A few inches of light to moderate snow fell across a small portion of south central Nebraska on this Friday and Friday night. In the predawn hours Friday, an area of poorly organized, patchy mixed precipitation developed from northwest Kansas into western Nebraska. After sunrise, this area of precipitation blossomed and moved into south central Nebraska. North of highway 92, snow began falling. From 7 to 10 AM CST, a fairly strong, narrow band developed, within the larger precipitation area, and affected portions of Sherman, Valley, and Greeley counties. By midday, the intensity of the snow over these counties diminished, while the main precipitation shield, which had expanded and filled-in, moved into eastern Nebraska and western Iowa. While light snow continued to fall through the afternoon, there was no additional accumulation. A second area of burgeoning snow developed over western Nebraska and the Panhandle from late morning through the afternoon. By early evening, this area of light to occasionally moderate snow began moving into south central Nebraska. Snow fell across Sherman, Valley, and Greeley counties until midnight. This added to the accumulations from earlier in the day. Snowfall accumulations were very non-uniform, especially because of the banded nature of the morning snow. Two to 4 inches of snow generally fell across Valley, Greeley, and the northwest corner of Sherman counties. The greatest accumulations and coverage were over Valley county, where 7.0 inches fell near Elyria, with 5.5 inches 9 miles northwest of Ord, and 5.0 in Arcadia.
This snow event occurred in the absence of any surface features. A polar air mass was over the Plains, with 1022 mb high pressure over the Northern Plains during the daytime Friday. A stationary polar front extended from Ohio across the mid-Mississippi Valley to the Colorado-New Mexico border. By Friday evening, 1032 mb high pressure over southwest Canada began building into the Central Plains, overtaking the high over the Northern Plains. In the upper-levels, the flow was fairly zonal, but there was a broad trough over the Pacific Northwest and Northern Rockies. Embedded within this trough was a shortwave trough that progressed from Utah into Wyoming and Colorado by Friday evening. A strengthening 125 kt upper-level jet streak accompanied this trough; it was the left exit region that provided the lift needed to generate this snowfall.
