The second in a series of weather events impacted south central Nebraska late on Valentine’s Day and the 15th.
After a period of light mixed precipitation near the Kansas border, areas to the south and east of Grand Island, including U.S. Highways 281, 81 and 6, experienced a period of freezing drizzle which resulted in a glaze of ice on area roads and surfaces. Just before midnight on the 14th, a snow band formed from Valley to Dawson counties. This snow band, roughly 60 miles wide, moved east across south central Nebraska overnight, and into eastern Nebraska by mid-morning on the 15th. Aside from the light glaze in some areas, a dusting to 4 inches of snow fell. Most of the snow fell northwest of a line from York to Red Cloud. Within that area, some of the heavier amounts included 4 Ashton, Genoa and Cozad, 3.8 near Orleans and 3.2 near Shelby. Most of the snow amounts reported were in the 1 to 2 inch range.
Unlike the winter event a few days prior, there was a weak surface low in southern Kansas. The 700 MB weather chart depicted a clearly defined, positively-tilted trough moving across the area bringing a mixture of precipitation. As the trough passed, dry air filtered into the mid-levels of the atmosphere. The weak lift overriding the shallower cold air near the surface resulted in a period of freezing drizzle. Eventually, mid-level moisture increased, and when teamed with increasing frontogenesis in the 700 to 500 MB layer, the band of steadier snow formed.
