广东明起或现回南天！大部市县多云转阴，雨雾天气能见度低

Core Viewpoint - The weather forecast indicates a significant change in the low-level wind patterns in Guangdong and Guangxi, leading to a rise in dew point temperatures and the potential for a "return of the south" phenomenon, although it may not be very typical due to gradual surface temperature increases [1][4]. Group 1: Weather Forecast - On January 24, the weather in the southern Pearl River Delta and eastern Guangdong is expected to be mostly sunny to partly cloudy, with light fog in the mornings and evenings, and temperatures ranging from 2-5°C in northern Guangdong to 12-16°C in the Leizhou Peninsula [3]. - From January 25-26, most areas will transition from cloudy to overcast with light rain or fog, leading to lower visibility and rising temperatures [3][4]. - The specific forecast for Guangzhou on January 24 shows temperatures between 10-17°C, with a gradual increase to 10-22°C on January 25, and continued overcast conditions with light rain expected on subsequent days [4]. Group 2: Meteorological Analysis - According to meteorological analysts, the low-level winds will shift to a noticeable southerly direction on January 25-26, causing dew point temperatures to rise to 12-16°C, which may lead to moisture condensation and the "return of the south" phenomenon [1][4]. - However, the surface temperatures are also gradually increasing, which may prevent the phenomenon from being very pronounced [4].
