A winter storm system will rapidly intensify over the Midwest on Sunday and track through the Great Lakes on Monday. Periods of heavy snow are anticipated across the Upper Great Lakes late Sunday and continuing into Monday. At least 1/10 inch of ice accumulation is expected from a wintry mix across much of the interior Northeast U.S. starting Sunday afternoon. Read More >
Overview
|
During the afternoon and evening of May 22, 2004, ingredients came together for an outbreak of severe thunderstorms and tornadoes across east-central and southeast Nebraska into western Iowa. Nine tornadoes were reported, including an F4 that devastated the small town of Hallam. The Hallam tornado which initially touched down at 7:30 PM CDT just west of Daykin, tracked 52 miles across portions of Jefferson, Saline, Gage, Lancaster and Otoe counties, before lifting at around 9:10 PM CDT just west of Palmyra. In addition to the tornadoes, hail to four inches in diameter was observed, as were damaging straight-line winds. |

Damage Survey Report
A survey was conducted by the National Weather Service in Valley, NE of the tornado that struck Hallam on Saturday, May 22nd. The following is an overview of damage along the track.
The tornado started 2 miles north of Daykin, Nebraska and traveled east-northeast to about 1 mile south of western and continued to about 2 miles north of Swanton. The tornado was rated F0 to F1 on the Fujita damage scale. Much of the damage was due to farm outbuildings, grain bins and trees.
The tornado remained F0 to F1 until it struck the southern portions of Wilber where it strengthened to F2. Roofs blown off of homes occurred just southeast of Wilber. The tornado from Wilber to north of Clatonia to Hallam grew to its most intense stage. The tornado's path width also increased to an unprecedented two and one-half mile. The F-Scale rating for the storm was F4 from about Clatonia to Hallam. Many well-built homes were demolished. Grain bins, farm sheds and outbuildings and trees were demolished along this section of the path. Hallam itself escaped the strongest winds of the storm, which were south of the town. Nevertheless, many of the structures in Hallam were rated F2 to F3. The storm also toppled hopper cars from a freight train on the west side of the town. The tornado then tracked east for several miles prior to turning northeast again. The storm narrowed to about a mile wide as it passed just north of Cortland and about 2 miles north of Firth. The Norris schools north of Firth received severe damage with the roof of the middle school auditorium collapsed and several walls caved in. School busses were tossed. Several homes northeast of the schools were flattened where the storm was again rated F4. Damage continued northeast to Holland and 2 miles north of Panama. The tornado was slightly weaker in this section (F2 at the most) and began to narrow. The track then curved more to the north, just to the south of Bennet where some homes received F3 damage. After passing to the south of Bennet, the storm moved back to the northeast and began to weaken to F0 to F1 strength. The track also was becoming narrower. The tornado then dissipated 1 mile west of Palmyra.
Radar:
Reflectivity and Storm-Relative Velocity Data for the Hallam Tornado
 |
 |
 |
 |
| Reflectivity and storm-relative velocity loop of the Hallam tornado. The loop is centered on the storm, so the background map is actually moving. | Reflectivity 01:07Z (8:07 PM CDT) This radar image shows the supercell as it was moving through Saline County. The red colors indicate very heavy rain or hail, with lighter rain indicated by the yellow, green, and blue colors. The tornado clipped the southern portion of the town of Wilber, with the main part of the tornado passing just south of Wilber. There is a hook echo that has completely wrapped around to form a "donut" shape echo between the towns of Wilber and De Witt. This donut echo is associated with the tornado. | Storm-Relative Velocity 01:07Z (8:07 CDT) This radar image shows the wind velocity within the supercell thunderstorm. The green and blue colors indicate winds blowing toward the radar, and the red, orange, and yellow colors indicate winds blowing away from the radar. Just southwest of Wilber the radar is showing a 105 mph wind blowing toward the radar, right next to a 69 mph wind blowing away from the radar. This is known as a "velocity couplet," and is often associated with the mesocyclone in the supercell. The radar typically does not actually measure the winds inside the tornado, but rather the "parent" mesocyclone that the tornado forms out of. | Reflecitivity 01:24Z (8:24 PM CDT) This reflectivity image shows a more classic looking hook echo, moving out of Saline County and into the northwest corner of Gage county and the southwest corner of Lancaster County. The hook echo, and the associated tornado, is between Hallam and Wilber. |
 |
 |
 |
 |
| Storm-Relative Velocity 01:24Z (8:24 CDT) At this time, the velocity image is showing winds of 90 mph blowing toward the radar, and 113 mph blowing away from the radar. | Reflectivity 01:28Z (8:28 PM CDT) The hook echo now stretches from the town of Claytonia to the town of Hallam. | Storm-Relative Velocity 01:28Z (8:28 CDT) The velocity couplet is shown just west of Hallam, about to move into the Hallam area. The wind speeds, as indicated by the radar, in the mesocyclone are 83 mph toward the radar and 100 mph away from the radar. | Reflectivity 01:33Z (8:33 PM CDT) The hook echo at 8:33 PM completely engulfed the town of Hallam. This was when the tornado was near its widest point of approximately 2 ½ miles. The town of Hallam was near the northern edge of the tornado path. |
 |
|||
| Storm-Relative Velocity 01:33Z (8:33 CDT) The tornado was passing over Hallam at 8:33 PM, and the radar velocity winds were 79 mph toward the radar and 92 mph away from the radar. Because the radar is measuring the winds in the mesocyclone, the wind speeds do not necessarily correlate to the strength of the tornado, because the tornado was rated a F4 at the time of this radar image. There are many factors and variables which determine the radar's ability to measure the wind speeds inside the mesocyclone. Despite the slightly lower winds on the radar, this is still considered an extremely strong velocity couplet. |
