We were in good shape for the start of this chase — Del Rio, Texas. \u00a0A front or prominent outflow boundary was sagging southward (east-west orientation, more-or-less) in the Del Rio vicinity, with hot and moist to the south and mild and moist to the north. \u00a0Check out those temperatures on the surface map above. \u00a0 Temps are near 80F in the Del Rio area and in the 70s north of the front, and around 100F at Laredo and east of there. \u00a0Surface winds were backed nicely beneath 70-knot SW flow at 500 mb. \u00a0Instability and shear were excellent for supercells, and the tornado threat was good but not great.<\/p>\n

After lunch we headed up to the northwest edge of Del Rio. \u00a0We basically just had to wait for something to develop on the higher terrain near the boundary west of the Rio Grande and then move eastward with it. \u00a0That plan worked out just fine. \u00a0We moseyed to the northeast side of Del Rio on some slightly higher terrain for a decent view. \u00a0It was somewhat hazy, and eventually we could see some storm structure and a good-sized lowering.<\/p>\n
