Last Shabbat I was walking to Shul to learn a shiur and daven an early Mincha Gedola. Then the totally unexpected wildest storm struck and when I arrived in Shul I was totally soaked even my underclothes were wet. I was debating if I can stay, since I was already there, and daven Mincha early or maybe it would be better to return home and daven Mincha later?

As I answered you then, it would be better to go home and change, since davening in that condition may contradict a basic requirement of Tefila (Mishna Berura 91: 12) namely that one should dress when davening as is the custom is in that place to receive great and important people. (See questions 3624 – 25). Besides, you may incur unwillingly in squeezing clothing on Shabbos and also damaging the Shul property. Horav Shlomo Miller’s Shlit’a opinion is similar Rabbi A.
