The extremely dangerous heat wave continues across the East Coast and much of the South-Central U.S. today. Record high temperatures are expected for some areas especially across the Mid-Atlantic where extreme heat risk conditions reside. There is a Slight Risk (level 2 of 5) of severe thunderstorms today for the northern Mid-Atlantic into portions of southern New England. Read More >
| A warm front sitting across south central Nebraska served as the focus for tornadic thunderstorms late Saturday afternoon and evening. Warm and moist air was drawn north into the region Saturday which led to very unstable conditions by late afternoon. As an upper level disturbance moved out of eastern Colorado, it helped provide a trigger to break the cap and allow thunderstorms to develop. Another factor was the dryline which started to push east along the warm front by 4 PM CDT. The first supercell thunderstorms developed near the intersection of the warm front and the dryline between 3 and 4 PM. At 5:28 PM CDT, the first tornadic thunderstorm of the day was reported in southern Furnas county, 3 miles south of Beaver City. By 5:32 PM, storm spotters reported that it was a large tornado just to the east of Beaver City. Initial damage survey of the area found that the tornado tracked from 3 to 4 miles southwest of Hendley, to near Beaver City, to near Stamford. A farm was damaged 2 miles north of Precept, and several trees were completely denuded of barks and limbs. The thunderstorm weakened as it moved further to the northeast, but large hail up to tennis ball size continued to fall across Furnas county. As the thunderstorm continued towards Harlan county, it became tornadic once again. At 6:04 PM CDT, a tornado was reported 5 miles northwest of Alma. Near Stamford, softball size hail caused extensive tree damage. The thunderstorm continued to move to the east northeast through Harlan and into Franklin county. In Franklin county, the thunderstorm generated a funnel cloud 4 miles north of the city of Franklin. As the storm tracked to the northeast through northern Webster county and into southern Adams county, several tornadoes touched down. The tornadoes caused some damage in Blue Hill in Webster county, then in Pauline in southern Adams county. Initial damage surveys estimates there were 3 seperate touchdowns. The first touchdown was about 3 miles northwest of Bladen. The second tornado was 2 miles south of Pauline, where Showboat road turns to the east, and it tracked northeast into Clay county near Spring Ranch. The third tornado was 2 miles southwest of Pauline, and it tracked just north of Pauline where it damaged trees and outbuildings. All three of these tornadoes have been initially rated as F1s. Meanwhile in Thayer county, a supercell thunderstorm quickly developed on the intersection of the warm front and an old outflow boundary from the previous nights convection. At 6:52 PM CDT, a tornado was reported 3 miles northwest of Hebron. The thunderstorm tracked to the northeast, and there were reports of tornadoes near Bruning between 7:12 PM CDT and 7:28 PM CDT. As the tornadic thunderstorm moved through the county; it also produced large hail up to the size of a baseball. This tornadic thunderstorm eventually moved east of our area into Jefferson and Saline counties. The original long lived supercell thunderstorm moved out of Adams county into Clay county where it spawned another tornado. The tornado caused extensive damage in Clay county. It was reported to be 4 miles northwest of Fairfield at 7:42 PM CDT. The tornado caused a freight train to derail near Fairfield. The tornado continued to the east and moved just south of Clay Center. Damage was reported to homes and farms to the south and east of Clay Center. At the USDA Animal Research Center near Clay Center, numerous large trees and power poles were downed, a calving barn was destroyed, and a well house was destroyed. The tornado lifted somewhere east of Clay Center, but the supercell thunderstorm continued into Fillmore county. The thunderstorm produced large hail up to golf ball size 9 miles north of Carleton. The next supercell thunderstorm to develop began its life in northeastern Jewell county in Kansas. The storm quickly developed rotation and moved northeast into Republic county then into Thayer county Nebraska. Storm spotters reported a tornado near Byron at 8:54 PM CDT.The tornado move towards the northeast and was reported near 5 miles north of Byron at 9:07 PM CDT. Another tornado was reported 2 miles west of Alexandria at 9:27 PM CDT. Several reports of damaged or missing outbuildings were received from just north of Alexandria. A storm chaser near the Fillmore-Thayer county line reported seeing cows flying through the air. A report has been received from a farm 4 miles north of Alexandria that their herd of 20 to 25 head of cattle was missing on the morning of May 23rd. The storm chaser also reported hail of 4 to 6 inches in diameter falling out of the thunderstorm. |

