Dec NG options expiration day plan

It seems I will likely get assigned on my Natural Gas Dec 3.5 put. Normally, futures contracts expire the day after options expiration, but due to Thanksgiving holidays, the Dec contract expires on Mon, 11/28.

I have a few options.

-If the futures contract closes above 3.5, I don't have to do anything (the least likely case considering where markets are traded at right now).

-If the futures contract closes around 3.5 (not likely happen either), but not sure if I get assigned or not. In this case, I need to see a settlement price and if I get assigned, I'll sell the Dec futures and buy Jan futures outright.

-If it closes below 3.5, I'll sell the Dec futures and buy the Jan as quickly as possible.

Since markets are still open after the pit session closes (1:30 pm CT), I can wait to roll over later. Furthermore since electronic markets open during Thanksgiving holidays, I don't have to roll over today, or even wait until Mon 11/28, the futures expiration day. However ThinkOrSwim says any assigned contract gets liquidated 'any time' during the expiration day, so I want to make sure I don't get liquidated by someone else except me because if I do and markets shoot up until I roll over, I might miss any move.

My break-even point based on Dec contract is 3.416 (3.5 - 0.084 (the premium I sold for) = 3.416). If I have a few hundreds dollars of profit, I may simply exit the trade (meaning offset the Dec NG, but not buying Jan) and I start over by selling Jan put.

Now the twist of this whole thing is due to Thanksgiving, we have Nat gas report coming out today (usually Thursday), so it might be good or bad for me. Shortage usually makes NG go higher but not necessary. The weather has been pretty mild so far, but I'm betting on an old saying the hotter the summer gets, the colder the winter gets. It was one of the hottest in the last 10 years.

I'll update regardless what happens.
