A slow moving upper low moved east across the northern Permian Basin late in the night on Friday before exiting the region Saturday afternoon. Northwest of this low, a large deformation zone developed accompanied by moderate to heavy snow.  At the height of the storm around 6 AM Saturday, snowfall rates were measured as great as 2 inches per hour by NWS employees. The result was a large swath of heavy wet snow between 4 and 10.5 inches spanning 16 counties across the South Plains and Rolling Plains, with lesser amounts elsewhere.
Snow covered and icy roads severely hampered travel over the region through the weekend and resulted in sizable economic losses, particularly for some Lubbock businesses. Some roads such as the South Loop 289 flyover were closed due to hazardous ice buildup.  Hundreds of minor auto accidents were reported in Lubbock County alone, with similar numbers occurring Saturday night through Sunday night following refreezing of water on area roads and overpasses. Monetary losses were not available at the time of this entry.
This snowstorm was unique in that many weather models leading up to the event severely failed to capture the magnitude and extent of the snowfall. The official forecast favored a low impact event with 1 to 4 inches of total snowfall. Much of the rationale for low snow amounts was attributed to the upper low forecast to weaken and shear apart as it passed just south of the region. However, the upper low remained intact and even slowed its eastward progress thereby prolonging the duration of moderate to heavy snow over much of the South Plains.  The high water content of this snow proved beneficial in restoring soil moisture to much of the region.
