Q. If you forget after December the 4th (to recite Tal Umotor) and the sidur instructs that you should say it at shma kolenu, where do you say it and what are the words you have to mention?

A. He should say Vesen Tal Umatar at the end of Shomea Tefila before Ki Ata Shomea Tefilas etc. (Mishna Berura 117: 16).

Shulchan Aruch (end of s. 117), Mishna Berura (ibid.) and many Poskim mention only Vesen Tal Umatar only, but it could be only an short form and the word Lebracha is included (Piskey Teshuvos ibid. n. 53.) Others outright add the word Lebracha (Kaf Hachaim 117: 37, Kitzur Shulcha Aruch 7.) However, Aruch Hashulchan (117: 6) and Shulchan Shlomo (117: 4) add also Al Pnei Haadama. Horav Shlomo Miller’s Shlit”a opinion is to include this complete last sentence.
