During the mid to late evening hours on this Friday, the northern end of a short bow echo raced across extreme South Central Nebraska. The northern bookend vortex tracked along Highway 136, just north of the Kansas border. The strongest wind gusts and some limited damage were concentrated over Furnas and Harlan counties. Winds were measured at 78 mph just south of Cambridge, with several other gusts estimated at more than 60 mph. As the bookend vortex moved east the severe weather greatly diminished, with only some small branches downed in Campbell in Franklin County. Just prior to the bow echo entering South Central Nebraska, an isolated thunderstorm developed over Howard county just before 7 p.m. CDT. The storm was nearly stationary for its entire life and began weakening around 8 p.m. However, while at its peak intensity, it produced hail up to 1.5 inches in diameter just north of St. Paul.
The bow echo formed over the High Plains of northeastern Colorado, north of the primary polar front that was stationary over the Southern Plains and south of a secondary front dropping through the Northern Plains. The flow aloft was fairly zonal with a weak embedded shortwave trough moving from Wyoming and Utah onto the High Plains by early evening. Late afternoon temperatures were in the lower to middle 80s with dewpoints in the lower 60s. This resulted in MLCAPE between 1000 and 1500 J/kg and 0-6 km shear was around 40 knots. By the time the convective line moved in, temperatures had dropped to around 80 degrees. Undoubtedly, further diurnal cooling limited the severity as the line progressed eastward.
