During the late night hours of the 11th and early morning hours of the 12th, an upper level trough of low pressure moved out of southern New Mexico and into west central Texas. This placed the Texas Panhandle on the left front quadrant of 120 to 140 mph jet streak and within the warm sector of an 850mb closed low. This closed low brought moisture from the Gulf of Mexico over the cold surface airmass. This moisture coupled with the lift from the jet streak to initiate snow showers over eastern New Mexico just prior to midnight on February 12th. These showers expanded eastward quickly to enter the Texas Panhandle around 12:30 AM CST. Snow showers quickly produced 1 inch of snow in Dalhart (Dallam and Hartley County), and local law enforcement reported periods of near zero visibilities. Bands of enhanced snow showers developed as the upper level trough of low pressure took on a more negatively tilted orientation by 6 AM CST. These enhanced bands quickly produced multiple inches of snow across the Panhandle, and made driving hazardous due to near zero visibilities. No injuries were reported, but multiple single vehicle accidents were reported across the area. By noon, the upper level trough was over the eastern Texas Panhandle causing snow to end across the far northwest. The remaining snow showers across the Panhandles ended by 3 PM CST as the 850mb closed low moved over east Texas, removing the necessary moisture to support snow. Storm total amounts of 4 to 9 inches were reported across the Texas Panhandle. COOP and CoCoRAHS observers at Dalhart (Dallam County), Borger (Hutchinson County), Amarillo (Potter County), and Boys Ranch (Oldham County) provided liquid equivalent values to show snow to liquid ratios ranged between 10 to 1 and 16 to 1. Also the 4.7 inches of snow at Amarillo broke the old record daily maximum snowfall of 2.4 for February 12th set in 2004.
The following is a list of the highest snowfall totals per county: 8.0 inches in Claude (Armstrong County); 8 inches in Skellytown (Carson County); 6 inches in Wellington (Collingsworth County); 8 inches in Dalhart (Dallam County); 3 inches in Hereford (Deaf Smith County); 9 inches in Clarendon (Donley County); 9 inches in Pampa (Gray County); 6.0 inches in Spearman (Hansford County); 7.0 inches in Dalhart (Hartley County); 6.0 inches in Canadian (Hemphill County); 7.0 inches in Fritch (Hutchinson County); 6.0 inches in Darrouzett (Lipscomb County); 5.5 inches in Dumas (Moore County); 5.0 inches in Perryton (Ochiltree County); 4.0 inches in Vega (Oldham County); 6.5 inches in Amarillo (Potter County); 7.0 inches in Palo Duro Canyon (Randall County); 7.0 inches in Stratford (Sherman County); 4.0 inches in Wheeler (Wheeler County); and 6.0 inches in Miami (Roberts County).
