| Episode narrativeepisode_narrative | Heavy rain and flash flooding occurred on this Saturday morning, along with a few reports of severe hail and winds between Grand Island and Hastings. Between midnight and 1 a.m. CST, small, isolated single-cell thunderstorms developed over central Nebraska, between Ainsworth and Lexington. As the night progressed, they were joined by more storms with an increasing trend toward a multicell convective mode as a common cold pool formed. The southern end of the developing MCS drifted eastward into Valley and Sherman Counties, with the deep convection on the west side of the MCS remaining quasi-stationary. After 6 a.m. CST, the northern portion of the MCS (over the Sandhills) weakened while the southern portion became dominant. By 6:30 a.m. CST, the dominant storms evolved into a short east-west oriented squall line across Sherman and Howard Counties. This line subsequently dropped southeast across Hall between 7 and 8 a.m. CST, then continued all the way down to Hebron, exiting south central Nebraska a little after 10 a.m. CST. Cell training produced a north-northwest to south-southeast oriented swath of 3 to 5 inches of rain across Valley, Sherman, and Howard Counties. Minor flash flooding resulted in water covering roads in some areas. As the storms tracked across Hall and northern Adams Counties, some low-end severe hail (dime to quarter size) occurred in a few spots. The most significant report of severe weather was a blown over tractor-trailer near the Interstate 80 interchange at Alda.||This MCS developed far from any fronts, but on the eastern edge of a tongue of higher theta-e air in the lower levels, in the presence of warm air advection and deep convergence. A 25-30 kt low level jet over and just west of the genesis region. The front that moved through the region, on Wednesday the 27th, was quasi-stationary from the Ohio Valley southwest to Oklahoma, with its western extent banked up against the Rockies in Colorado and Wyoming. High pressure encompassed much of the north central and northeast U.S. These elevated thunderstorms developed in a regime in which surface temperatures were in the lower to middle 60s, with dewpoints in the upper 50s to lower 60s. In the upper levels, the Westerlies were weak and covered the northern half of the U.S. They were fairly zonal in character, but did exhibit a slight ridge over the Northern Rockies, with a pair of weak shortwave troughs moving through the mid-Mississippi Valley and Nebraska and Kansas. This MCS occurred along the eastern fringe of a tight instability gradient in which MUCAPE was between 500 and 900 J/kg. Mid-level lapse rates were moist adiabatic. Effective deep layer shear was between 35 and 45 kts. |
