Experts of the Egyptian Meteorological Authority (EMA) forecast that nice weather to prevail in most parts of Egypt on Saturday. The same weather conditions will also prevail in the south part of the Sinai Peninsula, the range of mountains of the Red Sea and Middle Egypt.\r\n\r\nIt will be hot in Upper Egypt over the hours to come. However, it inclines t be cold at night.\r\n\r\nWater mist hangs over the Delta in the morning. Strong winds blow up in the mountains of the Red Sea and the southern part of the Sinai.\r\n\r\nBoth Cairo, Middle and Upper Egypt would be exposed to fresher winds as the day progresses. Major temperature degree in Cairo will be 29 C and the minor degree will be 18 C.\r\n\r\nOn the other hand, the experts warn of the \u00a0Coronavirus pandemic may affect the accuracy of the initial weather forecast model output originating from national and global weather prediction centers because of a cutback in the number of aircraft flights that generate vital weather data, according to the European Centre for Medium-Range Weather Forecasts (ECMWF) and other experts.\r\n\r\nThe aircraft collect temperature and wind data, among other information, that help improve the initial atmospheric conditions that drive global and regional weather forecast models. This data is used routinely to improve the forecasts created by national weather prediction centers across the globe.\r\n\r\nThe pandemic has drastically reduced the number of such flights in Europe and increasingly in the U.S. This impact will be a reduction in global forecast performance. For regional models, the impact may be even greater.\r\n\r\nRegional models have the ability to resolve high-impact weather, such as thunderstorms, said AccuWeathers Scott Mackaro, vice president, Science, Innovation & Development. Information about the vertical structure of the atmosphere is vital and already sparse. Aircraft measurements provide just that.
