From the USDA Forestry Division, they say the snow load for Missouri is 10-20psf. I would reccomend going with the higher of those
Snow load depends on geographic location, not on roof pitch. Most of Washington falls into the 25 psf snow load. Snoqualmie, for example, has a 50 psf snow load since it receives a higher amount of snow fall than an area such as Seattle. Your county building department can answer this question for your specific location and/or has a snow load map where you can look it up yourself.
The ground snow load varies. Use the free snow load calculators at Jabacus (related link) to find the snow load for a specific location.

In general, Colorado does.

A 4-12 pitch with a 30lb snow load will hold approximately 6 feet of wet snow. If you went to a 40lb-snow load and kept the roof pitch at 4-12 your roof would be able to hold 8 feet of wet snow. We don't get that much dry powder in New England...:)
