In order for there to be any appreciable rain in western Texas, there must be a broad southeasterly flow from the Gulf of Mexico. The moisture has been there, but it is not being drawn far enough west by storms developing over the Plains.

The same scenario will unfold on Thursday as a storm moves from Colorado to Oklahoma. The circulation around the storm will transport dry air from the arid Southwest into western Texas which will again prevent any rain. At the same time, the atmosphere will moisten in eastern Texas and the lower Mississippi River Valley which is where we expect rain to break out.

The dry, windy conditions due across western Texas on Thursday will definitely increase the threat of quickly spreading wildfires.
