If a person accidentally starts Baruch aleinu tonight (*Friday Dec 4th) he completes the beracha.
does he say Vesein Tal umatar livracha?
At first glance. Of course he does, it is the 60th day after the tekufa so we start asking for rain. Of course we don’t actually start until Motzei Shabbos only becasue we dont say baruch aleinu on shabbos. In a scenario where you would say Baruch aleinu (like above case) . Seem like you SHOULD say Vesein tal umatar
However I vaguely recall seeing in Ishei Yisroel that the fellow doesnt say vesein tal, since Klal yisroel hasnt started yet, so should continue to say vesein beracha. I looked and can’t find it. Does anyone know any sources that address this ?
