I have seen everywhere, and it is like this in the dictionaries, неужели as an exclamation. Неужели это так? Can it be like this ? (!) but I find it in a non exclamative expresion:
A deep athmosferical depresion is on the zone, по этому неужели зимно в этом регионе продолжается довольный сильный снегопад. ...because of this, it is possible that a rather strong snow-fall keeps the winter in this region.
Is it also admited this use of неужели? Thank you.
