Lake-effect snow is most common near the Great Lakes, but while rare in North Texas, it can happen here too.
Lake-effect snow was expected to be possible in areas south and southeast of the larger North Texas lakes, such as Lake Lewisville or Lake Ray Hubbard.
Lake water temperatures are between 40-42 degrees, and the air will be cold enough to produce snow flurries.
Flurries were reported Wednesday in many areas south of North Texas lakes. Any snow that fell amounted to a dusting and did not accumulate.
Snow visible in Dallas County near Spur 408 at Illinois Ave.
Cold air moving over the warmer water causes warm air with moisture to rise. When the winds are at the appropriate direction and speed (winds can`t be too strong or too light and must have a long enough fetch over the water) the lift allows for clouds to form and eventually precipitation.
