Default LTFTs and Winter

I was wondering if anyone else has noticed a change in their LTFTs with the change in temperature lately. It just recently went from 60-70s to 20-30s here (got to love Missouri weather) and I happened to look at my LTFT and noticed that they were between 8-10%, where they had been between 3-5%.

Does this seem normal? My thoughts would be that the colder (more dense) air would require more fuel, but I though I would get some other opinions on this.

U know what's even better? It's supposed to get back up to the 50s tomorrow and the 60s by the end of the week. Haven't really noticed a change in my LTFTs...saw -3.9 and that was on startup this morning. I've been more conscious of rail pressure lately.
