During the early morning hours of the 18th multiple high wind gusts were reported across the southern Texas Panhandle. Light showers formed across southwestern Randall County around 1:30 AM CST in response to a weak upper level trough moving northeastward out of New Mexico. However, the atmosphere below the cloud bases was extremely dry and evaporated precipitation prior to reaching the ground. Just before 2 AM CST, these virga showers moved over Palo Duro State Park (Randall County) where the accelerated downward motion caused by evaporation produced a 69 mph non-thunderstorm wind gust. This wind gust was measured by the West Texas Mesonet site in the park. The showers moved to the northeast into Potter County, and crossed over the Amarillo International Airport (Potter County). While over the airport, the showers produced another 69 mph wind gust at 2:32 AM CST, which was measured by the National Weather Service ASOS. The showers moved into Gray County by 4 AM CST, and began to show signs of diminishing. As the showers collapsed over Pampa (Gray County) they produced high winds, and a member of the public reported several small trees had become uprooted at 4:30 AM CST. With the showers diminished no further reports of high winds were received through the rest of the morning hours.
Showers redeveloped during the afternoon hours of the 18th as a stronger upper trough across New Mexico and Colorado approached the Texas Panhandle. The dry sub-cloud layer was still in place, and caused precipitation from these showers to evaporate prior to reaching the ground. The strengthened downward motion produced high wind damage 19 miles south of the city of Perryton (Ochiltree County) at 4:33 PM CST. The Ochiltree Sheriff���s Office reported that power poles on US Highway 281 between County Road 70 and County Road 83 had been blown down onto the road. By 5:00 PM CST, the showers had moved east of Perryton before producing additional high wind damage. The Ochiltree Sherriff���s Office reported that power poles along US Highway 377 between Count Road 20 and County Road 21 had been blown down onto the road. By 5:15 PM CST, the showers had moved over the Texas Department of Transportation AWOS site east-northeast of Perryton where a 58 mph wind gust was measured. Shortly after producing this gust, the showers dissipated as storm outflows from the Oklahoma Panhandle eliminated the inflow for these showers.
