Cold Fronts for Western and Eastern U.S. Early This Week

A cold front will work across the Eastern U.S. through Monday with scattered rain showers and thunderstorms before broad high pressure brings quiet weather by Tuesday. Across the Western U.S., a cold front will shift across the region through Tuesday. An Atmospheric River following the front will bring heavy coastal rain and high elevation snowfall to portions of the Northwest. Read More >

 

The May 22nd, 2004 

Tornado Outbreak

 

          May 22, 2004 was one of the worst severe weather outbreaks that affected south central and eastern Nebraska during the afternoon and evening hours.  In south central Nebraska, no less than 17 different tornadoes rolled across the area, and the devastating Hallam, NE tornado also occurred in eastern Nebraska on this day.  The tornadoes in south central Nebraska damaged dozens of homes and a few were completely destroyed.  In addition, over 250 center irrigation pivots were affected and hundreds of power poles were snapped, resulting in many miles of downed electrical line.  Large hail and strong straight line winds (up to 80 mph) also wreaked havoc on the region.  In the end, property damage of over 17 million dollars, and about 5 million dollars in crop damage was reported. In todays numbers, the total damage across south central Nebraska totaled nearly 30 million dollars.

  

Moderate to High Risk for Severe Weather was Forecast

          With a warm front sitting across south central Nebraska on the morning of May 22nd, 2004 and very unstable atmospheric conditions in place, much of south central Nebraska was placed under a moderate risk for severe weather by the Storm Prediction Center (SPC) in Norman, Oklahoma at 7 AM CDT. As conditions ripened, a High Risk for severe weather was advertised for portions of the local area later that day. See the images below for  the probabilities of severe weather issued by SPC as the event was developing.

          Contributing to the high probabilities for severe weather was the atmospheric set up on May 22nd, 2004. The 7 AM EST surface map below shows a dry line across western Kansas, a stationary warm frontal boundary draped across south central Nebraska, and a cold front to the west which was expected to charge eastward later that day. In the upper levels of the atmosphere, the 500 mb analysis below (also valid at 7 AM EST) depicts a large trough of low pressure across the intermountain west, with a low diving southward across the pacific Northwest, and an upper level perturbation near the four corners region.

Synopsis for the Day

          During the early morning hours of May 22nd, 2004, an upper level trough across the intermountain west was positioned to shift eastward as an upper level low across the pacific Northwest was diving south.  At the same time, an upper level wave embedded in this trough was forecast to emerge into the plains during the afternoon hours. Ahead of this disturbance, a dry line was positioned across western Kansas with a cold front expected to blast across the region later in the day. With very good deep layer shear and instability across the region, this dryline was expected to be the focus of covection initiation later in the day, with the overall potential for severe weather on the high side - especially across portions of Nebraska where a moderate risk for severe weather had been forecast by the Storm Prediction Center (SPC) in Norman, Oklahoma at 7 am CDT. This risk was later upgraded to a high risk for severe weather as the event was unfolding.

The Developing Storms that Evening

         As expected, the storms initiated along the boundary of drier air to the west, and more moist air to the east. Thes storms then propagated along the warm frontal boundary to the north, tracking from west to east during the late afternoon and evening hours.

          While no less than 17 tornadoes were observed across south central Nebraska on May 22nd, 2004, the severe weather was not just limited to Nebraska (see map on left below). In addition to the 86 tornado reports across the country that day, there were hundreds of damaging wind and large hail reports (tornadoes are depicted in red, wind reports are depicted in blue, and large hail reports are depicted in green). The actual tornado tracks across the local area are depicted to the right below.
