I'm trying to figure out how you maintain frost protection for the now-exposed portions of the footings?
In the midwest, we have to keep the bottom of footings at least 36 inches below grade per code.
Obviously they're unprotected temporarily.
I think the big concern with the 36 inches below grade is to prevent the lifting that can occur from chronic freeze-thaw cycles.
At least that's what I hope. Projects like this are not uncommon around here this time of year. If the temperature drops much below 0 degrees F they'll cover and insulate, but warmer than that they just rely on a little extra calcium in the mix and other accelerators. I've never heard the concern about the footings freezing.
Here are a few pictures of what it looks like today. We got some snow overnight.
