Another burst of late winter visited mainly northern portions of South Central Nebraska on Monday the 22nd, as parts of Valley, Greeley and Nance counties received 1-4 inches of wet snow from a rather quick-moving precipitation shield that passed through the area primarily between 11 AM and 2 PM CDT. Although snow did not last all that long in any given location, it accumulated quickly as some of the highest totals per NWS cooperative observers and NeRAIN observers featured 4.5 nine miles northwest of Ord, 4 at Arcadia and eight miles north-northeast of Scotia, and 3.5 in Ord. Accompanying this falling snow was sustained north winds around 20 MPH and gusting over 30 MPH behind a sharp cold front. While accumulating snow was confined to these far northern counties, temperatures remained just warm enough across the majority of the 24-county area to keep precipitation in the form of a steady, chilly rain. Temperature-wise, this passing front ushered in a very cold few days by late April standards, as Ord airport only registered highs of 39 and 37 degrees, respectively, on the 22nd and 23rd.
In the mid and upper levels, forcing for this event was provided in part by lift associated with a low-amplitude lead shortwave trough ejecting out ahead of a larger-scale, positively tilted trough centered along an axis from south central Canada to Idaho. Central Nebraska was also positioned under a pronounced area of upper level divergence between the exit region of a 110 knot upper jet streak oriented from northern Colorado into western Kansas, and the entrance region of another jet streak centered from northern Minnesota into Ontario. At the surface, mid-day analysis depicted the leading edge of the aforementioned strong cold front aligned from extreme southwest Kansas into southeast Nebraska, with temperatures across the local frontal zone ranging from 29 degrees at Ord, to 38 in Hastings, to 53 in Hebron.
