"Ĉu neĝos morgaŭ?"
Translation:Will it snow tomorrow?
Mi esperas, ke gxi negxos. (Though your comment was in August and mine's from January, so...)
I put "it'll rain tomorrow?" and duolingo didnt take it! anyone know why?
If you look at the translation at the top of the thread, you should notice two differences. First, yours is a statement but the correct translation is a question. Second, the correct sentence has to do with snow and yours says rain.
Let me know if there are other details which are not clear. Gotta run for now.
