You should be fine.
Hilo weather is very variable. It could be raining. It could be beautiful and clear. But even if overcast, the helicopters fly fairly low, and the weather at the Pu'u O'o vent could be totatlly different than what's in Hilo.
I would call the company (and my own recommendation is Blue Hawaiian) and ask what happens if the flight is cancelled because of weather.
