Tá sé ag báisteach - is common in Conamara. But the "ag" is usually/often left out in speech.

I know that this makes sense grammatically, but I have never heard anyone actually say it. Is it used? I would say, 'beidh sé ag cur báistí' which I know is 'it will be raining' and not 'it will rain'. Just wondering if the construction, 'cuirfidh sé báisteach' is actually used?
"Cuirfidh sé báisteach" - I suppose it is right grammatically. But personally I wouldn't use it.
I'd say -
Beidh sé [ag] báisteach amáireach.
Tá sé geallta a bheith ag báisteach amáireach.
