Depends on difficulty. On your winter harshness is set to moderate, 14 to 18C should be fine.
1. Reco you get min 3 beds for maximum rest. Esp when you do 2 guards up at night or for future ppl sick/injured etc
2. Start hunting firearms. Gun, shotgun. That way u will only need one person up and the raiders will have less chance of stealing your loot.
3. Start focus on managing the "emotional" side of your group.  Depends on your total days before ceasefire (40-80), the end game is about managing the emotion of your survival. Else they will do lots of things to themselves. lol. Radio, Guitar, sofa + tobacco helps for certain character. Seems like you are missing a guitar. You can find them at.... I hate spoilerers so I leave it to you to explore 
4. Get one more rat trap. 2 is max so keep those trap running. Ramli Rat Burger FTW!
5. Upgrade your cooker so you use less fuel for every meal prep.
6. So many other things, but best u self explore.

Above are just some minor things to take note if you are going for the long haul. The best part of the game is when you try to find the best way to survive. Once ppl tell you the major sequence, they will have killed your joy.

I have tried 80 days till ceasefire, early winter, harsh winter, long winter, aggressive hostile. 3 adult and one kid. And I can tell you its a f***ing warzone out there. lol
