We here in Israel have been saying V’Sein Tal Umatar for two months now. Not a drop of rain fell, and in fact November was the driest on record in the last 50 years. Yet on December 5th, when Acheinu Bnei Yisroel in Chutz La’aretz started saying it, Yerushalayim received the first downpour of the year (and significant amounts in the rest of the country too.) In fact someone mentioned to me on Shabbos that it started raining exactly when they started saying it in Australia….
I guess Eretz Yisroel needs the zechusim of ALL of Klal Yisroel together…especially pre-Shemittah
So thank you Hashem for answering the Tefillos of Klal Yisroel.
