During roughly an 18-hour period from the evening of Wednesday the 10th through the early afternoon of Thursday the 11th, much of South Central Nebraska observed a fairly classic clash of the seasons (spring versus winter). More specifically, what started out as a burst of thunderstorms (some severe with hail up to golf ball size) steadily gave way to a varied mix of sleet, brief freezing rain and eventually snow as colder air rushed in, with some far northern and western counties measuring 4+ inches of snow (especially Valley/Dawson). At least brief, off-and-on blizzard conditions occurred in these same northern and western counties, thanks to sustained north-northwest winds averaging 20-30 MPH/gusting as high as 40-50 MPH. However, as it turned out, truly widespread/crippling blizzard conditions did not come to fruition with this storm system, not only because snow amounts largely fell short of forecasted expectations, but also because winds ended up being less-intense. This was the last snow event of the 2018-19 season within South Central Nebraska.
Breaking things down in greater detail, and also in chronological order, Act 1 of this storm system occurred during the evening of the 10th (mainly 8 p.m. to 1 a.m. CDT) as a number of strong to occasionally-severe elevated thunderstorms tracked from southwest-to-northeast across the area. Nearly all of these storms produced at least small hail (in some cases copious amounts), but a few also yielded larger stones ranging from penny up to golf ball size. The greatest concentration of ground-truth hail reports originated from Kearney and Buffalo counties, including the largest, golf-ball size stones along a corridor between Kearney and Shelton. Within this area, one of the most notable reports involved significant amounts of (mainly small) hail piling up to 4 inches deep on Interstate 80 between Kearney and Gibbon, causing multiple vehicle slide-offs. All local convection occurred solidly to the north of a surface cold front that had already surged well-southward into Kansas, with evening surface temperatures in most of South Central Nebraska only in the 30s. Despite these chilly readings, the mesoscale environment was primed for hail storms, with elevated most-unstable CAPE up to around 1000 J/kg and stout effective deep-layer wind shear of 50-70 knots. By late in the evening, but especially between midnight and sunrise on the 11th, the weather focus steadily transitioned from thunderstorms to winter weather (Act 2), as the invasion of colder air from the northwest allowed cold rain to transition to a mixed-bag of freezing rain and sleet, and eventually snow. In most areas, the vast majority of snow fell prior to 10 a.m. CDT, but lingering pockets of pesky light snow and blowing snow persisted into the evening before all wintry precipitation ended. As for snow amounts, most areas along and east of Highway 281 and also south of Highway 92 received only a trace up to around 1. However, totals ramped up farther to the north and west, with particularly Greeley/Valley/Dawson/Gosper/Furnas counties reporting fairly widespread coverage of at least 2-4. The highest amounts in South Central Nebraska emanated from Valley and western Dawson counties, including 6 in Ord (NWS coop observer) and 7.7 four miles south of Cozad (CoCoRaHS). Any icing impacts from brief freezing rain were quite minimal.
Concluding with a brief look at the meteorological setup, the driving force in the mid-upper levels was a large-scale trough over the Central Plains, anchored by a closed low pressure system that slowly migrated from eastern Colorado on the evening of the 10th to far northeast Nebraska by early-evening on the 11th. During this same 24-hour time frame, the associated strong surface low pressure center started out over south central Kansas on the evening of the 10th (roughly 986 millibars).  By early-evening on the 11th, it had drifted to the NE/SD/IA border area, and weakened slightly to around 992 millibars.
