Did it hail in Xiangfan, Hubei Province on the evening of July 30, 2011?

At about 2:30 pm on July 25, 2011, heavy rain and hail fell in Group 4 of Duwan Village, Taipingdian Town, Fancheng District.

At 3 pm on July 25, the Xiangfan Meteorological Observatory issued three warning signals for thunder, strong winds, and heavy rain: Affected by strong convection, there will be thunderstorms and hail in the next three hours, with local precipitation of 20 to 50 mm. It will be accompanied by strong winds of magnitude 7 to 9.

At about 4 o'clock in the afternoon, there was heavy wind and rain, lightning and thunder, and dark clouds rolled over the city. According to statistics from the Municipal Meteorological Department, as of 6 p.m., rainfall in the urban area was 48.5 millimeters, with Cihe in Gucheng receiving the highest rainfall at 97 millimeters. Rain brings relief, but it also brings disaster. Cool down by 12°C within 3 hours. At 2 pm, the temperature was still 35°C, and by 5 pm, the temperature dropped to 23°C.

Yang Furong, deputy director of the Municipal Meteorological Observatory, said that the weather convection was relatively severe this time. Due to the greater intersection of warm and cold air at the edges, hail and severe weather occurred. According to radar monitoring, hail occurred in Xiangzhou District, northern Baokang, and southern Gucheng, and soft hail and small hail also occurred in the northern part of Nanzhang.

It was still unbearably hot in the morning, so why did it suddenly rain and hail in the afternoon? Yang Furong explained that during this period, the warm and humid air currents in the southwest are particularly active, the sun is shining brightly, and the temperature rises very quickly. But this creates a situation where the ground temperature is high and the air temperature is low. The collision of warm and cold air currents can easily form strong convective weather, especially thunderstorms in the afternoon. At the same time, it also creates conditions for the formation of hail.
