On the first Monday and Tuesday of this month, we saw a different kind of snow maker impact parts of eastern Nebraska. This snow wasn't caused by a whole system or even just a front passing through. Instead, it was caused by steam rising out of smokestacks near Norfolk interacting with cold air and plenty of moisture!
This snow impacted areas almost due south and slightly southeast towards Lincoln on Monday. The light snow continued for the better part of the day and even laid down almost two inches of snow from areas near Stanton down towards David City.
On Tuesday, it happened again. This time the northwest wind pushed the snow plume towards Omaha and brought not only light snow to those in its path, but also from freezing drizzle which prompted the National Weather Service in Valley to issues a Winter Weather Advisory for a while during the morning.
While this phenomenon is rather rare here, it bares a similarity to lake effect snow.
