Help establishing a route from PA to warm south west in Jan

Head due south to SC or GA first, then turn west hugging as close to the coast as weather requires. Sit in south east Texas watching the weather and when there is a warm-up between cold fronts, make a dash across NM into southern AZ where you shouldn't have to worry about cold weather again as long as you stay in the lower elevations. Then mosey along to where ever in CA.
