Back-to-Back Pacific Storms to Impact the West Coast; Heavy Snow in the Central Appalachians

Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the week. Read More >

An unusual weather setup produced a very narrow and isolated band of snow across parts of Dodge City and Ford county on 1/19/11. The atmosphere was cold and moist with low clouds and fog preceding the formation of the snow. It appears that two slaughter plants and a power generating plant contributed to the snow as ice nuclei and copious amounts of water vapor were fed into the boundary layer. East/southeast winds carried the vapor and nuclei aloft into the lower clouds and then precipitated out as snow downwind of the source. Snowfall of as much as 0.7" was reported in the snowfield with no snow observed at all outside of this area.

The image below shows the source of the snow and the area of Dodge City and Ford county that was covered by the snow.

The next image shows a radar image depicting the snow band at 1124 AM. The orange and pink colors show where the heaviest snow was falling at the time.

The following 2 1/2 hour radar loop shows where the snow persisted (this may take a minute to load). Also of note, try and pick out the moving object that is headed towards the southwest from Dodge City along the highway. This is actually a train that was headed slowly towards Montezuma, parallel to the highway!
