Primarily between 2:30-9:30 p.m. CDT on this Friday afternoon and evening, scattered to numerous thunderstorms rumbled across much of South Central Nebraska, including a varied mix of isolated pulse/single cells, multicell clusters and small-scale line segments. Like the more spotty activity the day prior, the majority of this convection was non-severe, simply producing beneficial rainfall, gusty winds of no more than 40-50 MPH and isolated pockets of very small hail. However, a handful of storms became strong to marginally-severe. Ground-truth reports were quite limited, but included nickel size hail near Holbrook and a measured wind gust to 59 MPH near Shickley (unofficial mesonet). Based on radar data, marginally-severe storms might have also affected at least small portions of the following counties, but with no verification: Greeley, Howard, Nance and Gosper. Rainfall-wise, amounts across the 24-county area were highly variable, with most areas receiving no more than one-quarter to one-half inch, but ranging from hardly a drop in some spots, to several small pockets at least 1-2, particularly within portions of several counties along/north of Interstate 80. However, there were no reports of impactful flooding.
Turning to the meteorological background and event evolution, this was another case of marginally-severe convection forming in a moderately-unstable, but weakly-sheared environment. In the mid-upper levels, wind fields remained unusually weak by early-June standards, thanks to South Central Nebraska residing under broad ridging stretched across the heart of the United States from north-northwest to south-southeast...well-removed from any larger-scale troughs centered over the northeastern and northwestern states. However, on the smaller-scale, a weak disturbance (possible MCV) drifted east into South Central Nebraska during the afternoon-evening, likely supporting more widespread convective coverage versus the day before. At the surface, there were no notable features in the pre-convective environment, only light south-southeasterly breezes and hints of a weak low pressure center over Nebraska. As temperatures climbed into the upper 80s-low 90s (F) by mid-afternoon, storms readily developed in a weakly-capped environment featuring moderate mixed-layer CAPE of of 1500-2500 J/kg, but seasonably-paltry deep-layer wind shear only around 20 knots at best. The majority of convection early in the event (mainly 2:30-5:30 p.m. CDT) was more discrete in nature and focused within northern/western portions of South Central Nebraska. Thereafter, activity trended a bit more upscale/linear over the next few hours as it progressed through mainly south central/southeast local counties, before departing southeastward into mainly northern Kansas by sunset.
