A major winter storm impacted the South Plains, Rolling Plains, and extreme southern Texas Panhandle from late on the 9th through the 10th. A strong upper level low pressure system moved to the southeast across the Intermountain West on the 9th emerging in New Mexico late in the evening. The system then tracked into southeastern New Mexico and eastward on the 10th. Snow began late on the 9th in the western South Plains and spread eastward early on the 10th. As the upper level system moved away from the area late on the 10th, lingering light snow continued into late in the afternoon tapering off from west to east. The largest swath of heavy snow fell across the southwestern South Plains. This storm system brought a larger swath of heavy snow to Colorado, Texas, Oklahoma, Louisiana, and Mississippi.
