How is that possible? It hasn't passed Dallas yet.
I just posted this on the KHOU Board with the same basic question...
Simple way to think of it is like syrup pouring down the terrain. When the Deeper Air Mass sinks into TX from the Panhandle, it surges down the Permian Basin into the Hill Country and points S. In the RGV the terrain is a bit lower in elevation than points E. Part of the reason we watch areas near Austin and San Antonio here in Houston is because the Air Mass tends to drop off the Escarpment into the Colorado and Brazos River Valley areas and on into Grimes, Austin, Waller, and NW Harris Counties. Very simple explanation.. Hope it helps
