will be the period with the strongest precipitation. There is heavy snow and local snowstorm (10 ~ 16 mm) in parts of central and eastern Jilin and northeastern Liaoning. During this snowfall, the newly added snow depth in southern Heilongjiang, central and eastern Jilin, northern Liaoning and other places can reach more than 5 cm, and the local area 10 cm. The Central Meteorological Observatory issued a blizzard forecast at 06: 00 on February 19. The snowfall will not last long, and it is expected to come to an end on the night of 19, but it will have a great impact. The heavy snowfall on June 5438+09 in central and eastern Jilin and northeastern Liaoning may bring inconvenience to traffic. For example, some sections of Heda Expressway passing through northeastern Liaoning and eastern Jilin will encounter heavy snow; In addition, highways such as Suiman and Hunwu may also be adversely affected by snowfall and new snow.
Next Monday, with the southward movement of cold air and the strengthening of southerly warm and humid airflow, cold and warm air will jointly create a large-scale rain and snow process in the central and eastern regions for 20 ~ 22 days, and the southernmost boundary between rain and snow can reach Huanghuai and Jianghan. It is estimated that from June 5 to September 23, there will be small to medium snow or sleet in the eastern part of northwest China, north China, south-central part of northeast China, Huanghuai and western Jianghan, and there will be heavy snow or blizzard in some areas; There are small to moderate rains in Jianghuai, eastern Jianghan, Jiangnan, South China and the eastern part of Southwest China, and there are heavy rains in some areas.
The temperature rises in many places, such as warm spring. The temperature is now "jumping off a cliff" next week.
This weekend, China's central and eastern regions ushered in a warming climax, and temperatures in many places set new local records. For example, in Guangzhou, the highest temperature reached 29.2℃ on 16 yesterday, setting a new record in mid-February.
Today, the temperature in North China, the eastern part of Northwest China, Jiangnan and other places will generally reach high points, and the range of the highest temperature above 20℃ will be extended to Henan, Shandong and other places, the eastern part of Northwest China will also exceed 20℃, and the southern part of the Yangtze River will reach about 25℃. It is estimated that among provincial-level cities, Beijing, Xining, Jinan, Nanchang and other places are expected to break through this year's high temperature and generally reach the local "Yangchun March" temperature level.
It is estimated that from 08: 00 on 19 to 08: 00 on 2 1 9, the average or minimum temperature in northern Jiangnan, the middle and lower reaches of the Yangtze River and most of its northern areas will drop by 4 ~ 6℃, among which the cooling range in most northern Xinjiang, western Gansu, Ningxia, central Inner Mongolia, southern Northeast China, central and western North China, most of Huanghuai and Jianghan can reach 8 ~/kloc-. Most of the Bohai Sea and the Yellow Sea will have northerly winds of 7-8 grades and gusts of 9 grades. The Central Meteorological Observatory issued a gale cooling forecast at 06: 00 on February 19.
At the turn of winter and spring, the cold air is still very active, and the weather is often warm and cold at first, reminding everyone to pay attention to cold and warmth to avoid catching a cold.
