The science behind snow needles
February 19, 2025 / /
AUSTIN (KXAN) — Did you know that no two snowflakes are ever exactly the same? The size and shape of each snowflake are unique, a result of the constantly changing dynamics of our atmosphere.
When snow falls, the temperature and humidity conditions in the dendritic growth zone, often referred to as the “snow growth zone,” help shape these ice crystals. This zone typically resides about 5,000 feet above the surface.
On Wednesday morning, snow needles made an appearance across portions of Central Texas.
These snowflakes are long and thin, with pointed tips, and they form when the surface temperature is around 23°F.
