In my opinion I wouldn't worry if you go from Frozen to liquid currently because I think once the ull gets East of us you will change back to frozen in my opinion. I could be wrong but that is my best guess on how this may go.
One positive thing I saw last night and this morning was we went from 66 to 31 this morning all under cloudy skies. So it can be done with the right thermals. We will see.
