I'm brewing two batches of grain mash, since im using a small pot.
Anyways, half is cooling outside right now, the other half is on the stove, I plan to combine the two afterwards then get it to 70°F to add the yeast.
How cold can the half outside get? It's -30°F (-34°C) outside (no yeast is added yet).

I suppose you want to know how cold does it need to be, so that once it is combined with the other half, you get 70°F ?
It depends on how hot is the wort on the stove, once you know that temperature, you can calculate it based on the volume. In any case, you can't let it freeze or it will be hard to transfer.
If one half is close to the freezing point and the other is close to the boiling point, once mixed you will be in between (about 122°F). You might need to bring it back outside to get to 70°F.
