What zone 3A means for a Longview window
Gregg County's normal precipitation runs about 50.5 inches a year, with 0.9 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Longview.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Longview buyer benefits from checking both instead of assuming one implies the other.
Data: U.S. EPA / DOE, ENERGY STAR, ENERGY STAR Version 7.0 Climate Zones by County/ZIP (Windows, Doors, and Skylights) (V7.0); Pacific Northwest National Laboratory (DOE Building America), Guide to Determining Climate Zone by County: Building America and IECC 2021 Updates (PNNL-33270) (2021 IECC), from the nearest NOAA station 2.5 mi away.

Ask specifically about design pressure and impact rating for Longview, not just energy performance, if either risk rating comes back on the high side.
