Although not overly-impactful to area travel, Thursday the 16th featured a fairly noteworthy late-season snowfall across the majority of South Central Nebraska (this was the final snow event of the 2019-20 season). Most counties along and north of the Highway 6 corridor measured somewhere between 2-5 of wet snow, with the highest concentration of 4 to localized 6 amounts concentrated within northeastern counties including: Greeley, Nance, Merrick, Hamilton, Polk and York. Snow accumulated most efficiently on grassy and elevated surfaces, while much of it melted/accumulated minimally on area roads due to marginal, near-freezing temperatures. Per NWS coop observers, some of the highest totals featured: 5.9 north of York, 5.5 in Greeley, 5.3 in Osceola and 5.1 at Bradshaw. In the Tri Cities, official amounts ranged from 2.4 at Hastings to 3.8 at Grand Island. At the York and Greeley NWS observer sites, the aforementioned daily snow totals over 5 were the highest on record for so late in the spring! At Grand Island and Hastings, this was the 6th-highest and 8th-highest daily snowfall this late in the spring, respectively. Thanks mainly to the wet nature of snow, drifting was fairly minimal, despite steady northeast winds sustained around 20 MPH/gusts around 30 MPH. Although the sight of fresh snow cover was rather unusual for mid-April, it actually turned into a distant memory quite quickly, melting rapidly on Friday the 17th thanks to high temperatures reaching the low 50s F.
Digging into event timing, snow broke out across most of the area between 8-10 a.m. CDT, peaked in intensity late-morning through late-afternoon, and gradually departed from west to east during the evening with the vast majority of locations snow-free by 10 p.m. CDT. In the mid-upper levels, the primary player was strong upper level divergence and resultant mid level frontogenesis (quite pronounced at 700 millibars), focused slightly downstream from a positively-tilted parent trough axis positioned over the northern Great Basin and Central Rockies. At the surface, the steady (but not overly-strong) northeast winds were driven by a modest pressure gradient between deepening low pressure centered over the northern Texas Panhandle and broad high pressure stretched from the Northern Rockies into the Midwest. Temperature-wise, the 16th was incredibly cold by mid-April standards, featuring daytime highs of only 32-35 F across most of South Central Nebraska. In fact, this snow was the precipitation highlight of a markedly-cold, six-day stretch centered from the 12th-17th. At Hastings airport, the average daily temperature over these six days of 34.4 F (16 degrees below normal) established a record for the overall-coldest six-day stretch so late in the spring.
