A cut off upper level low set up residence over the central US during the week of the 29th. This caused an unseasonably deep surface low pressure system to develop over Missouri.  The deepness of this low caused a tightening of the pressure gradient over the Texas Panhandle on the 29th. The strong pressure gradient caused a combination of high wind gusts and sustained winds from roughly 8 AM CST and persisted until 5 PM CST. The high winds caused crosswinds on east-west oriented roads which led to an semi-tractor trailer and a camper trailer to overturn on Interstate 40 near mile marker 81 (Carson County). By 5 PM CST, the surface low had progressed northeastward towards the Great Lakes which allowed the pressure gradient across the Texas Panhandle to diminish and bring an end to high wind conditions.
