Shortly after midnight on the 12th, the base of an upper-level trough exited southern New Mexico before bisecting the South Plains during the day as it moved eastward. With a cold layer of air already in place at the surface, very mild and moist southerly winds aloft developed ahead of the trough and led to a plethora of precipitation types developing during the pre-dawn hours. Generally along and south of the storm's track, scattered thunderstorms with locally heavy rains, small hail up to 1/2 inch in diameter and even sleet were observed. Farther north in the northern South Plains and southern Texas Panhandle, the cold air remained deep enough for precipitation to fall as all snow. The snow fell heavy at times during the morning, but did not result in any known travel problems. By mid-day, the snow tapered from west-to-east behind the departing storm system, but not before depositing up to 5 inches of wet snow in some locales.
Selected snow totals include: 5 inches at Happy (Swisher County) and Memphis (Hall County), 4 inches at Nazareth (Castro County), Tulia (Swisher County), Silverton (Briscoe County), and Flomot (Motley County), 3 inches at Dimmitt (Castro County) and Plainview (Hale County), 2 inches at Friona (Parmer County), 1.5 inches at Floydada (Floyd County) and Matador (Motley County), and 1 inch at both Farwell (Parmer County) and Childress (Childress County). Also, this storm produced beneficial liquid equivalent precipitation of 1/3 to nearly 1 inch over all but the far western South Plains where little if any precipitation materialized.
