The unusually hot weather will come to an end tomorrow afternoon.
A cold front moving from the northwest will bring tropical showers ahead of it Wednesday morning, raising the possibility of flooding in southern areas. The cold front itself will bring a period of rain in the afternoon and evening over much of the country, with showers possible on Thursday as well.
There will be strong winds and dust as well on Wednesday, with dust persisting over the south on Thursday.
The weather will also turn much colder -- with high temperatures on Thursday 10 to 15 Celsius lower than today (Tuesday). Temperatures will warm a bit towards the end of the week, but early next week (the end of Pesach) will likely see a chill in the air once again.
The end of the month will most likely end on the warm, if not hot side.
