A storm system moving out of the Rockies sent a powerful cold front through the southern Texas panhandle, South Plains, and Rolling Plains during the early evening hours of the 17th. The cold front surged at 55 mph as it moved across the South Plains. Extreme pressure rises behind this front on the South Plains created a widespread high wind event along with a haboob. Visible satellite images estimated the width of the haboob to be around 250 miles extending from eastern New Mexico through the South Plains. Visibilities were reduced across much of the South Plains below one quarter mile and zero at some locations.
Widespread damage was also observed with the most extensive damage in the Lubbock area. Additionally, one wildfire was intensified by the severe winds in Garza county. Smoke from this wildfire caused the the closure of US Highway 84 between County Road 220 and Highway 380.
