| Episode narrativeepisode_narrative | Thunderstorms produced damaging winds and some low-end severe hail over several counties in south central Nebraska on this Tuesday evening and night. Scattered single cell thunderstorms began developing around 3 PM CST from central Kansas northeast into southern Nebraska. The formation of numerous cells quickly resulted in a transition to a multicell convective mode by 4 PM CST. This nearly continuous line of storms lifted north, crossing much of south central Nebraska between 5 and 8 PM CST. As this occurred, another cluster of multicells over north central Kansas merged and moved northeast, eventually taking on the shape of a bow echo. This line of storms affected areas from Nelson and Hebron up to York between 630 and 730 PM CST. More storms over southwest Nebraska and northwest Kansas eventually consolidated and crossed south central Nebraska as a small scale bow echo between 10 PM and 130 AM CST. The initial line lifting north produced a fairly large area of severe winds from the state line north to Holdrege and Grand Island. A grain bin was removed from its foundation and deposited on Highway 74 near the town of Roseland, in Adams County. A tractor-trailer was blown over on Interstate 80 as well, just south of Grand Island. The highest gust measured was 67 mph at the Holdrege airport. A brief EF-0 landspout tornado was photographed near the town of Exeter. The eastern portion of this line produced the most hail, with a few reports of 1 inch hail over Fillmore, Nuckolls, and Thayer Counties. The bow echo taking shape from Nelson to York snapped a few power poles in eastern Thayer County. The last line of storms to cross the area produced mostly sub-severe winds of 50 to 55 mph. However, severe winds did occur in a couple locations. The highest measured gust was 64 mph in the town of Norman, in eastern Kearney County. A brief EF-1 tornado also occurred in Clay County, just north of the town of Edgar. It was on the ground for approximately 2 miles, damaging outbuildings, trees, and overturning irrigation pivots. This tornado occurred just after midnight CST. Repeated thunderstorm activity resulted in 1 to 2 inches of rain over much of south central Nebraska. There were even a couple reports in excess of 3 inches. Ditches were full of water, and even some minor flooding of low-lying areas occurred near Highway 136 just west of the town of Inavale, and also near the intersections of Highways 81 and 92 west of Osceola.||Low pressure was over South Dakota, and its trailing weak cold front moved into south central Nebraska during the day. It became stationary as low pressure formed over southeast Colorado and deepened to near 990 mb. In the upper-levels, a longwave trough was over the Western U.S. with a ridge over the East. A strong shortwave trough lifted out of the Desert Southwest into the Southern Plains, while a closed low dropped into the Pacific Northwest. In the preconvective environment, an elevated mixed layer had overspread a moist boundary layer. Mid-level lapse rates were between 8 and 9 C/km. MUCAPE was between 3000 and 4500 J/kg. With strong dynamic forcing, deep layer shear was very strong, between 40 and 60 kt. |
