Sunday will be partly cloudy, in the north of the country and in its center, local rain is expected and there may be some thunderstorms. In the northern Negev there may be light rain. In the Jordan Valley, the Judean Desert and the Dead Sea, there is a slight fear of flooding. There will be a further drop in temperatures and will be lower than usual for the season. 

How does all this happen? We are still in the spring, and a cold block of air from the Eastern European region on its way to the eastern Mediterranean is expected to pass us. Waiting from Eastern Europe is expected to rain during Sunday through Monday morning, north and center. Monday will be partly cloudy to fine. Temperatures will rise, but they will still be lower than usual in the season. In the morning there may be drizzle in the north of the country. 

Nahum Malik, a meteorologist forecaster, points out that "this is an unusual rain system for this period, and its scope is still unclear."
