Forecasters say a dust storm about 100 miles wide blanketed much of the Texas Panhandle overnight Tuesday before moving on and dissipating.
The National Weather Service said a cold front that moved through Tuesday night had winds up to 60 mph and spread dirt picked up from Colorado and Kansas.
Forecaster Nicholas Fenner in Amarillo said Wednesday that dry conditions in Texas contributed to the dust storm that towered about 2,000 feet.
Fenner said the dust storm also reached the Oklahoma Panhandle.
He said the dust was so heavy that evidence of the storm turned up on National Weather Service radar, with the system reaching as far south as Lubbock.
The Texas Department of Public Safety had no reports Wednesday of any road closures or anyone hurt from the dust storm.
