| Brief Description: EVENT NARRATIVE: Although a tornado was never reported during the time of issuance, later public reports and a NWS Storm Survey indicated in fact there was a tornado. Based on radar estimates, tornadic damage began sometime around 4 PM CST about 28 miles north of Dryden, TX. This is where a 30 gallon fiberglass tank was destroyed, in addition to another chemical tank. Pieces of the fiberglass tank were found downwind. A set of metal stairs that appeared to have been welded to the tank were also found downwind and were no longer attached to the tank. As the tornado tracked southeastward, its debris field of rocks, gravel and tree limbs stripped the paint off of a recently painted 300 gallon storage tank. The tornado continued on its path and weakened after stripping some cedar trees sometime around 404 PM CST. Please see the attached images for damage photos and a detailed image of the tornado's damage path. EPISODE NARRATIVE: During the afternoon of April 29, 2009, a surface low developed near Raton Mesa with a dryline extending from the eastern NM/TX border to the Davis Mountains of west Texas. Strong daytime heating resulted in mixed layer CAPE values near 3000 j/kg. As a strong southern stream mid-level jet max approached, favored kinematic profiles lead to the rapid development of supercells across southwest Texas. Although coverage remained fairly isolated due to weak upper level support, upslope/backed flow did result in at least one tornado being observed. | |||||||||||
