Between the afternoon of Friday the 9th and the evening of Saturday the 10th, two completely separate rounds of Advisory-worthy snow affected parts of the 24-county South Central Nebraska area, making for an active couple days of winter weather despite only modest impacts. Interestingly, the two snow events overlapped minimally in area, with the first round focused mainly within northern and central counties, and the second one across the south. This event summary discusses round 1, which occurred between the afternoon of the 9th and the pre-dawn hours of the 10th:
This first round of snow primarily affected areas north of Highway 6, and especially counties along and north of Interstate 80, which reported a fairly widespread coverage of 2-4 and isolated higher amounts to around 5. According to reports from NeRAIN/CoCoRaHS and official NWS cooperative observers, some of the highest totals featured: 5 northwest of Greeley, 4.7 west of Arcadia, 4.2 at Grand Island airport and 3.6 at Ravenna. Other official Tri Cities totals included 2.3 at Kearney and only 1.7 at the Hastings NWS office. Although not overly-strong, sustained north winds averaged 10-20 MPH with some higher gusts, causing at least minor blowing and drifting of the fluffy snow. Timing-wise, while some northern counties received minor accumulation early in the afternoon of the 9th, the primary west-east oriented snow band got going in the north between 4-6 PM before gradually slipping southward across the Interstate 80 corridor through the evening. Between midnight and 2 AM on the 10th, this snow band weakened and shifted east of the local area, signaling the end of round 1. Aloft, a large-scale, broad trough was in place over much of the United States with a series of jet streaks passing directly over Nebraska. This setup yielded a concentrated swath of mid-level frontogenesis, which in turn promoted the rather narrow, west-east oriented snow band that dropped the majority of accumulation. At the surface, the fluffy nature of the flakes was supported by a very cold airmass with temperatures only in the single digits above zero F. The breezy north winds resulted from steady pressure rises emanating southward across the Central Plains from high pressure in Montana and the Dakotas.