| 0.5 degree reflectivity scan completed at 5:33 pm CDT zoomed in on Furnas county. Note the hook echo evident in the higher reflectivity values. It is not always present and not all storms that have one will go on to produce a tornado. However, this is a strong indication that a supercell thunderstorm is capable of producing a tornado, and prior to the velocity data that Doppler radar provides, it was often the only radar basis for tornado warnings. | 5:33 pm CDT 0.5 degree SRM (velocity) scan. The cool colors (greens & blues) are targets moving toward the radar, which is located to the southeast. The warm colors (browns and reds) are targets moving away from the radar. When these colors appear adjacent to each other, it is termed gate to gate shear or a velocity couplet. |

| 0.5 degree reflectivity scan completed at 5:49 pm CDT, a tornado enters Harlan county and approaches Stamford. The tornado lifted before it reached Stamford. | 0.5 degree SRM scan completed at 5:49 pm CDT, Note that the velocity data indicates two strong circulations. The circulation near the Furnas-Harlan county line had a tornado on the ground as it approached Stamford. The second circulation to the southeast of Stamford eventually spawned a second tornado which moved just south of Orleans. |

 |
| 6:41 pm CDT 0.5 degree reflectivity scan zoomed in on Adams and Webster counties. Note again the obvious presence of a hook echo in the higher reflectivities in the extreme northesat corner of Franklin County. | 6:41 pm CDT 0.5 degree SRM (velocity) scan. The velocity couplet here depicts greater than 140kts of gate to gate shear, which is the sum of the magnitude of the inbound and outbound velocities. |
 |
 |
| 7:03 pm CDT 0.5 degree reflectivity scan zoomed in on Adams and Webster counties. The radar reflectivity shows a slight hook in the higher reflectivities extending towards the radar. The reflectivity signature is much more difficult to see because the storm is extremely close to the radar, and it moved through an area known as the cone of silence where the radar can not see the storm. | 7:03 pm CDT 0.5 degree SRM (velocity) scan. The velocity pattern shows that the storm is wrapped up on itself. The inbound and outbound velocities are seen in a spiral pattern. |
 |
 |
| 7:29 pm CDT 0.5 degree reflectivity scan zoomed in on Adams and Clay counties. The tornadic thunderstorm has emerged from the cone of silence. The hook echo is no longer readily apparent, but the storm inflow notch is apparent by the lower reflectivities just south of Glenvil. | 7:29 pm CDT 0.5 degree SRM (velocity) scan. The velocity pattern shows a circulation to the west northwest of Fairfield approximately 13 minutes before it touches down in Clay county. |
 |
 |
| 7:40 pm CDT 0.5 degree reflectivity scan zoomed in on Clay county. The tornado is located north of Fairfield just to the southwest of Clay Center. | 7:40 pm CDT 0.5 degree SRM (velocity) scan. The velocity product indicates a very strong circulation to the southwest of Clay Center. The velocity shows shear of over 170 kts with 81 kts of inbound wind and 91 kts of outbound wind. |
 |
 |
| 6:57 pm CDT 0.5 degree reflectivity scan zoomed in on Thayer county. Hook echo can be seen just to the west of Belvidere. The storm was moving to the east. | 6:57 pm CDT 0.5 degree SRM (velocity) scan. The velocity product shows the rotation in the tornadic thunderstorm. The radar algorithms recognized a Tornado Vortex Signature (TVS) which was displayed as a red triangle. |
 |
 |
| 7:14 pm CDT 0.5 degree reflectivity scan zoomed in on Thayer county. Hook echo remained very evident as the storm moved to the east. A tornado was reported with the storm until it exited the county. | 7:14 pm CDT 0.5 degree SRM (velocity) scan. The velocity product continued to show the tornadic rotation in the thunderstorm. |
