Episode narrativeepisode_narrativeSeveral storms produced hail up to the size of golf balls on this Thursday. Storms began forming early, with the first storms forming just after 12 p.m. CST over Webster, Nuckolls, and Thayer Counties. These storms rapidly intensified, merged into a solid line, and lifted north into Adams, Clay, and Fillmore Counties. These storms produced hail up to the size of golf balls in a few locations over Adams and Clay Counties. This line of storms stalled and gradually weakened from west to east. However, before the storms weakened over Fillmore county, multiple storms moved east within the line and resulted in 2.57 inches of rain falling between 1 and 3 p.m. CST in Geneva. A CoCoRaHS station reported a 24-hour total of 3.55 inches just west of Geneva. Before the tail end of this line exited Fillmore County, a couple small storms developed just to the south over Thayer County and they produced 1 inch hail in Gilead. While all this was in progress, another line of storms had formed over north central Kansas and this line lifted north as well. Just as the initial line of storms exited south central Nebraska and moved east into southeast Nebraska, this line of storms crossed the border into Franklin, Webster, Nuckolls, and Thayer Counties around 3:45 p.m. CST. The storms then started weakening as they lifted further north. However, nickel to quarter size hail fell in a few spots and a severe wind gust of 62 mph was measured near Glenvil. No other storms were severe after 5 p.m. CST.||The depiction of surface fronts was complex. Occluding low pressure was over southern Manitoba. Early in the day, a slow-moving cold front extending south from Minnesota and Iowa into Nebraska. This front appeared to weaken during the afternoon. Meanwhile, a quasi-stationary front extended from New Mexico across Kansas into Missouri. This front lifted north through the day as a warm front, but was effectively forced back to the south as thunderstorm outflows cooled temperatures over Nebraska. In the upper levels, a longwave trough was over the western United States, with broad southwest flow from Texas to New England. A subtropical high was over the western Atlantic. During the day, a shortwave trough ejected out of the Desert Southwest into the Southern Plains, aiding in thunderstorm development. Just prior to thunderstorm initiation, temperatures were generally in the upper 70s and lower 80s, with dewpoints varying from the upper 50s to lower 70s. This surface environment was overlaid with very steep mid-level lapse rates around 9 degrees C/km, resulting in MLCAPE between 2000 and 3000 J/kg. Strong mid-level winds, combined with directional shear in the low-levels, produced effective deep layer shear between 40 and 50 knots.
