Don't know about your weight, I'm almost exactly half your weight. I do 15 front - 18-20 rear. I also have decades of missing things at high speed on a dirt motorcycle. I am losing some of the early anticipation thinking this last year. I ride with a guy about 220-230, who is very good and he uses about the same in the front, and more in the back. It also depends on the size of your tires. A big tire has more air cushion protection from a hole or a rock.

5 inches of snow has a huge effect on the power to propel the bike. Especially if there is drifting in places, making it deeper. Get out there anyway. Experiment with different pressures.

I use Schwalbe Marathon Winter 26x1.75 tires at around 55 PSI all the time. I have run them at lower pressure, but then they feel sluggish on the pavement and the last thing I want is a pinch-flat when I'm out after a 5" snowfall. I have also found riding through 2-3" of powder is manageable with these tires, but much more than that, and it's not really fun anymore. Plowed or snow-packed streets are fine.
