Newton County, AR Roof Snow Load - 10 psf
What ASCE 7 says about snow load in Newton County
That's Newton County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from. 7 psf is what the ground-load formula alone gives; Newton County's 10 psf low-slope minimum (§7.3.4) beats it, so that figure is the one that governs on flat and low-pitch roofs.
Converted to something you can actually eyeball on a roof: about 22 in. of fresh powder, 8 in. once it settles and packs down, or just 2 in. if it's turned to ice. This is a modest add-on to standard roof loading - ordinary residential construction carries it without extra bracing.

Read this before you rely on it
Newton County's number above is ASCE 7-22's default case, not a custom calculation: ordinary residential occupancy, heated, sited on ground that's neither fully sheltered nor fully exposed. Any one of those changing - pitch, exposure, heating, occupancy - moves the real figure.
