Solo Severe Thunderstorm Strikes Fear in Hidalgo County, March 26, 2015 Short Duration Large Hail Burst Brings Back Memories of 2012 |
|
![]() Hail photos shared on the NWS Brownsville Facebook Page from the Citrus City/Alton/Mission/McAllen area of Hidalgo County Nearly three years to the day (March 29, 2012), the fear of hail arrived in the McAllen metro area, courtesy of a single severe thunderstorm that developed quickly in rural eastern Starr County and roared into western Hidalgo County near Citrus City before racing through the cities of Alton/Mission, Edinburg/McAllen/Pharr and steadily weakening between Alamo and Donna. Unlike the hell of March 29, 2012, the storm of March 26, 2015 came in broad daylight (lunchtime) and dwelled briefly, with five to ten minutes of hailfall at any one location compared with the 45 minutes to one hour ravaging event in 2012. The largest hail ranged from half–dollar size to golf ball size in Mission, Alton, and Palmhurst (west McAllen) between 1 and 115 PM. Some of the stones had jagged edges, able to strip siding on some homes in these areas, cause minor dents/dings to vehicles, and crack an unknown number of windshields caught in the worst. The initial burst of hail came with 60 to 65 mph winds, which removed a poorly anchored roof of trailer home in Alton, and blew down some power lines and healthy large mesquite limbs. Winds dropped a bit as the cell moved over McAllen, reaching gusts of 43 mph at Miller Airport; lower gusts of little consequence occurred farther east in the Mid Valley before the storm weakened further. ![]() Initial severe thunderstorm warning issued at 1245 PM March 26 (yellow box), which included wording for damaging 70 mph wind and two inch diameter hailstones. Icons in the warning box are hail reports, between 1 and 130 PM; multicolored cluster is the severe storm as it moved into the warning box area. Damaging wind event described above was not included in prelminary storm report. |
![]() Four panel reflectivity image from Brownsville Doppler Radar. Areas in pink indicate values above 65 dbZ; purple, above 70 dbZ. A small area of 71 dbZ reflectivity at 25,000 feet is indicated in the lower right image, a clear indication of large hail (freezing level was around 13,000 feet)! Pattern Matters ![]() 7 AM Atmospheric sounding from Brownsville, with unstable layer conducive to rapid ascent (lift) shown above a fairly strong inversion. That lift would be provided by the approach of an upper level disturbance (red L and green arrow) from west Texas and a deepening full latitude trough and associated surface cold front (blue arrow). |
