Strong storm system brings severe thunderstorm and non-thunderstorm wind gusts to portions of south central Nebraska during the daytime hours of May 30th. An intense mid and upper level storm system, by late spring standards, shifted across the central and northern Plains and brought a few rounds of thunderstorms through the area. Severe thunderstorms occurred the night before over northern portions of the forecast area, and there was a several hour lull before a new line of thunderstorms developed in roughly the same area during the late morning hours. Isolated sub-severe hail was reported with this line north and northeast of Grand Island between 11AM and noon CDT before this line also shifted northeast out of the area.
Strong surface low pressure associated with the deep upper trough moved south-southwest to north-northeast across the forecast area during the late morning and early afternoon hours. The attendant dry line rapidly surged through the area and brought strong south to southwest winds. Most wind gusts were around 45-50 MPH, but a 58 MPH gust was observed at Central Nebraska Regional Airport in Grand Island. Damage was also reported in Polk County where medium sized tree branches were downed and fencing was damaged. This dryline swept much of the low to mid level moisture out of the area for several hours. However, wrap around moisture arrived from the west and northwest and allowed for new showers and thunderstorms to move through the area between 2PM and 5PM. Much of this convection was rather weak and high based, but it was strong enough to mix already strong ambient winds down to the ground. A couple 60 MPH wind gusts were measured in Dawson and Sherman Counties, and a 67 MPH gust was measured in Greeley County. No particularly serious damage was reported.
