Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the week. Read More >
Overview
Friday, June 2nd-3rd 2017
Plenty of moisture was being brought northwest on southeast surface winds. The winds aloft were very light. A small upper level disturbance was nearly stationary just to the southwest of Hereford, TX. This disturbance teamed up with the abundant moisture to help produce thunderstorms across the south central and southwest Texas Panhandle Friday afternoon. The activity initially developed over western Potter and western Randall Counties into eastern Oldham and eastern Deaf Smith Counties. The thunderstorms moved very slowly west away from Amarillo. Then an outflow boundary started moving east from the initial activity. More storms started to develop eastward behind the eastward moving boundary. The heavy rain producing thunderstorms slowly moved and developed eastward into the western half of Amarillo. The thunderstorms then remained almost stationary or slowly drifted off to the south. The intense rainfall (at least 2 inch an hour rainfall rates) fell over the western half of Amarillo and caused flash flooding in this area. Rainfall amounts were generally in the 2 to 4 inch range with locally higher amounts. All of the rain fell in less than a 2 hour time span. On Saturday, the 3rd, an upper level disturbance moved southward toward the panhandles. This disturbance helped to produce heavy rain producing thunderstorms again over western and central Amarillo. Rainfall amounts were generally in the 1 to 2 inch range.
