Weather will be unstable on Wednesday, head of the Egyptian Meteorological Authority Ahmed Abdel Aal said during a phone interview Monday evening on al-Hayat channel.
Rain clouds are expected and a drop in weather temperature, he added.
The maximum and minimum temperatures predicted Wednesday in Cairo are 16/8 C, according to Abdel Aal.
Abdel Aal said heavy mist over the past two days was caused by the evaporation of rain water in the air.
