At what tempratures will a Red Latan start to struggle "long term"

[Palmfarmer]

I have a Red Latan Outside in pot I know the temprature for immidiete damage is around 0c. However that is not what i am worried about about. In a few weeks the temps will drop to around 15-20c in daytime and 5c in nighttime for several weeks if not over a month. I heard Latans would start to struggle going under 20c for longer periods of time and eventually die, is this correct? Should i put it inside permenantly in a couple of weeks time or should it do fine outdoors?

They leaf burn at 26-27f.

Mine spear-pulled after -3C. It did go on to recover but I was in despair for a time. I suggest you keep it indoors as long as nights fall below 5C. This is not a cold hardy palm

I have had one in the ground in South Texas for 10+ years with occasional brief 0 Celcius, and 48 hrs under 5c. It is doing well. Probably more tolerant if in the ground in your climate since the soil temperature will fluctuate much less than in a pot.
