i've been driving in snow like that for close to 25 years here in northern Mn. and working rotating shifts means lots of night driving. you have options: add driving lights as they put their light below bumper level and will have better distance than traditional fog lights, or rewire your fogs so you can use them independently.
for true fog lights, i prefer the yellow lenses or bulbs as i get a clearer picture with less glare compared to clear. also, fog lights don't have the distance of neither your regular headlights nor driving lights.
in your situation, it would be easier, imho, to get some driving (also called cornering) lights and wire them independently then just use them with your light switch in the center position as has been stated already.
