Hidalgo County, TX Roof Snow Load - 0 psf
What ASCE 7 says about snow load in Hidalgo County
That's Hidalgo County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from.
Converted to something you can actually eyeball on a roof: about 0 in. of fresh powder, 0 in. once it settles and packs down, or just 0 in. if it's turned to ice. This county’s ground snow load maps to zero - snow load is not a driver of roof design here.

How much it actually snows in Hidalgo County
Most winters bring Hidalgo County roughly 0.2 in. of snow - NOAA's normal at MERCEDES 6 SSE, TX US, 28.9 mi off. That station is far enough away (28.9 mi) that local snowfall - especially at a different elevation or near a lake - can run noticeably higher or lower than this figure. (fresh vs. packed vs. ice explains why.)
Read this before you rely on it
Hidalgo 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.
