Your best defense against having to drive in winter weather is not latitude, but having enough 'spare' time built into your schedule to simply sit it out, let the road crews do their job, and then (and only then) resuming your drive. And the best way to have that spare time is to take the shortest possible all-Interstate route rather than adding hundreds of miles to your drive.
So, since this drive is going to take you five days if the weather is good all the way, you should schedule six days and just stick to I-70 to St. Louis, I-44 to Oklahoma City, I-40 into southern California and I-15 for the final leg into Los Angeles. If you were to swing south trying to use I-81/I-55 into Mississippi and then I-20/I-10 to Los Angeles, you'd have to schedule five and a half days (You'd be adding 250 miles to your drive.) and still wouldn't be assured of any better weather.
