A broad upper level low pressure system slowly moved northwestward across the Texas Panhandle from the 15th through the 17th of July. The circulation around this low brought in copious amounts of moisture to the Panhandle. The Amarillo upper air sounding from the evening hours of the 16th showed climatologically above average Precipitable Water values of 1.2 inches. As peak heating was reached, scattered showers developed across the southern Texas Panhandle. Due to the above average moisture content in the atmosphere; these showers were able to produce highly localized heavy rain. This heavy rain led to minor urban flooding in Amarillo. The minor flooding quickly receded as the showers moved away from the city. As time progressed through the overnight hours of the 16th and the morning hours of the 17th, another round of heavy rain moved over Amarillo as the center of the low moved directly overhead. This caused another round of minor flooding on the southwest side of town during the morning commute. This minor flooding quickly receded as showers moved out of the city to the northwest.
