Flash Flood — Oct 8, 2018
An upper level trough was centered near the Four Corners region which brought an increase in upper level lift across West Texas. The area was in a favorable position under the upper level jet stream which also aided in lift. A plentiful supply of moisture was in place and wind shear was favorable for thunderstorm development across West Texas. These conditions resulted in strong winds, hail, fl...
Flash Flood — May 30, 2016
An upper trough was off the Pacific coast and was moving inland over California and Arizona. This put West Texas and southeast New Mexico under southwest winds aloft. A dryline was backed up against the mountains leaving good moisture with 50 degree dewpoints off to the east. The dryline and boundaries across the area became the focus for thunderstorms. Lapse rates and instability were hig...
Flash Flood — Jun 13, 2008
An upper level high pressure system centered across northern Mexico and west Texas began shifting westward. Meanwhile, westerly mid-level flow on the northern periphery of this system steered a weak upper level disturbance towards the region. This, in combination with the presence of instability and abundant moisture, set the stage for thunderstorm development across Permian Basin and Western L...
Flash Flood — Mar 11, 2007
First tornado watch/severe weather event for the season. An upper level storm system approaching west Texas and southeastern New Mexico set off severe thunderstorms across the area on March 11. Copious amounts of mid and low level moisture contributed to high rainfall totals and instances of flash flooding.

A cold front that stretched from the Davis mountains northeast across the Permian Basin initiated a series of training thunderstorms that persisted over the Permian Basin for 48 hours. Rain began on the afternoon of the 13th and continued through the afternoon of the 15th causing major flooding problems across the area. The Colorado River and the Rio Grande went into flood and flash flooding ...
